Adaptive thinking () is the recommended thinking mode for Opus 4.6 and Sonnet 4.6. Claude dynamically decides when and how much to think. At the default effort level (), Claude will almost always think. At lower effort levels, it may skip thinking for simpler problems.thinking: {type: "adaptive"}high thinking: {type: "enabled"} and are deprecated on Opus 4.6 and Sonnet 4.6. They remain functional but will be removed in a future model release. Use adaptive thinking and the effort parameter to control thinking depth instead. Adaptive thinking also automatically enables interleaved thinking.budget_tokens
