  Context window is 262,144 tokens per the pricing page. The response_format guide says K2.6 supports structured output but can be unstable with complex schemas. tool_choice required is not supported. The quickstart gives only a 32K default for max_tokens, and the Chat API reference states an upper limit for Kimi K3 alone, so no maximum output is published.
