We launched Claude Fable 5.1 this morning! Fable models are built for complex, multi-step work that runs on its own, and Fable 5.1 sets a new standard across coding, knowledge work, and long-running problem-solving tasks.

We’re introducing Claude Fable 5.1 and Claude Mythos 5.1. They're the world’s most advanced models for coding and knowledge work.

Opus 5 quickly became my daily driver both at work and on the weekends. It can work for hours on complex tasks, and I've found it consistently gets to the bottom of tricky tasks. I also had some fun building some games with it 🧵

New today as Claude Cowork starts rolling out to web and mobile: Chat and Cowork now share one home tab on web and desktop — one sidebar, one search, and one place for your Projects & Artifacts. Keep an eye out for even better Chat + Cowork integration soon, too.

One of my favorite things we've shipped recently — used it today to visualize a tricky set of experiment gates & logic, and communicate that to the team.

Artifacts in Claude Code are now also available on Pro and Max plans. Ask for an artifact, Claude writes the code, publishes it live to claude.a‍i, and updates it in real time while it keeps working. Pages are private to your account and fully self-contained.

Our Labs team worked on this along with the Claude Code team — as Claude's work gets deeper and more independent, I've found really valuable to have it explain its thinking and outputs using Artifacts; try asking it to diagram its work next time you're working with it.

New in Claude Code: Artifacts. Interactive pages built from your session, like a PR walkthrough or a living project dashboard, shared with your team at a private link. Available in beta on Team and Enterprise plans.
