When enterprises move AI workloads from pilot to production, data delivery often becomes the factor that determines whether those systems can scale reliably. Point-to-point architectures connecting storage directly to compute hold up under demonstration conditions, but they often break down under sustained, concurrent production traffic. The result is stalled inference pipelines, delayed RAG systems, underutilized GPUs, and SLA violations, all of which carry direct business consequences.
“Organizations successfully operationalize AI when their infrastructure is built to handle real-world failures, not just controlled conditions,” says Hunter Smit, senior manager of product marketing at F5.
In a pilot, a stalled transfer is an inconvenience, while in production, that same stall is an outage someone now owns. The underlying architecture is often identical in both cases: when a client is wired directly to storage, the system becomes increasingly fragile under sustained, concurrent production traffic because that direct connection has no answer when a node fails or traffic spikes. From there, retries and timeouts cascade, and the entire pipeline backs up right at the moment the business is depending on the output.
“Point-to-point architectures, where the S3 client connects directly to S3 storage, are not resilient,” says Paul Pindell, principal solutions architect for technology alliances at F5. “If a single storage node fails, all traffic to that cluster degrades, and in some cases the cluster can fail entirely.”
The problem is that AI workflows, including RAG-based inference and agentic AI, increasingly treat S3 storage as a first-class citizen in the AI cluster. However, the network connectivity between that storage and the cluster was never designed for the high-throughput, uninterrupted data movement that’s needed to keep GPUs running optimally.
“Enterprise leaders tend to frame AI infrastructure around GPU utilization, but what makes AI different from traditional deterministic workloads is that infrastructure continuously influences those outcomes at every interaction,” says Tanu Mutreja, senior director of product management at F5. “In AI environments, infrastructure is no longer just a back-end concern. It shapes customer experience, quality, resilience, and cost with every transaction.”
There can be significant business consequences. For instance, when inference pipelines stall, it becomes an SLA and customer experience issue. When RAG systems are delayed, models lose access to timely, relevant context, which results in inaccurate, outdated, or hallucinated responses, all of which create operational, compliance, and reputational risks. At the same time, the infrastructure issues that create those problems can also drive up costs by leaving expensive GPU resources idle or underutilized.
“When GPUs are underutilized, it signals infrastructure inefficiencies that inflate costs while limiting scalability and responsiveness,” Mutreja says. “The leadership question is whether the end-to-end AI infrastructure consistently delivers reliable, secure, high-quality, and governed AI experiences at sustainable unit economics.”
F5 treats data delivery as a first-class infrastructure layer rather than assuming the network path will simply work. Where application delivery optimized the flow of requests between users and applications, data delivery optimizes the flow of data between storage, networks, and compute, including AI compute.
Making data delivery a first-class layer means building three properties into it:
Observability provides real-time visibility into latency, throughput, and flow health.
Programmability enables policy-driven control over how data moves, through dynamic routing, traffic optimization, rate management, and automated failover.
Failure-awareness builds resilience for degraded networks, storage throttling, and service disruptions.
In the architecture F5 has developed for Dell ObjectScale, F5 BIG-IP sits between ObjectScale and AI compute as a programmable control point at the storage edge.
“We have seen cases where a misconfiguration in the AI compute layer effectively DDoS’d the S3 storage infrastructure, ” Pindell says. “Not in a malicious way, more of an ‘Oh no, what did I do?’ moment, but it still took storage down for the entire organization.”
Placing BIG-IP as the application delivery controller between the storage and compute layers protects storage with QoS, rate limits, and connection limits, keeping it resilient and operational under that kind of load. SecureIQLab-validated testing confirmed that this protection does not come at the cost of throughput, which matters architecturally, Pindell says.
“Preserving, and even improving, throughput is a must-have,” he explains. “It’s what lets you layer on the higher-level functionality, resilience and enhanced security, without giving up performance to get there.”
AI deployments in hybrid multicloud environments have an even greater data delivery challenge because of the heterogeneity involved. In other words, data traversing these environments must contend with inconsistent policies, security controls, identity systems, governance requirements, fragmented visibility, and distinct failure boundaries.
Programmable traffic management and observability address this complexity together. Observability provides a unified view of application, network, and infrastructure health across otherwise disconnected environments. Programmable traffic management uses those insights to intelligently route, balance, and fail over traffic in real time. Together, they create a closed-loop feedback system that enforces consistent policies, improves resilience across failure domains, and ensures reliable, high-performance AI data delivery regardless of where applications, data, or users reside.
The organizations that move beyond perpetual pilots share a specific engineering discipline, Smit says.
“They’re the ones that reach for production design with failure as the normal state, not the exception,” he explains. “They will assume latency, congestion, and partial outages will happen. And they build a data path observable and failure-aware enough to absorb them, with explicit mitigation for every degraded condition rather than a hope that the network will hold.”
Organizations stuck in perpetual pilots are still optimizing for the perfect lab result and discovering the real-world gap only when a workload goes live. The issue is not model quality or GPU count, but whether the data delivery layer was engineered with the same rigor as the compute.
“Teams need to understand that a real-world network behaves very differently from an optimized lab network,” Pindell says. “They need a mitigation plan for the failure states and performance bottlenecks they will hit in production.”

Last night, the increasingly enterprise-focused AI startup Sakana launched Fugu, a multi-agent orchestration system that delivers frontier-level AI performance through a single, OpenAI-compatible API.
Designed for developers, enterprises, and nations seeking resilience against vendor lock-in and geopolitical export controls, Fugu (Japanese for “pufferfish”), bypasses the traditional monolithic model structure by dynamically routing queries to a swappable pool of specialized AI agents.
Sakana CEO and co-founder David Ha, formerly of Google Brain, positioned Fugu as a more reliable option for enterprise workflows than any single AI model provider in the wake of Anthropic’s move on June 12 to revoke public access to its most powerful models, Claude Mythos 5 and Claude Fable 5, in the wake of a U.S. government export control order. As Ha wrote in a post today on X:
“Fugu dynamically orchestrates the world’s best models to tackle complex tasks. We are proving that a well-orchestrated pool of swappable agents can match restricted frontier models like Fable and Mythos.
But Fugu is about more than just performance. I believe that Orchestration Models are the next frontier, beyond bigger models.
Relying on a single company’s model for national infrastructure is a massive risk. As recent export controls have shown, access to top models can disappear overnight.
Collective intelligence is the practical hedge against this concentration of power. Fugu simply routes around vendor restrictions by relying on an entirely swappable agent pool.”
Sakana AI explicitly states that the specific models Fugu selects and how it coordinates them are proprietary, meaning this routing information is hidden from the user by design. The documentation only refers generally to a “diverse pool of powerful models,” “multiple LLMs,” or “specialized models” without providing a specific count.
By acting as a sophisticated coordinator rather than a standalone foundation model, Fugu matches the output quality of top-tier models like Fable and Mythos on third-party benchmarks of agentic tasks, while fundamentally altering how developers deploy critical AI infrastructure.
At its core, Sakana Fugu operates like a master general contractor. When presented with a complex request, Fugu does not attempt to execute every step itself.
Instead, it breaks the problem down, delegates sub-tasks to a pool of expert foundation models, verifies their work, and synthesizes the final output.
“Fugu is itself an LLM, trained to call various LLMs in an agent pool, including instances of itself recursively,” the Sakana AI team noted in their technical release.
Grounded in two of Sakana’s 2026 research papers, TRINITY and the Conductor, the system autonomously manages the entire lifecycle of model selection and verification using learned coordination strategies rather than hand-designed workflows. To the end user, this multi-agent swarm is entirely abstracted behind a standard API endpoint.
Sakana AI is offering two variants of the system to cater to different operational workloads:
Fugu: A high-speed, low-latency model optimized for everyday tasks. It is designed to act as the default engine for interactive chatbots and integrates directly into coding environments like Codex.
Fugu Ultra: The flagship tier engineered for complex, high-stakes tasks such as AI research, cybersecurity analysis, and multi-step patent investigations. According to Sakana, Fugu Ultra coordinates a deeper pool of experts and matches industry-leading monolithic models across rigorous scientific and reasoning benchmarks.
Additionally, on the pay-as-you-go plan, standard Fugu charges a dynamic rate based on the specific underlying models activated, whereas Fugu Ultra utilizes a fixed pricing structure starting at $5 per million input tokens and $30 per million output tokens.
As indicated by benchmark charts shared by Sakana, Fugu actually exceeds the performance of Anthropic’s Claude Fable 5 on LiveCodeBench, an open source benchmark testing coding performance on regularly refreshed, software problem-solving tasks (Fugu Ultra: 93.2, Fugu: 92.9, Fable: 89.8), and beats the prior Claude Mythos Preview model on GPQA-D (Diamond) , a test of 198 graduate-level multiple-choice questions in biology, physics, and chemistry (Fugu Ultra: 95.5, Fugu: 95.5, Mythos Preview: 94.6).
By orchestrating multiple models from different providers, Fugu essentially builds native redundancy into the AI stack. If one provider suffers an outage or faces sudden regulatory restrictions, Fugu routes around the disruption to maintain uptime.
Fugu is offered as a commercial, proprietary API service, not an open-source framework.
Because Sakana’s core intellectual property lies in its non-obvious collaboration patterns, the specific routing information—meaning exactly which underlying models Fugu selects for a given query—remains proprietary and is intentionally hidden from the user.
However, Sakana offers critical controls for enterprise data compliance. Developers can explicitly opt specific models or providers out of their Fugu routing pool to maintain strict corporate privacy standards.
Additionally, users can opt out of having their prompts used for future training data. Geographically, Fugu is restricted from operating within the European Union (EU) and European Economic Area (EEA) while Sakana works to align its black-box data routing architecture with GDPR regulations.
Fugu is available immediately in most regions—with the temporary exception of the EU and EEA—at subscription tiers and pay-as-you-go pricing.
Teams can opt for monthly subscription allowances designed for individual or hands-on use: a Standard tier at $20/month for lightweight workflows, a Pro tier at $100/month providing 10x standard usage, and a Max tier at $200/month offering 20x usage for continuous, long-running tasks. I wasn’t able to find the actual amount of tokens covered under these plans, but I’ve reached out to Ha on X for more information.
As part of the initial rollout, Sakana is offering a free second month for users who subscribe to any tier by July 31, 2026.
For enterprise scaling and production deployments, Sakana offers an elastic pay-as-you-go plan. Crucially for high-stakes environments, requests made under this consumption-based model are served at a higher priority than those from monthly subscription plans.
Under this framework, the standard Fugu engine charges the single rate of the highest-tier underlying model involved in a query, without ever stacking multi-agent fees. The flagship Fugu Ultra tier (fugu-ultra-20260615) utilizes a fixed pricing structure per one million tokens: $5 for input, $30 for output, and $0.50 for cached input. These rates increase to $10, $45, and $1.00 respectively for extreme workloads utilizing context windows above 272K tokens. That puts it among the more expensive options compared to single AI models via provider APIs:

Developers modeling operational costs should also note a significant architectural caveat in how Fugu bills for its multi-agent capabilities. According to the developer documentation, Fugu Ultra’s API responses include detailed usage fields that separate user-visible token generation from internal orchestration work. The background tokens consumed and generated when Fugu delegates sub-tasks, verifies code, or routes between underlying agents are not absorbed by the provider; they represent real token usage and are counted toward the final price of the request at standard rates.
To understand Fugu’s position in the mid-2026 AI ecosystem, it is critical to distinguish between model routing and multi-agent orchestration.
Over the past year, enterprise adoption of standard routing platforms—such as Not Diamond, Martian, and the open-source RouteLLM framework—has skyrocketed. These systems act as intelligent air traffic controllers; using semantic classifiers or meta-models, they analyze an incoming prompt and predict which single foundation model will yield the highest quality or most cost-effective response, dispatching the query accordingly.
Fugu operates on a fundamentally different paradigm. Rather than making a one-shot routing decision, Fugu aligns more closely with complex multi-round systems like Router-R1 (a framework introduced at NeurIPS 2025). It breaks a query down, interleaves reasoning with delegation, and dynamically assigns sub-tasks to multiple models in parallel or sequence before synthesizing a final output.
While frameworks like LangGraph, CrewAI, and Microsoft AutoGen offer developers the tools to build similar multi-agent systems, they require immense manual configuration—defining roles, setting up conditional edges, and managing state across long-running loops.
Fugu abstracts this operational overhead entirely. It is essentially a LangGraph-style workflow packaged as a single, black-box API endpoint.
An orchestration system is ultimately bounded by the raw capabilities of the underlying models in its pool, a reality reflected in Sakana’s own benchmark testing against standalone frontier models.
On rigorous coding and agentic tasks, collective intelligence shows a distinct advantage over standard models. Fugu Ultra posted a 73.7 on SWE-Bench Pro, significantly outperforming Anthropic’s Claude Opus 4.8 (69.2) and OpenAI’s GPT-5.5 (58.6).
However, Fugu is not a silver bullet, and its performance is not a clean sweep across the board. When compared to highly specialized or restricted-access monolithic models, Fugu occasionally trails:
SWE-Bench Pro: While Fugu Ultra (73.7) beat most accessible models, it was comfortably eclipsed by Anthropic’s limited-access Fable 5 (80.0), which is currently absent from Fugu’s swappable pool due to the U.S. government’s export control order and Anthropic’s subsequent response to remove the model entirely from global usage.
Humanity’s Last Exam: Fugu Ultra (50.0) narrowly edged out Opus 4.8 (49.8), but again fell short of Fable 5 (53.3).
Long-Context and Security: On the MRCRv2 long-context-recall test, OpenAI’s GPT-5.5 maintained the lead (94.8 vs Fugu Ultra’s 93.6), and Opus 4.8 remained the top performer on the CTI-REALM cybersecurity benchmark (69.6 vs Fugu Ultra’s 69.4).
The quantitative data points to a clear conclusion: Fugu is highly effective at boosting performance on messy, multi-step tasks (like writing a complex HTML5 game from scratch) by leaning on the combined strengths of multiple mid-tier and high-tier models.
However, for sheer brute-force reasoning within a single, highly constrained domain, the industry’s largest standalone models still hold the edge—provided an enterprise can maintain uninterrupted access to them.
Sakana AI was formed in Tokyo in 2023 by Llion Jones, a co-author of Google’s foundational 2017 “Attention Is All You Need” paper, and David Ha, the former head of research at Stability AI.
Disillusioned by large tech company bureaucracy and the industry’s hyper-fixation on scaling single, massive foundational models, the founders built Sakana around principles of biomimicry and evolutionary computing.
The company’s name, derived from the Japanese word for fish, reflects its core technical thesis: utilizing collective “swarm” intelligence rather than brute-force compute. Following a $2.6 billion Series B valuation in late 2025 and the recent June 2026 launch of Marlin—an autonomous, eight-hour research agent for the B2B sector—Fugu represents the commercialization of Sakana’s multi-agent routing technology for everyday developers.
The developer community has responded to Fugu by rigorously testing its practical tradeoffs, weighing its routing efficiencies against the sheer power of monolithic foundation models.
AI observer, developer and influencer Chris (@ChrissGPT on X) highlighted the specific utility of Fugu over raw foundational AI.
“For a single clean prompt, you probably would [use Fable 5, Mythos, or GPT-5.5 directly],” he noted, but argued that Fugu’s true value emerges in messy, multi-step environments. “…whether it involves delegation, verification, synthesis, code review, research loops, security analysis… the more it would make sense to use this,” he wrote.
Chris also pointed out the strategic geopolitical advantage of Fugu’s architecture, noting that if frontier AI access is abruptly revoked due to regulation or export controls, an orchestrator can dynamically swap models to prevent a total system failure.
Creative agency owner Mark Santos (@markksantos) of Mark Studios provided a direct, real-world comparison by tasking both Fugu Ultra and Claude Opus 4.8 with building a “Crossy Road” game clone using Three.js. The results underscored the operational differences between an orchestrator and a monolithic giant:
Sakana Fugu Ultra: Completed the task in 22 minutes using ~89,000 tokens for roughly $7.32. However, the final game suffered from minor logic errors, such as inverted directional turns and wonky camera angles.
Claude Opus 4.8: Took 79 minutes, burned ~940,000 tokens for nearly $37.85, and got stuck in a retry loop requiring human intervention. Despite the inefficiency, it ultimately produced superior application design and functionality.
Santos concluded the experiment by stating, “In terms of application functionality, quality, and design, Opus won. In terms of model speed and performance, Fugu… won”.
Elie Bakouch, a research engineer at cloud-based, open AI infrastructure and systems provider Prime Intellect, pointed out on X that “to be clear, this is a closed source orchestrator on top of closed source models. if before you didn’t control the models, now you don’t even control which ones are used or how much. this is not ‘AI sovereignty’…”
These early tests and reactions mirror the sentiment summarized by Reddit user GreedyWorking1499 in initial platform discussions: “Until proven otherwise, this is just a highly advanced router/wrapper, not a fundamental not a fundamental leap in intelligence like Mythos/Fable was.“
Yet, as enterprises increasingly demand fail-safes against single-vendor reliance, Sakana is proving that packaging collective intelligence into a single API endpoint is a highly viable commercial path.

Not every company can or should build their own frontier AI language model. However, the harness controlling the model is something that most enterprises can and should customize for their specific purposes.
Of course, this is easier said than done. Agent harnesses are still largely tuned through manual, ad hoc debugging — a process that relies heavily on intuition rather than systematic feedback loops, making it difficult to keep pace with rapidly evolving LLMs.
To solve this challenge, researchers at the Shanghai Artificial Intelligence Laboratory have introduced “Self-Harness,” a new paradigm in which an LLM-based agent systematically improves its own operating rules. By examining its own execution traces to apply edits, the system trades manual guesswork for empirical evidence.
Self-improving harnesses can enable development teams to deploy robust custom agents that continually adapt their own execution protocols to overcome model-specific weaknesses.
An LLM-based agent’s performance is not determined solely by its underlying base model, but also by its harness: the surrounding system that provides context and enables the model to interact with the environment. A harness includes components like system prompts, tools, memory, verification rules, runtime policies, orchestration logic, and failure-recovery procedures.
This layer is crucial because many common agent failures stem from the harness rather than the model. For example, an agent may report success without checking the model’s response (e.g., running the code to see if it passes the tests), or it might retry a failed action repeatedly. The harness is also responsible for preventing context rot or overload when the agent’s interaction history grows very large. Examples of popular harnesses include SWE-agent, Claude Code, Codex, and OpenHands.
Harness engineering remains a significant challenge, but the bottleneck isn’t necessarily that humans are too slow or incapable.
In fact, Hangfan Zhang, lead author of the Self-Harness paper, told VentureBeat that “in many cases, an experienced engineer with deep domain knowledge can still propose better changes than an LLM can today.”
Instead, the true bottleneck of manual engineering is that it relies heavily on ad hoc debugging rather than a verifiable, empirical feedback loop. “The deeper issue is that the current harness-engineering paradigm often lacks a systematic feedback loop,” Zhang explained. “Many edits are made based on intuition, a few observed failures, or ad hoc debugging.”
With new models being released at a rapid pace, depending on human intuition to manually tune model-specific harnesses becomes increasingly costly and untenable. While some approaches use stronger models to improve the harnesses of weaker target agents, this dependence on external guidance has its own challenges, as these models may be costly, unavailable for frontier models, or mismatched to the target model’s failure modes.
The Self-Harness paradigm enables an LLM-based agent to improve its own harness without relying on human engineers or stronger external models.
This continuous self-evolution is driven by a three-stage iterative loop that turns behavioral evidence into harness updates:
Weakness mining: Starting from an initial harness, the agent runs a set of tasks, producing execution traces with verifiable outcomes. The agent categorizes failed traces and tries to detect model-specific failure patterns.
Harness proposal: Based on these failure patterns, the agent uses a “proposer” role to generate a set of diverse yet minimal harness modifications, each tied to a specific failure mechanism to avoid overly general corrections.
Proposal validation: The system evaluates candidate modifications through regression tests. An edit is promoted only if it improves performance without causing measurable degradation on held-out tasks. If multiple candidate modifications pass the regression tests, they are merged into the next version of the harness, which then serves as the starting point for the next iteration.
To visualize why an enterprise would need this, imagine an automated issue-fixing agent that reads internal documentation, writes patches, and opens pull requests. If the company updates its documentation style, the agent might suddenly fail, pulling the wrong context or writing bad patches.
On the surface, the agent simply looks broken. But Self-Harness turns this ambiguous failure into a solvable problem. “The failure traces expose where the agent is misusing the new documentation format; the proposer can generate a targeted harness edit… and the evaluator can decide whether that edit improves the failing cases without regressing other cases,” Zhang said.
The researchers evaluated Self-Harness on Terminal-Bench-2.0, a benchmark that tests general tool-based execution, including artifact management, command use, verification behavior, and recovery from execution errors. They applied Self-Harness with MiniMax M2.5, Qwen3.5-35B-A3B, and GLM-5.
To isolate the impact of the self-evolving harness, they started with a minimal harness built upon the DeepAgent SDK, containing only the benchmark-facing system prompt, and the default filesystem and shell tools. The model backend, tool set, benchmark environment, and evaluator were kept unchanged while only the harness was allowed to vary.
The quantitative results show that agents improved their performance through automated harness edits. On held-out tasks, performance jumped significantly across the board, ranging from 33 to 60 percent relative improvements for different models.
Importantly, an explicit acceptance rule promotes only those edits that improve performance without introducing unacceptable regressions. What makes Self-Harness powerful for enterprise applications is that it doesn’t simply make the prompt longer or add generic instructions. Instead, it introduces targeted changes that reflect the recurring problems each model encounters during execution.
For example, under the baseline harness, MiniMax M2.5 would get stuck endlessly exploring dataset configurations until the execution environment timed out, failing to produce any deliverables. Through Self-Harness, the system identified this specific flaw and wrote a “loop breaker” into its runtime policy, forcing the agent to stop and redirect its approach after 50 tool calls. It also added a rule to create an initial version of required artifacts as early as possible.
On the other hand, Qwen-3.5 had a habit of hitting a file overwrite error and then blindly retrying the same command repeatedly, eventually deleting necessary files out of confusion before stopping. The self-harness fixed this by introducing a strict command-retry discipline (forbidding exact duplicate commands) and a mechanism that forced the agent to immediately recreate any missing artifacts if a file error occurred.
GLM-5 struggled to preserve environment changes across different commands, and would often waste time on massive downloads or finalize tasks even when sanity checks were failing. Its self-generated harness introduced rules instructing the agent to persist PATH variables across shell sessions, limit external compute, and repair any failed sanity checks before concluding its run.
While Self-Harness automates the tedious work of tracking down idiosyncratic model failures, decision-makers must be realistic about the trade-offs. Replacing human engineering with automated trial-and-error requires significant computational overhead.
“Self-Harness replaces part of the human engineering burden with repeated proposal generation, parallel candidate evaluation, and regression testing,” Zhang said. “That can mean more API tokens, more latency during optimization, and more infrastructure for running evaluation tasks.”
Also, this system relies on the accuracy of its evaluation pipeline. During their experiments on Terminal-Bench-2.0, the researchers relied on strict, deterministic verifiers to ensure the agent’s edits were actually helpful. Without this rigorous ground truth, an automated system risks promoting bad updates. “[The] evaluation system is not an optional component; it is what lets us trade human intuition for empirical evidence,” Zhang said.
This reliance on strict verifiers also dictates where Self-Harness should be deployed. “The best deployment targets today are environments where failures can be measured and where trial-and-error is relatively safe,” Zhang said, pointing to coding, internal workflow automation, and DevOps data pipelines as ideal use cases.
Conversely, enterprises should avoid fully automating harnesses in high-stakes or subjective fields. “The clearest red flags are domains where evaluation is subjective, delayed, non-deterministic, or costly to get wrong, such as medical decision-making, safety-critical infrastructure, or legal decisions.”
The introduction of self-improving agents does not mean coding or enterprise workflows will suddenly become human-free. The quality of collaboration between the human engineer and the AI is still paramount and difficult to capture with automated benchmarks.
Instead, the engineering profession is moving up the abstraction layer. “The role of enterprise engineers will shift from manually patching individual prompts or tool calls toward designing the feedback systems that make agent improvement possible,” Zhang predicted. Moving forward, “the engineer becomes less of a prompt tweaker and more of a feedback architect.”
As foundational models grow more capable, they will naturally absorb many capabilities that currently require manual harness engineering. “But once that happens, the harness will not disappear; its scope will move outward to connect the model to richer external environments,” Zhang said. “Until that boundary moves beyond what humans can evaluate, humans will remain critical providers of feedback.”

As inference workloads evolve from discrete question-and-answer exchanges into persistent, multi-step agentic systems, GPU availability is no longer the most critical AI bottleneck. Instead, the bottleneck has migrated from compute to context, says Jeff Harthorn, AI applied research lead at Solidigm.
“Why context management has become a primary bottleneck, more than GPU availability or compute efficiency, is the question of 2026,” says Harthorn. “GPUs have gotten dramatically cheaper per FLOP. Model architectures and inference serving engines have all gotten much more efficient. But the thing that’s grown faster than both of those is context. The persistent state that has to live between sessions has grown even faster than context itself.”
It’s happening as context windows grow dramatically, making individual inputs far larger than before. Agentic AI systems chain dozens or hundreds of model calls together, each generating state that must be tracked, and enterprises are requiring that inference state persist across sessions for audit, governance, and reuse. These trends compound each other, pushing context volumes beyond what any existing memory tier was designed to handle.
“Those three things are all happening at the same time, all of which are pushing context data and context memory into the stratosphere much more quickly than we’re used to seeing,” adds Ace Stryker, director of AI and ecosystem marketing at Solidigm.
The solution is a dedicated context tier emerging between GPU memory and bulk network storage: a layer of high-performance, high-density flash designed specifically to hold and serve Key-value (KV) cache, the inference data that allows models to retain and reuse context, and retrieval data at inference speed. Nvidia has formalized this architecture under the term CMX. Storage companies including Solidigm are building SSD products optimized for this workload.
“Storage has not been the first thing folks have thought about when they’ve been planning their enterprise infrastructure buildout,” Stryker says. “In a lot of ways, it was a relatively small cost compared to compute, and it was a commodity. You just shopped around for the lowest dollar per gigabyte and called it good. But now, if your storage is not up to snuff, your ROI suffers, and it directly impacts your bottom line.”
The storage architecture that AI systems rely on today was largely inherited from training workflows. Training is sequential and write-dominated, with data moving in large blocks to and from bulk object storage. The tier structure, with high-bandwidth memory on the GPU, fast NVMe in the server, and bulk storage over the network, serves that use case reasonably well.
However, inference is a different animal. Its I/O signature is fine-grained, latency-sensitive, and increasingly stateful. KV cache data and retrieval data each have distinct access patterns, but both need to be served quickly and reused across interactions. Neither fits cleanly within GPU high-bandwidth memory, which is expensive and physically constrained, nor within traditional bulk storage, which was never designed for active inference workloads.
“The architectural gap that’s interesting to me right now isn’t at the top of the stack or the bottom, it’s right in the middle,” Harthon says. “A lot of what sits below the GPU HBM is being asked to do things it wasn’t really designed for, which is where the most interesting systems work today is happening.”
One of the most visible symptoms of this gap is recomputation. In inference, the pre-fill stage processes all of the context relevant to a given session before token generation can begin. When KV cache state isn’t available in a fast, accessible tier, the system recomputes it — burning GPU cycles that produce no new value.
“A meaningful share of GPU cycles end up going to re-pre-filling,” Harthon explains. “During all of that calculated context, that’s potentially compute that’s being spent reproducing state, rather than doing new work. When you start looking at the problem that way, GPU utilization starts looking like it’s partly a storage problem.”
This reframing is driving renewed interest in a metric borrowed from networking: goodput, or useful tokens per dollar, rather than raw tokens per dollar.
The industry’s response is taking structural form. A new tier is emerging between GPU memory and traditional network storage, designed specifically to hold and serve inference context, a layer distinct from drives inside GPU servers (G3) and storage servers over the network (G4), engineered to serve context data back to accelerators as rapidly as possible.
“If you’re building a data center starting in the second half of this year, or the beginning of next year, you can’t think about storage only living in two places,” Stryker says. “Storage has to live in at least three places to handle the context memory tier, and that’s likely to be a permanent fixture in how the infrastructure gets built going forward.”
It’s analogous to the emergence of object storage as a category, which didn’t exist until enough workloads needed it. And once it did, it developed its own primitives, SLAs, cost models, and an ecosystem of vendors.
“The context tier looks like it might be on a similar arc,” Harthorn says. “That volumetric pressure is causing the category to form, rather than any one vendor’s road map.”
For infrastructure leaders, this means actively planning for the new tier rather than treating it as optional. Deploying additional NAND at this layer reduces dependency on DRAM, which is orders of magnitude more expensive per gigabyte and constrained in both availability and thermal headroom.
“In terms of your investment effectiveness, you’re laying out less cash to do it if you rely on the SSD layer in the way that Nvidia is now recommending and prescribing for a lot of use cases,” Stryker adds.
Participating meaningfully in the inference stack places new demands on SSD technology. Tail latency, the worst-case performance of a drive, must be predictable, not just fast on average. An orchestration system that allocates GPU resources based on expected storage response times cannot tolerate unexpected multi-second delays. Consistent, observable performance matters more here than peak throughput.
Beyond latency, density becomes a critical concern, especially at hyperscale. In data centers where power, not cost, is the binding constraint, watts per petabyte becomes the operative metric. Floating gate NAND, the manufacturing approach at the core of Solidigm’s products, is suited to that calculation. Network integration via NVMe over Fabrics, RDMA, and eventual CXL support is also essential, given the tight latency budgets of active inference pipelines.
“The drives have to have reliable performance characteristics, beyond the throughput side and being able to transfer as much data as possible as fast as possible, the way that training needed,” Harthon says. “Now it’s about being able to do it very consistently, in a way that’s very observable to the people operating and orchestrating these systems.”
The standards, software primitives, and best practices being established now will define how AI inference infrastructure operates for years to come. Solidigm is engaged in that process through standards bodies, partner lab collaborations, and published research, which is critical precisely because the category is still forming.
“The interesting question for the next couple of years isn’t whether AI infrastructure needs more compute,” Harthorn says. “It’s whether it can use what it has more efficiently. A lot of that answer runs through this tier that is being built today.”

Enterprise teams keep watching the same thing happen. An AI agent demos beautifully, goes to production, and stalls: it runs for a short stretch, then needs a human to top up its context and check its output, and the promised efficiency drains into supervision. The agent did the work; you did the watching. It’s one reason so many agent pilots never turn into production systems.
The pitch on the other side of that wall is the one every team wants to believe: an agent that runs a long job on its own, overnight if it has to, and leaves a person to validate only the last 10%. Whether that is achievable turns on a problem the orchestration conversation mostly skips. When AI firm Chroma tested 18 leading models, every one lost accuracy as its input grew, a property of how attention works, not a gap a stronger model closes. An agent fed more and more of your business as it runs does not get steadier. It gets shakier.
This is the layer beneath the orchestration race. Routing, durable execution and observability all assume each agent is already competent enough to coordinate in the first place. The deeper question is how long an agent can run before a human has to step in, and that comes down to where your company’s knowledge lives relative to the model. Both standard fixes leave a human in the loop.
Frontier models keep getting more capable, and the gap does not close, because it is not a capability problem. It is about where your knowledge sits relative to the model, and enterprises have had two ways to place it there.
The first is fine-tuning, which bakes knowledge into the weights. It remains subject to catastrophic forgetting, a problem identified in the 1980s and still unresolved in 2026: teaching a model something new tends to erode what it already knew. Teams work around it by isolating each task in its own fine-tuned model or adapter, which produces a sprawling estate of models that raises cost and governance overhead. And a fine-tuned model is a snapshot, stale the day a policy changes, when the expensive, slow retraining cycle starts over.
The second is in-context learning, which skips retraining by placing the relevant policies in the prompt at run time. This is where context rot bites. Retrieval narrows what goes into the prompt, but a retrieval miss looks identical to a confident answer, and both cost and latency climb with every token added.
The two failures rhyme. With fine-tuning, the model can be confidently working from last quarter’s policy. With in-context learning, it can be confidently working from a detail it lost in the middle of a long prompt. Either way the output looks equally assured, so you cannot tell which parts are wrong without checking all of them. That is why the human never gets to leave. Some teams often run both at once, fine-tuning the stable knowledge and retrieving the rest. That softens each failure but removes neither: on any given output you still cannot be sure the model is both current and working from the right context, so you still check it.
A third approach is moving from research into early product. Instead of retraining one model or stuffing its prompt, a generator builds a small, task-specific model on demand from your policies, at inference time. The generator is a hypernetwork: a network whose output is the weights of another network.
The idea was named in 2016; applying it to produce specialist language models from text or documents is recent and active. Sakana AI’s Text-to-LoRA, presented at ICML 2025, generates a model adapter from a plain-language description in a single pass, and a 2026 system called SHINE calls hypernetwork adaptation a promising new frontier, precisely because it sidesteps both the retraining cost of fine-tuning and the context limits of prompting.
The point of generating adapters rather than training and storing them is to collapse a sprawling library of per-task LoRAs into one network that can produce them on demand, including for tasks it has not seen.
The elegant part is how this closes the loop on the problem above: the per-task adapter teams hand-build to dodge catastrophic forgetting is the same object a hypernetwork produces automatically. The model zoo stops being a governance headache and becomes a generated output.
The case for going small underneath all this was put most directly in a 2025 paper by Nvidia researchers: for the narrow, repetitive tasks that fill agent workflows, small models are capable enough and 10 to 30 times cheaper to run than frontier generalists. Nace.AI, a Palo Alto company that raised a $21.5 million seed round in May, is the clearest commercial instance. Its core technology, a generator it calls a MetaModel, produces parameter adaptations for a model at inference time from a company’s policies, pointed at regulated work: audit, compliance, risk assessment. The company says its agents handle the bulk of a workflow while human experts validate the result, a split it markets as 90/10.

A model that is narrow, current and small has a smaller surface on which to be wrong. Fewer errors, confined to a known domain, mean fewer outputs an agent has to escalate to a person, which is the real basis for any high-autonomy claim. It is also where a number like 90/10 comes from: not a dial set in advance, but an outcome of how little the system needs to hand back. Reported autonomy shares are best read as measurements of an architecture, not as settings.
Two design choices decide whether that autonomy is trustworthy or merely fast. The first is grounding: tying every output to its source so a reviewer can verify rather than redo. Research models built for exactly this, such as HalluGuard, label each claim as supported or not and cite the passage they relied on. Nace ships its agents with grounding models and reasoning traces for the same reason. A 10% review only means something if the human can confirm provenance in seconds.
The second is the feedback loop, and it forces a question every buyer should ask: when your experts validate the output, whose model improves, and where does it live? That decides whether the compounding asset belongs to the vendor or to you. Arrangements differ. Nace, for instance, uses an external network of certified experts for some engagements and, for direct enterprise deployments, the customer’s own staff, with the resulting model kept inside the customer’s cloud. Each choice routes the learning, and the ownership, somewhere different.
The approach is still early, and a few questions will decide how far it goes. Calibration is the linchpin: the value rests on the model knowing when it is unsure. And it is genuinely unsettled, recent work generating these adapters found they do not automatically improve calibration over ordinary fine-tuning, with gains appearing only under specific constraints.
The quality of the generated model also depends heavily on the policy data it is built from, which puts a premium on data curation. And scale is the open research frontier, the hypernetworks shown in published work so far have been small. This is where Nace’s own work gets interesting: in our interview, the company said it has scaled its generator well beyond those published sizes and derived a scaling law for how performance grows, results it has begun to share publicly and is now putting through peer review. If it holds up, it would help answer one of the central open questions in the field, and it is the paper worth watching.
Whichever approach wins, the work still ends at a human, and that handoff is its own design problem. When Deloitte Australia delivered a roughly A$440,000 government report, it shipped with fabricated citations and an invented court quote after passing senior review, because the reviewers checked the conclusions, which were sound, and not the provenance, which was not. Controlled research suggests the pattern is general: experts corrected an identical flawed recommendation less often when it was labeled AI-generated.
The EU AI Act’s Article 14 now names this automation bias. The lesson is not about any one vendor: a high autonomy share concentrates human attention into a thin, late slice of the work, so the value of that review depends entirely on whether the human can check provenance fast, which loops back to grounding.
The honest takeaway: what holds your agents back is usually not orchestration or model size, but whether the model knows your business well enough to be left alone, and the right fix depends on the job. To automate a long, repetitive, high-volume process end to end, run most of your internal audit overnight and have your own experts check the final slice, a hypernetwork generated model is the approach most likely to do it cheaply and run long enough to matter. For a short task that finishes in a few steps and never needed to run unattended, the gap between this and a well-prompted frontier model shrinks to almost nothing, and is not worth the integration cost.
When a vendor pitches autonomous or specialist agents, four questions cut through it.
Where does the business knowledge live: in the weights, the prompt, or generated on demand?
What does each output come with, so a reviewer can verify it instead of redoing it?
What decides which work gets escalated to a human?
And whose model improves from that feedback, and where does it run?
The answers, not the headline ratio, tell you what you are buying.
The hypernetwork approach is the most credible attempt yet at making a small model know a specific business without forgetting it and without re-explaining it on every run. It is also the least proven, and the parts that matter most, calibration and scale, are still in peer review. For the right job, pilot it now. For the wrong one, the integration cost buys you little that a well-prompted frontier model wouldn’t.
Imagine your engineering team just deployed an AI agent to search through internal company documents and answer employee questions. It works perfectly in development, but in production, it consistently hallucinates or misses key constraints. Fixing this is rarely a simple patch. It requires a tedious, trial-and-error process of tweaking chunking strategies, retrieval methods, and system prompts simultaneously. Because these adjustments are entangled, it becomes nearly impossible to attribute which specific tweak actually solved the problem.
To address this challenge, researchers at Renmin University of China and Microsoft Research introduced Arbor, a framework that upgrades AI-driven research and optimization from a sequence of trial-and-error guesses into a cumulative learning process. Arbor organizes hypotheses, experiments, and insights into a tree that helps the system learn from prior failures to make smarter, verified improvements over time.
In practical tests, Arbor delivered more than 2.5 times the verifiable performance gains of standard AI coding agents across real-world engineering tasks while operating under the same resource budget.
For enterprise AI, this technique directly translates to automating the continuous improvement of complex, real-world engineering systems.
As large language models and AI systems become more capable, they are expected to carry out more complex operations such as autonomous optimization (AO) of software systems such as agent harnesses or model training algorithms.
AO captures the fundamental loop of autonomous research. An AI agent starts with an initial mutable artifact, such as a machine learning codebase or data pipeline, and a specific objective. The agent’s goal is to iteratively improve this artifact through experimental feedback without step-by-step human supervision.
The main challenge of AO is often misunderstood. Many engineering teams find that simply giving a coding agent more time or compute to optimize a codebase doesn’t lead to better results. “Automation can keep an AI working for a very long time — but a loop is not the same as progress,” Jiajie Jin, co-author of the paper, told VentureBeat. “If the goal is vague, or the metric is easy to hack, long-running automation often just produces ‘improvements’ faster that nobody actually wants.”
Jin explains that complex tasks take many attempts to get right, and standard agent architectures are missing the critical data structure to maintain state. “How do you make sure the insight and experience from each attempt actually accumulate, instead of getting lost in a scrollback buffer?” he said. Without this structure, agents simply repeat the same mistakes.
Current agent systems can run experiments for many hours against well-specified goals: editing code, invoking tools, running tests autonomously. But they treat each attempt in isolation, missing the structural mechanisms that would let them accumulate and act on what they’ve learned.
They lack the capacity to simultaneously maintain and compare multiple competing research directions. Without this, they cannot interpret both successes and failures to reshape their future exploration, which is the core mechanism that makes human research cumulative.
General coding agents typically rely on conversation transcripts for their memory. Because AO tasks span hundreds of turns and easily exceed context window limits, these agents struggle to preserve and reuse factual evidence over long histories. As a result, they lose the overarching structure of the research process and are prone to stalling on early failures or chasing noisy evaluation swings. The system needs a structured, durable memory that records what directions have been tried, what factual evidence was produced, and how each result changes the space of future hypotheses.
Existing frameworks are also prone to reward hacking and overfitting to development metrics. This makes them create the illusion of progress without producing improvements that transfer to real-world performance.
Finally, general-purpose coding agents typically chain their tool calls on a single shared working tree. This architectural limitation prevents them from testing parallel hypotheses in isolated environments without corrupting the main codebase or obscuring which hypothesis caused a specific outcome.
Arbor solves the challenges of AO with a framework that automates the long-horizon loop of exploration, experimentation, and abstraction that characterizes human research. Arbor separates the strategic direction of research from the ground-level coding tasks with two key components:
The coordinator: A long-lived AI agent that acts like a principal investigator. It never directly edits the target codebase. Instead, it owns the general state of the optimization research, observes accumulated evidence, comes up with new hypotheses and directions to explore, and decides what to do with the results of experiments.
Executors: Short-lived, highly focused AI agents. When the coordinator wants to test an idea, it spins up an executor and places it in an isolated environment, essentially a fresh git worktree. Each executor is handed one hypothesis. It implements the assigned idea, runs evaluations, debugs errors, and reports back to the coordinator with the results and created artifacts.
These two components collaborate through a mechanism that the researchers call “Hypothesis Tree Refinement” (HTR). HTR represents the entire research process as a persistent, branching tree where every node binds together four things: a hypothesis, the executable artifact, the factual evidence produced, and a distilled insight. This means the coordinator can explore multiple competing directions at the same time without losing its place.
The coordinator builds the tree by placing broad ideas near the root, while concrete refinements branch out as leaves. This allows Arbor to safely explore multiple competing hypotheses simultaneously. If an executor’s experiment fails, the tree records why it failed as a negative constraint, ensuring the system doesn’t endlessly repeat the same mistake.
To understand why Arbor’s isolation matters, consider a common enterprise scenario: optimizing a Retrieval-Augmented Generation (RAG) pipeline for an internal AI assistant. “When you ask a single agent like Claude Code or Codex to ‘improve accuracy,’ it will typically change a bunch of things in one pass — chunking, the prompt, the retrieval method,” Jin said. This entangles the changes, making it impossible to attribute which one actually helped. It also directly mutates the repository without isolation.
Arbor solves this by treating each lever as a separate hypothesis. Chunking becomes one branch, retrieval another, and the prompt another — each implemented and evaluated in its own isolated git worktree. “So you get clean attribution: ‘constraint decomposition on the retrieval side gave +X; breadth-first search actually hurt,'” Jin said.
When an executor returns a report, the coordinator writes the evidence to the tree and backpropagates the insight upward to parent nodes. This means a local observation becomes a generalized constraint that shapes the coordinator’s future idea generation.
To prevent reward hacking or overfitting to the development data, HTR enforces a strict “merge gate.” Even if an executor reports a fantastic development score, the coordinator will spin up an isolated worktree to test the candidate against a held-out test evaluator. The artifact is only merged into the current best trunk if it demonstrably improves the test score, verifying that the progress is real.
Arbor generally falls under the concept of “loop engineering,” popularized by industry figures like OpenClaw creator Peter Steinberger and Claude Code lead Boris Cherny. The idea is to move beyond single prompts to design iterative cycles (observe, reason, act, verify) that drive autonomous agents. However, as Jin points out, “A loop can fill up with messy, untraceable attempts, and you end up with nothing to show and no way to reconstruct what changed.”
The researchers evaluated Arbor on an autonomous optimization task suite built from real-world research settings and the MLE-Bench Lite machine learning engineering benchmark. The AO suite featured tasks from different areas of AI development, including model training, harness engineering, and data synthesis.
The researchers used different backbone models for the coordinator and executor agents, including Claude Opus 4.6, GPT-5.5, and Gemini-3-Flash. They tested Arbor against the strongest coding agents, Codex and Claude Code. Arbor and the baselines were given the same resources. For the MLE-Bench Lite tasks, Arbor was also compared against top-tier agentic research systems like AI-Scientist, ML-Master, and AIDE.
Arbor consistently outperformed the baselines. It achieved the best held-out test result on all tasks, attaining more than 2.5 times the average relative gain of Codex and Claude Code. On the BrowseComp task, which involves optimizing a search agent, Arbor improved the system’s held-out accuracy from a baseline of 45.33% to 67.67%. Meanwhile, Codex and Claude Code stalled at 50% and 53.33%, respectively. On MLE-Bench Lite, when equipped with GPT-5.5, Arbor achieved the strongest result among all benchmarked systems.
Arbor proved to be resilient against overfitting. For example, during the Terminal-Bench 2.0 task experiments, Claude Code achieved a high development score of 75 but its score dropped to 71 on the held-out data. Arbor had a lower development score of 72.22 but achieved the highest held-out score of 77.36, ensuring its results transfer to real-world applications.
Arbor also showed generalization in a cross-task transfer experiment. After Arbor finished optimizing the search harness for the BrowseComp task, researchers took the optimized codebase and tested it on two unrelated search-agent tasks, HLE and DeepSearchQA. Arbor’s optimized codebase significantly improved performance on those unseen tasks as well.
For engineering leads looking to drop Arbor into their existing tech stack, the framework is designed to sit on top of existing Git workflows rather than replacing them. “Its output is an ordinary git branch that your existing code review, CI, and human review can inspect directly,” Jin said. Only verified gains are merged into a per-run trunk, leaving the main repository untouched until a developer manually chooses to promote the code.
However, deploying Arbor comes with specific tradeoffs. Jin points out that the biggest catch is token cost, as maintaining a long-lived coordinator that continuously manages the tree and dispatches executors is the dominant expense. Running multiple isolated worktrees concurrently also requires genuine compute and disk resources to process real experiments.
So where is Arbor’s sweet spot? According to Jin, it excels at tasks with a clear, trustworthy metric, tolerance for a long time horizon, and a real search space with several plausible directions, such as pipeline optimization, data-synthesis quality, and model-training recipe tuning.
Conversely, teams should explicitly avoid using Arbor for real-time latency tasks, obvious one-line fixes, or when the underlying evaluation metric is flawed. The quality ceiling of the entire run is strictly bounded by the quality of the evaluator. “If the metric isn’t trustworthy, Arbor will just optimize toward an untrustworthy result faster,” Jin said.
Jin sees the next evolution going beyond single scalar metrics. “A natural evolution is to have each node’s artifact carry a vector — accuracy, latency, cost — instead of a single score,” Jin said. “Going from a single scalar to a multi-objective Pareto search is a very natural extension of the framework.”
Adobe has announced a major expansion of its “creative agent” across its flagship Creative Cloud suite and upgraded Firefly AI studio.
Available in public beta starting today across Premiere Pro, Photoshop, Illustrator, InDesign, and Frame.io, the agent is designed to serve everyone from individual creators to enterprise marketing teams.
Unlike first-generation generative AI tools that simply output flat media from a chat interface, Adobe’s embedded assistant acts as an orchestration layer.
It interprets natural language prompts and directly accesses the underlying software’s APIs to execute complex, multi-step production workflows—from batch-renaming video sequences to dynamically updating brand assets across print layouts—while leaving the final aesthetic decisions entirely in the hands of the human designer.
At the core of this release is a significant technical upgrade to how Adobe’s AI handles persistent memory and context window management. In its upgraded Firefly creative AI studio—currently in private beta—Adobe has introduced two foundational architectural components: “Elements” and “Projects”.
Elements functions as a visual variables library, allowing users to save and reuse specific characters, locations, and objects across multiple generations to ensure strict visual consistency as campaigns scale.
Projects acts as the contextual memory layer, storing assets, generations, and session history in a unified space so users can pick up where they left off without rebuilding their prompt context.
Beyond pixel generation, the system’s most critical technological leap is its ability to operate seamlessly within the complex document structures of desktop applications. “Our Adobe Creative Agent can leverage the decades of powerful features, workflows, APIs that we’ve brought into our application and exposed through tooling that can now be invoked through a creative agent,” an Adobe representative explained.
The practical application of this technology fundamentally alters standard production workflows. Adobe is positioning the human user as a “creative director” capable of delegating repetitive, labor-intensive tasks to the AI. The rollout introduces highly specific specialist agents tailored to the logic of each application:
Premiere Pro: The agent handles tedious project setup, analyzing and sorting source media into bins, batch renaming clips, identifying interview questions, and assembling a rough working starting point.
Illustrator: The assistant automates mathematical and multi-step design tasks, such as generating 50 versioned files from a spreadsheet or running pre-flight checks to flag color mode errors before printing. It can even programmatically duplicate a vector shape 100 times, randomize its position, and change its size based on its z-depth and transparency.
Photoshop & InDesign: The agent executes batch background removals, dynamic layer organization, and applies brand updates across multi-page layouts.
Furthermore, Adobe is actively integrating its creative agent into major third-party enterprise platforms, including OpenAI’s ChatGPT, Anthropic’s Claude, Microsoft 365 Copilot, and soon, Google Gemini and Slack.
Unlike open-source orchestration frameworks or models released under MIT or Apache licenses, Adobe’s creative agent operates strictly within a proprietary, commercial SaaS ecosystem. For enterprise decision-makers, this carries specific implications. Because the agent relies on Adobe’s proprietary APIs to manipulate project files, it requires an active Creative Cloud commercial license. Additionally, by bringing the “Adobe for creativity connector” to platforms like Slack and Microsoft Copilot , enterprise IT and systems architects must consider how internal chat tools will interface with Adobe’s cloud processing environments to support enterprise creative and marketing teams securely.
While Adobe’s announcements highlight a powerful user interface and deep integration within its own flagship applications, several critical questions remain for enterprise technical decision-makers tasked with building bespoke AI systems. VentureBeat has reached out to Adobe for clarification on these infrastructure-level details and will update this coverage as we learn more.
For AI system architects, the value of a creative agent lies not just in a native application UI, but in its extensibility. It remains unclear if Adobe plans to expose these new agentic capabilities via API, or if the company will support the Model Context Protocol (MCP). Without MCP support or direct API access, enterprise teams will face friction integrating Adobe’s tools into their own custom task-routing frameworks and internal LLM pipelines.
Adobe’s new “Elements” feature promises to solve the generative AI consistency problem by anchoring characters and objects across generations.
However, the backend architecture driving this persistent memory is not yet detailed. Whether Adobe is leveraging on-the-fly Low-Rank Adaptation (LoRA) based on user uploads or utilizing a form of visual Retrieval-Augmented Generation (RAG) is a critical distinction for technology leaders managing compute costs, model evaluations, and enterprise-grade inference pipelines.
As organizations build out “Projects” and define brand-specific “Elements”, security and data decision-makers require strict guarantees regarding data provenance and storage. It is currently unknown exactly where this contextual workflow and vector data lives—specifically, whether it remains strictly sandboxed within the customer’s enterprise Creative Cloud instance on Adobe servers, and how role-based permissions apply to these new agentic workflows.
Finally, as lightning-fast, developer-first, multi-model AI creative platforms like fal.ai gain significant traction among enterprises and developers, Adobe’s position in the broader developer ecosystem remains a point of interest.
Whether Adobe views these infrastructure-level API providers as direct competitors to its Firefly AI studio or as potential integration points for bespoke enterprise environments has yet to be seen.
The integration of agentic AI touches on the tension between eliminating drudgery and surrendering creative control. According to Adobe’s recent Creators’ Toolkit Report, which surveyed over 16,000 creators globally, the market is highly receptive to AI as an operational assistant rather than an autonomous creator.
75 percent of surveyed creators describe creative AI as integrated or essential to their current workflows.
85 percent emphasized that the final creative decision must always remain in human hands.
This sentiment is central to Adobe’s messaging. By focusing the agent’s capabilities on file organization, layer management, and brand compliance, Adobe aims to automate what a spokesperson called the “tedious parts of their workflow”. The goal, according to Adobe executive David Wadhwani, is to let creatives focus on the craft so they can “apply their taste and make the calls that only they can”.
One of the assumptions behind today’s AI frameworks is that agents require a “boss” at the center; this orchestrator runs the show, routes requests, and makes sure the whole system doesn’t descend into chaos.
That assumption may be wrong, and the cost of carrying it could be measured in inference dollars and coordination latency. A new Stanford framework called a decentralized language model, or DeLM, is built on the premise that agents can coordinate directly, without routing every update through a central controller.
DeLM’s shared knowledge base serves as a “common communication substrate” so that agents can build upon one another’s verified progress without having to route every interaction through a main agent to “merge, filter, and rebroadcast,” Yuzhen Mao and Azalia Mirhoseini, co-developers of the framework, explain in a research paper.
It’s a system that’s not only possible, but desirable in certain instances. “Agents can build on prior findings, avoid repeated failures, preserve constraints, and recover detailed evidence only when needed.”
In a typical centralized multi-agent system, a main agent breaks tasks into subtasks, assigns them out to multiple sub-agents in parallel, waits for responses, merges and summarizes intermediate progress, then launches a next wave of orders based on collected context.
While this is a natural way to scale large language model (LLM) reasoning, the Stanford researchers argue that it scales poorly. Every useful finding, partial finding, and failure must be reported back to the main agent, which then determines what information to merge and rebroadcast to the agents below it.
“As the number of subtasks grows, this controller becomes a communication and integration bottleneck,” Mao and Mirhoseini write. Further, the main orchestrator may “dilute, omit, or distort” useful information, leading to lost progress.
This bottleneck also occurs in long-context reasoning scenarios. Once it receives reports back from subagents, a main agent will typically group related concepts, data points, and other materials together in an unsupervised learning loop. It may then pre-assign these ‘evidence clusters’ to sub-agents before knowing what surfaced material is actually relevant or whether it’s combined correctly.
When a subagent receives this insufficient context, it will essentially get confused and return to the main agent, kicking off another retrieval or delegation round. “This back-and-forth makes coordination slower, more iterative, and increasingly constrained by a single overloaded main agent,” the researchers write.
DeLM, by contrast, is built around parallel agents, a shared context, and a task queue.
Shared context is essentially a curated store of “gists,” or information summaries that other agents might find useful. These include verified and evidence-based findings alongside partial findings and documented failures; they also point to detailed evidence that agents can pull from based on their specific task.
A task queue is then a set of subsequent pending subtasks that agents can claim independently.
“Agents write compact, verified updates into a shared context that later agents can read directly,” the researchers write. Useful findings, failures, and constraints accumulate as a “shared problem state,” rather than passing through a central controller.
The pipeline looks like this:
Initialization: Inputs are broken into different work units and added to a queue;
Parallel execution: Agents work independently and in tandem, pulling tasks and reading shared context as they progress.
Compression and verification: Results are compressed into reusable “gists” that are checked against supporting evidence. Only gists that are fully verified are shared with the group.
Additional work (if needed): When the queue is emptied, the last agent to return an answer inspects all the shared context to determine whether further work is required.
Final step: The last agent determines that no more steps are required and returns the final answer.
Agents “exchange progress through shared state, asynchronously claim ready tasks, and scale more adaptively as the number of subtasks grows,” the researchers explain.
With DeLM, agents can avoid redundant exploration; reuse and build on each other’s discoveries and failures; and focus on unresolved issues.
The framework can be particularly useful in software engineering test-time scaling, when models are given time to “think” to improve their reasoning and problem-solving capabilities. Different agents can explore their own hypotheses or pursue reasoning paths in parallel, while still sharing intermediate progress. One example is concurrent de-bugging.
DeLM is also suitable for long-context reasoning and multi-document question-answering; agents can simultaneously examine their own evidence clusters (collections of papers, code, or other materials) at the same time, while maintaining a “global compact view” of accumulated evidence.
The researchers contend that it makes agentic tasks more accurate and significantly cheaper. This is backed by its performance on real-world benchmarks: On SWE-bench Verified — which evaluates how well AI models and agents solve real-world software engineering problems — it performed 10.5% better than the strongest baseline and reduced cost per task by roughly 50%.
But it can go beyond coding: On LongBench‑v2 Multi‑Doc QA — which assesses LLMs’ ability to handle long-context, real-world problems — DeLM had the highest accuracy across four model families, including GPT‑5.4, Claude Sonnet, Gemini Flash, and DeepSeek‑V4‑Pro.
DeLM outperforms other models on SWE-Bench for a number of reasons, as Mao detailed on X.
First, agents share failures. In ordinary parallel runs, when one agent follows the wrong path, that failure stays private, and subsequent agents may waste time (and money) pursuing the same dead end. But with DeLM, failed hypotheses are written into shared context.
“Later agents can read them as constraints, avoid repeated exploration, and redirect their search toward more promising fixes,” Mao said.
Additionally, constraints, once verified, are immediately added to agents’ shared context. This means they become a binding shared state. “Later agents inherit them, build around them, and avoid repeating globally invalid simplifications,” Mao said.
Crucially, DeLM keeps shared progress compact enough to reuse. It is unfoldable, meaning agents see short gists by default, but can choose to unfold them into more detailed summaries and raw evidence.
As the researchers note, providing all raw documents and traces gives agents the maximum amount of information, but that can overwhelm their context windows and ultimately increase costs.
“If agents shared full traces, each worker would need to read long command histories, file dumps, failed edits, and intermediate reasoning, turning coordination itself into another long-context bottleneck,” Mao said.
On the other hand, while sharing compact summaries is cheaper, important details and evidence can be lost, resulting in less reliable reasoning.
Unfolding, therefore, provides “coarse-to-fine” opt-in access. This can improve accuracy and cost.
Ultimately, with a framework like DeLM, agents can be more efficient because they are prevented from repeatedly reading the same documents or rerunning the same failed analysis; more effective because useful findings are propagated across parallel threads; and more robust because they only share verified claims.
For enterprise builders, DeLM challenges a core assumption: that every multi-agent workflow needs a central controller. The SWE-bench and LongBench-v2 results suggest the decentralized model isn’t just theoretically cleaner — it’s faster, more accurate, and roughly half the cost.
AI coding agents are rapidly accelerating data engineering by generating transformations, pipelines, orchestration workflows, validation tests, and infrastructure configurations from prompts. However, enterprise data platforms have long operated across…
