Anthropic launches Claude Sonnet 5.5, nearly as smart as its top model
Anthropic's mid-sized model now scores just behind its largest model on independent tests, at the same price as before. It gets there by reasoning at greater length than any model measured so far. That makes each task about 50 percent more expensive.

OpenAI's agents solve a Millennium Prize problem, and two mathematicians ask where the route came from
On 8 September OpenAI said that about 10,000 agents, running on an internal model, had found a proof in 88 hours that solutions to the three-dimensional Navier-Stokes equations can break down. A computer checked the proof in Lean. Half a day earlier, Tristan Buckmaster of New York University had published related results with Levent Alpöge, together with a statement on how OpenAI moved onto the same problem after hearing rumours about their work. The dispute is about credit and about what happens to user data. Nobody has shown that anything was stolen.

Genome language models design working viruses
The journal Science published research by Samuel King, Brian Hie and colleagues at Stanford and the Arc Institute, in which genome language models designed complete new bacteriophages. These are language models trained on genetic code instead of text. Of about 300 designs the team made in the lab, 16 worked. Combinations of them overcame E. coli strains that resist the natural phage ΦX174.
