Mythos is very powerful, and should feel terrifying. I am proud of our approach to responsibly preview it with cyber defenders, rather than generally releasing it into the wild.

Introducing Claude Managed Agents: everything you need to build and deploy agents at scale.
It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days.
Now in public beta on the Claude Platform.
o3 and o4-mini are super good at coding, so we are releasing a new product, Codex CLI, to make them easier to use.
this is a coding agent that runs on your computer. it is fully open source and available today; we expect it to rapidly improve.
