Claude Sonnet 3.7 launched with extended thinking, plus vision for Claude Haiku 3.5

We’ve launched Claude Sonnet 3.7, our most intelligent model yet. Claude Sonnet 3.7 can produce near-instant responses or show its extended thinking step-by-step. One model, two ways to think. Learn more about all Claude models in Models overview.

We’ve added vision support to Claude Haiku 3.5, enabling the model to analyze and understand images.

We’ve released a token-efficient tool use implementation, improving overall performance when using tools with Claude. Learn more in Tool use with Claude.

We’ve changed the default temperature in the Console for new prompts from 0 to 1 for consistency with the default temperature in the API. Existing saved prompts are unchanged.

We’ve released updated versions of our tools that decouple the text edit and bash tools from the computer use system prompt:

bash_20250124: Same functionality as previous version but is independent from computer use. Does not require a beta header.
text_editor_20250124: Same functionality as previous version but is independent from computer use. Does not require a beta header.
computer_20250124: Updated computer use tool with new command options including hold_key, left_mouse_down, left_mouse_up, scroll, triple_click, and wait. This tool requires the computer-use-2025-01-24 anthropic-beta header. Learn more in Tool use with Claude.
