- Fable 5 is back.
- Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.
- Introducing Claude Code Security, now in limited research preview. It scans codebases for vulnerabilities and suggests targeted software patches for human review, allowing teams to find and fix issues that traditional tools often miss. Learn more: https://t.co/n4SZ9EIklG https://t.co/zw9NjpqFz9
- Claude can now build interactive charts and diagrams, directly in the chat. Available today in beta on all plans, including free. Try it out: http://claude.ai
- 1 million context window: Now generally available for Claude Opus 4.6 and Claude Sonnet 4.6.
- 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.
