New on our Frontier Red Team blog: using Claude to formally verify software at large scale.
Formal verification can prove that code is free of certain bugs, but historically it has only been feasible for small codebases (or required a lot of expert time).
With AI models, however, this is beginning to change. In collaboration with @theoremlabs, we used Claude to prove security properties in over one hundred real-world open-source libraries over the span of a few weeks.

OpenAI, Anthropic and other leading AI labs face a growing challenge: Better models aren't necessarily attracting more usage. A 10-point intelligence advantage now earns just 20% more developer traffic, down from nearly 69% in late 2025.

Lots of ChatGPT / Codex users seem to be reporting their usage limits draining way faster than normal since Oct 16. Some even saw their quota wiped in seconds, and the complaints kept coming after yesterday's reset.
Despite the improvements Tibo announced, I still miss being able to actually track those changes rolling out and making a real difference day to day, in real time.
We placed the fruit fly brain inside Odyssey-3, a frontier world model.
The lil’ guy is now flying around totally imagined, simulated worlds all by itself 🫶
We keep improving performance across Claude, and you may have noticed it starts responding sooner!
Claude Code now gzips the conversation it sends on every turn, so it reaches the model faster. Cloud sessions also start up as soon as you start typing.
Claude writes about 90% of Claude Code's code.
From June to September, merged PRs more than doubled while the share reverted fell by more than 40%.
We wrote about how we changed code review to get there, and how to adopt it:
