    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.

    Excited to ship Claude Haiku 4.5 today! What was state-of-the-art 5 months ago (Sonnet 4) is now available at 1/3 the cost and 2x the speed. Even beats Sonnet 4 at computer use. Available today wherever you get your Claude :)
