We’ve doubled usage on weekends, and outside 5a–11am PT on weekdays, through March 27. Works across Claude.ai, Cowork, and Claude Code. Go run your next big idea and thanks for building with us!

Claude@claudeai

A small thank you to everyone using Claude: We’re doubling usage outside our peak hours for the next two weeks.

@mikeyk since you asked for feedback: context management on long claude code sessions still gets messy. but the fact that i push through it every day instead of switching says more about the product than any app store ranking

Claude is #1 in the App Store today — I want to say a huge thank you to all of our new (and existing!) users for the support. We’re working hard for you, please share your thoughts and feedback along the way.

Computer use is the standout. For coding, it’s less prone to overengineering than Opus 4.5 and more consistent over long sessions. And 1M context window in beta on the API. We can't wait to see what you build!

Sonnet 4.6 is here! Same price as Sonnet 4.5 and approaches Opus-level intelligence.

Claude@claudeai

This is Claude Sonnet 4.6: our most capable Sonnet model yet. It’s a full upgrade across coding, computer use, long-context reasoning, agent planning, knowledge work, and design. It also features a 1M token context window in beta.

Congrats to the @dreamer team on their launch today! I got the chance to sit down with @dps and @hbarra for a deep chat on personal agents, building on the Claude Agent SDK, and their startup journey. We could have talked for hours!

Jobs called computers "bicycles for the mind" -- tools we could shape to our will. But they never were. Until now. Every morning an agent preps me for my day -- calendar, news, last 24hrs of Slack -- in a personal podcast. I made it by asking. Same for hundreds of other things. Launching @dreamer in beta today. That 🧠 bicycle, finally. dreamer.com

@dps Congrats on the launch! I've been building on @dreamer and the thoughtfulness throughout the interface + agent builder really comes through.

Reflecting on what engineers love about Claude Code, one thing that jumps out is its customizability: hooks, plugins, LSPs, MCPs, skills, effort, custom agents, status lines, output styles, etc. Every engineer uses their tools differently. We built Claude Code from the ground up to not just have great defaults, but to also be incredibly customizable. This is a reason why developers fall in love with the product, and why Claude Code's growth continues to accelerate. I wanted to share a few ways we're seeing people and teams customize their Claudes.

@akshatk7 You can still use extended thinking, but all the reasoning and answer happens 2.5x faster — you stay in the flow much more (I often feel like I’m the limited factor, not Opus!)

Akshat Khandelwal@akshatk7·8 Şub

Can someone smarter than me (maybe @mikeyk?) tell me why should I use fast Opus? I go for the extended reasoning one all the time assuming that generates a better response. My assumption is faster means less thoughtful response.

I’ve spent all my time after switching to Labs building with fast Opus and it’s a crazy unlock — excited that we’re making it available outside Anthropic too.

Claude@claudeai

Our teams have been building with a 2.5x-faster version of Claude Opus 4.6. We’re now making it available as an early experiment via Claude Code and our API.

Claude Opus 4.6 just launched. It takes development projects from architecture to deployment in hours. At Rakuten, it autonomously closed and assigned issues across a 50-person org. At Harvey, it hit 90.2% — the highest BigLaw Bench score of any Claude model.

Xcode 26.3 launched today with a native integration with the Claude Agent SDK, the same harness that powers Claude Code. Devs get the full power of Claude Code (subagents, background tasks, and plugins) for long-running, autonomous work directly in Xcode 🤖 anthropic.com/news/apple-xco…

There’s never been a better time to be a builder — Opus 4.5 & Claude Code keep surprising me in the quality and completeness of the products they can create. So I’m doing exactly that — putting my product founder hat back on and joining our Labs team to be hands-on at the frontier, building products that channel AI toward solving the world's hardest problems. Excited to pass the baton to Ami Vora as she leads the product team in scaling Claude.

Anthropic@AnthropicAI

We’re expanding Labs—the team behind Claude Code, MCP, and Cowork—and hiring builders who want to tinker at the frontier of Claude’s capabilities. Read more: anthropic.com/news/introduci…

We're donating MCP to the @linuxfoundation and launching the Agentic AI Foundation with @OpenAI, @blocks, @AWS, @Bloomberg, @Cloudflare, @Google, and @Microsoft. MCP went from internal project to industry standard in a year. Now it gets the long-term stewardship it deserves.

Anthropic@AnthropicAI

Anthropic is donating the Model Context Protocol to the Agentic AI Foundation, a directed fund under the Linux Foundation. In one year, MCP has become a foundational protocol for agentic AI. Joining AAIF ensures MCP remains open and community-driven. anthropic.com/news/donating-…

Anthropic is acquiring @bunjavascript! Bun will remain open source and MIT-licensed. We'll keep investing in making it the best runtime, bundler, package manager, and test runner for JS and TS developers, while building even better workflows into Claude Code.
