Anthropic agreed to pay $1.5bn to the authors whose books it pirated. The money is now being counted out. Some of those authors are discovering that a share of it goes to their own publishers. The New York Times reported on Friday that authors and publ…

A mathematician holds a five-year grant to formalise Fermat’s Last Theorem. It has been done for him in eleven days, and he says the result tells us nothing about mathematics. Anthropic published the proof on Friday. Dozens of Claude agents wrote 13 mi…

OpenAI declared the AGI era on the strength of a 99.9% score. Run the same model through the benchmark’s own software, and it scores 62.7%. The gap is not a rounding error or a rival’s complaint. It comes from the organisation that built the test. ARC …

CrowdStrike said on Wednesday that it will run OpenAI’s GPT-5.6 Cyber inside a purpose-built cyber harness. That word is doing a great deal of work. It is also the word that made this week’s other cybersecurity story alarming. The expanded OpenAI partn…

Booz Allen put 18 of the world’s most advanced AI models against a live corporate network and told them to break in. One of them finished the job. The consulting firm says the ranking it produced is the wrong thing to take away from it. The Cyber Weapo…
