The first hybrid reasoning model from Anthropic, combining standard responses with extended thinking mode. Sonnet 3.7 introduced transparent step-by-step reasoning and excelled at coding and front-end development. With 200K context, 64K output, and thinking capabilities, it bridged the gap between Claude 3.5 and Claude 4. This model has been retired and is no longer available for use.
