Today, we are merging Claude Cowork and chat to simplify how you use Claude! We are also integrating Claude Design so that you can ask Claude to make a Slide, Design, or Doc without needing to switch tabs or apps. Many of you shared that you didn't want to choose which Claude product to use for any task. As Claude models have become more capable, we've found that Claude can handle the routing for you. Based on your prompt, Claude will decide whether to give a quick answer or do deeper agentic work, and what kind of output best fits the task. You're in control the whole time: you can still stop, redirect, or exert finer control over Claude's effort or approach. Give it a try and let us know what you think. We're rolling this out slowly over the next few weeks to get it right.

Claude Opus 5.5 is now the default model in Claude Code and the Claude app, including Cowork, for Pro, Max, and Team plans. I’ve been using Opus 5.5 as a daily driver and love its clear communication skills and ability to write in my style. We’re defaulting to effort medium across products, which is comparable to Fable 5.1 on intelligence but faster. Your rate limits will go 25% further on Opus 5.5 compared to Opus 5. Give Opus 5.5 an ambitious task and let us know what you think!

Thanks to your feedback, we’ve unified memory across Chat and Cowork. Now, you can tell Claude to remember something once and it’ll have that context across surfaces! Tell us what you’d like to see next :)

In the new Projects experience, Claude coordinates all of your sessions. I've been using it every day since it lets me operate at a higher level of abstraction. I fire off a batch of tasks and move on. Claude has context on everything I'm working on and can give me an aggregated status update whenever I ask. It also has long-lived memory that evolves as I use it. We're rolling this out over the coming weeks. Let me know what you think!

Sonnet 5.5 is here! In Claude Code, users get ~30% more tasks done compared to Sonnet 5. It's smarter, so it needs fewer tokens for the same work. Here it rakes a yard of leaves using tool calls. 24s faster than Sonnet 5, with 6K fewer tokens. It leaves her extra time to read :)

With Fable 5.1, our team has taken on more ambitious projects that would have previously taken months. What big bets do you want to take? Ask Fable 5.1 in Claude Code, Claude Cowork, Claude Tag to take on the task and let us know what you think!

One of my favorite PM use cases for Claude is asking "who used <feature> the most last week? make me a artifact of the top 10 by usage, then reach out and schedule 15 min to chat." It's the fastest way to get user feedback!

If you’re looking for ways to try Opus 5.5 and Claude Tag in Slack…

We heard your feedback that you want Claude to proactively take more off your plate! Claude Duet is a large step in this direction - it'll notice work that needs to be done, and then do it before you ask. Join the waitlist here: https://claude.com/product/claude-duet
