New in Xcode 26 Beta 7: Users can now log into their Claude account from Xcode. Generate code and documentation, automatically fix errors, and create inline playgrounds using coding intelligence features in Xcode, powered by Claude Sonnet 4.
@AnthropicAI's Opus 4.1 is the new #1 model on our Finance Agent Benchmark and the first model to break 50%. It's proven itself to be the new top-of-the-line model for agentic enterprise work! (1/4)
Claude Sonnet 4 now supports 1 million tokens of context on the Anthropic API—a 5x increase. Process over 75,000 lines of code or hundreds of documents in a single request.
Particularly excited for this launch — Claude Code can now review your code for security vulnerabilities. We're using this internally at Anthropic and it's already caught issues before we shipped them.

Today we're releasing Claude Opus 4.1, an upgrade to Claude Opus 4 on agentic tasks, real-world coding, and reasoning.
Healthcare data is way too siloed, and it’s time to fix it — happy for @AnthropicAI to take part in this initiative from @CMSGov and the @WhiteHouse for secure, privacy-preserving data sharing between health record systems and products like Claude

Claude Code now lets you create teams of custom agents. We'd love to hear what you build.

Six months ago I watched Claude burn $5 to butter toast, code I could've typed in 30 seconds. Today it opens 100% of my PRs and I haven't typed a function in weeks. every.to/source-code/ho…
Another fun launch this week — we've made it way, way easier to add local MCP servers through a one-click install process and a new open-source file format we call DXT

Over 500M Artifacts have been created since we launched! And today, your Artifacts can now embed Claude's intelligence in them; we call it "Claude in Claude" internally and it's been a blast to see what people create with it.

We're hiring for the Claude Code team! In particular, we're looking for a Systems Engineer (job-boards.greenhouse.io/anthropic/jobs…) and an Eng Manager (job-boards.greenhouse.io/anthropic/jobs…). The Claude Code team is having a blast, come join us :)
Our engineering & research team put together a deep dive on the multi-agent system that powers our Research capability in Claude[dot]ai; lots of fun details architectural diagrams, and prompting learnings here: anthropic.com/engineering/bu…
Had a great chat today with university students in Paris (at the beautiful Sorbonne). Lots of amazing young builders here, the energy was great!
One of our top feature requests! I've used this to work with very large knowledge bases in my Projects and it's very handy

Honored that Reed Hastings is joining @AnthropicAI's board! Reed's track record at Netflix is legendary and I’ve been even more inspired by his investments in education and his work accelerating digital economic development in Africa. anthropic.com/news/reed-hast…
Some fun user stats from day one of Claude 4: * New Max subscribers tripled * New Pro subscribers tripled * Claude Code usage increased 40% * Claude 4 already accounts for over 60% of our first party API
