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.

Fast mode is more expensive to run. It’s for urgent, high-stakes projects, combining impressive speed with Opus-level intelligence.

Fast mode is available now for Claude Code users with extra usage enabled (use /fast).

It’s also available in research preview on @cursor_ai, @emergentlabs, @FactoryAI, @figma, @github Copilot, @Lovable, @v0, and @windsurf.

@cursor_ai @emergentlabs @FactoryAI @figma @github @Lovable @v0 @windsurf We plan to expand API access to more customers. You can join the waitlist here: claude.com/fast-mode

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.

Opus 4.6 is state-of-the-art on several evaluations including agentic coding, multi-discipline reasoning, knowledge work, and agentic search.

We're also shipping new features across Claude in Excel, Claude in PowerPoint, Claude Code, and our API to let Opus 4.6 do even more.

Claude in Excel now handles long-running and harder tasks with improved performance.

It can plan before acting, support richer functionalities like conditional formatting and data validation, and handle multi-step changes in one pass.

Introducing Cowork: Claude Code for the rest of your work.

Cowork lets you complete non-technical tasks much like how developers use Claude Code.

In Cowork, you give Claude access to a folder on your computer. Claude can then read, edit, or create files in that folder.

Try it to create a spreadsheet from a pile of screenshots, or produce a first draft from scattered notes.

Once you've set a task, Claude makes a plan and steadily completes it, looping you in along the way.

Claude will ask before taking any significant actions so you can course-correct as needed.

Claude in Chrome is now available to all paid plans.

We’ve also shipped an integration with Claude Code.

Using the extension, Claude Code can test code directly in the browser to validate its work. Claude can also see client-side errors via console logs.

Try it out by running /chrome in the latest version of Claude Code.
