I've been using Opus 4.6 for a bit -- it is our best model yet. It is more agentic, more intelligent, runs for longer, and is more careful and exhaustive.
For Claude Code users, you can also now more precisely tune how much the model thinks. Run /model and arrow left/right to tune effort (less = faster, more = longer thinking & better results).
Happy coding!

Introducing Claude Opus 4.6. Our smartest model got an upgrade.
Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes.
It’s also our first Opus-class model with 1M token context in beta.
