Introducing Claude 3.7 Sonnet: our most intelligent model to date. It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking. One model, two ways to think. We’re also releasing an agentic coding tool: Claude Code.

This approach has made Sonnet the model of choice for developers worldwide. In addition to our new model, we're launching Claude Code, our first coding tool, in a limited research preview. With Claude Code, you can delegate substantial tasks to Claude—right from your terminal.

We're opening limited access to a research preview of a new agentic coding tool we're building: Claude Code. You'll get Claude-powered code assistance, file operations, and task execution directly from your terminal. Here’s what it can do:

Today, we introduced Claude 3.7 Sonnet and Claude Code! Claude 3.7 Sonnet is our smartest model yet and the first hybrid reasoning model on the market. Claude Code is a command line tool for agentic coding, so developers can hand off complex engineering jobs to Claude. Can't

What happens when you let Claude work on the same problem not just for a few seconds but for a few hours? Claude speeds up my work everyday, but I still need to be there, pairing with it. As an experiment, I set up a sandbox where Claude could keep working indefinitely... 🧵

Introducing Sonnet 3.7 and Claude Code, Anthropic’s new agentic coding assistant. The team and I have been hacking on Code for a while — can’t wait to hear what everyone thinks. anthropic.com/news/claude-3-…

The Claude Code team just mailed out hand written notes and stickers to users who cracked our Sticker Easter Egg!! Seeing 750+ of you discover our little secret made our dev hearts skip a beat. Stay tuned for more 🔍✨

Thanks to Claude Code users for contributing incredible feedback! We just shipped more features based on what we’re hearing from you all. See Cat’s thread for details on auto-accept mode, auto-compact for context, and filepath autocomplete.

Thanks swyx + AI Engineer World's Fair for hosting me for a talk on the big stage last week! I did a speed run through the evolution of coding UX since the 1950's, and where I think we're headed. Video: youtube.com/watch?v=U-fMsb… Slides: docs.google.com/presentation/d…
