We’re also launching Claude Sonnet 5.5 and Haiku 5.5 in the coming weeks. These models will come with many of the same improvements to performance, efficiency, and safety.
With that, happy building everyone.

Omid and the team did great work on this one. Most of my Claude Desktop work these days is in these new-style projects and I've really enjoyed how easy it is to kick off a bunch of work while still having a coordinator Claude responding quickly

Super excited to show the world Projects!!
We've been building this for the last few months and it has become my new daily driver. A few tips for getting the most out of it 🧵
I had trouble picturing the whole Iron Tangle level from Dungeon Crawler Carl, so I made an interactive artifact and I think I finally understand it:
Also new today: Claude Docs, Claude Slides and Claude Design are now available in every conversation, powered by a revamped Artifacts platform.
Ask for a design, deck, or document. Get back something you can edit, download, and take anywhere.
Try it out for yourself and let us know what you think.

Claude Cowork and Chat are now one Claude, starting today.
The most common thing we hear: people aren't sure which product to start with. That friction gets in the way of getting the best from what these models can do.
I've been on the unified version for a few weeks and really enjoy it. Claude does the deciding about how to get there, while I get to keep my thinking on the work itself.
Let us know what you think! We'll be getting it dialed in over the coming weeks.

Claude Cowork and chat are merging into one Claude.
Ask a quick question or hand over a report, and Claude takes it from there, even after you close your laptop. If something's unclear, Claude asks—you keep the final say.
Rolling out to Pro and Max over the next few weeks.

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.

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

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.
