Anthropic: Claude 3.7 Sonnet (thinking)
The extended thinking variant of Claude 3.7 Sonnet delivers meaningfully stronger reasoning and math performance, with vision, tool use, and a 200K context window — making it a solid choice for complex analytical tasks. However, it has been superseded by newer Claude Sonnet releases, so it sits just above its non-thinking sibling in the current landscape.

Claude 3.7 Sonnet is an advanced large language model with improved reasoning, coding, and problem-solving capabilities. It introduces a hybrid reasoning approach, allowing users to choose between rapid responses and extended, step-by-step processing for complex tasks. The model demonstrates notable improvements in coding, particularly in front-end development and full-stack updates, and excels in agentic workflows, where it can autonomously navigate multi-step processes. Claude 3.7 Sonnet maintains performance parity with its predecessor in standard mode while offering an extended reasoning mode for enhanced accuracy in math, coding, and instruction-following tasks.
