Anthropic just released Claude 3.7 Sonnet, the world's first ‘hybrid reasoning’ AI

Anthropic just releasedClaude 3.7 Sonnet, the world's first ‘hybrid reasoning’ AI that can combine instant responses with controllable extended thinking capabilities — alongside a new agentic coding tool called Claude Code.

Claude 3.7 Sonnet enables users to toggle between a standard and "extended thinking" mode, with the latter showing the AI’s reasoning via a scratchpad.
API users can precisely control how long Claude thinks (up to 128K tokens), allowing them to balance speed, cost, and quality based on task complexity.
The AI achieves SOTA performance on real-world coding benchmarks and agentic tool use, surpassing competitors like o1, o3-mini, and DeepSeek R1.
Anthropic also introduced Claude Code, a command-line coding agent that can edit files, read code, and write and run tests, in a limited research preview.

Anthropic has finally brought Claude into the reasoning era — with vastly improved coding benchmarks, precise thinking control, and a new agentic feature that points to a major push on the dev side. With OpenAI also planning a hybrid reasoner, 3.7 may be the start of the next leg up for a new generation of models.
