Extended-thinking configuration (`thinking` on the Messages request).

Reference version

Signature

class anthropic.ThinkingConfig

Extended-thinking configuration (thinking on the Messages request).

budget_tokens must be smaller than the request's max_tokens, and Anthropic rejects temperature / top_p / top_k alongside enabled thinking — the client sends what it is given and lets the API say so.
