MAX changelog updates:

  • Kimi K2.5 tool calling now supports interleaved thinking: a single
    assistant turn may interleave multiple <think>...</think> reasoning
    blocks with multiple tool-call sections and end with <|im_end|>. The
    constrained-decoding grammar (used for tool_choice and JSON
    response_format) admits up to eight tool-call sections with an optional
    reasoning block before each, and lets the model stop before the cap. This
    fixes a tool_choice=auto failure where a second tool-call section
    disabled grammar enforcement for the rest of the request.
