Claude Sonnet is the tier in Anthropic's Claude lineup that strikes the best balance between speed and capability. It sits between the lighter Haiku and the more powerful Claude Opus and has become the most-used variant for production assistants and coding workflows. Tools like Claude Code and Cursor use it as a core engine, and it supports modern features such as Tool Use and Extended Thinking. Trained with Constitutional AI, its Refusal calibration is one of the recurring competitive talking points around the model.
