Claude Code now lets you create teams of custom agents. We'd love to hear what you build.
Claude Code is getting a brand new feature: custom subagents. Type `/agents` to get started.
Today I'm excited to share that I'm joining @Figma's board of directors. Having known Dylan (@zoink) for years and watched him build the platform that's become essential for design teams, I'm looking forward to partnering with him and the Figma team on what's next!
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
We've simplified local MCP usage by creating something new we call Desktop Extensions (.dxt files). These package your local server, handle dependencies, and provide secure configuration so you can one-click share and install local servers on Claude Desktop and other apps.
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.
Introducing two new ways to create with Claude: A dedicated space for building, hosting, and sharing artifacts, and the ability to embed AI capabilities directly into your creations.
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
Projects on Claude now support 10x more content. When you add files beyond the existing threshold, Claude switches to a new retrieval mode to expand the functional context.
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
Dream collaboration!
THE WAY OF CODE, a project by @rickrubin in collaboration with Anthropic:
Today, we're announcing four new capabilities on the Anthropic API to help developers build more powerful AI agents. A code execution tool, MCP connector, Files API, and extended prompt caching:
Claude 4 is here: Opus 4 and Sonnet 4 are now live! These are the best coding models in the world. Opus 4 can handle complex tasks for hours on end – one team ran it for 7 straight hours refactoring code. No more painful either/or decisions for founders. Looking forward to…
Just shipped web search to our API! We already use this in Claude Code to dynamically fetch documentation or other info, now you can build it into your apps too.
Web search is now available on our API. Developers can augment Claude's comprehensive knowledge with up-to-date data.
Have been using Research a ton internally — both for searching and synthesizing internal data, and gathering information from the web. I’ve especially liked using it for insights on my calendar and how I’m spending my time.
Today we’re launching Research, alongside a new Google Workspace integration. Claude now brings together information from your work and the web.
We're hosting our first developer conference in May! More details here: anthropic.com/news/Introduci…
Fun working with our design + front-end team on these — really happy with how this refresh is turning out
We've done some spring cleaning. The Claude interface is now more refined, thanks to your feedback.
