Parameters

​

Kimi K3 compatibility

• K3 always reasons. Use top-level reasoning_effort: "max"; the K2.x thinking object is accepted only as an enabled compatibility alias.
• Prefer max_completion_tokens. APIAny accepts deprecated max_tokens and converts it only when the selected route targets Kimi K3. If no limit is provided, Kimi’s official default is used. The explicit maximum is 1,048,576 tokens.
• K3 sampling is fixed by the provider. APIAny removes temperature, top_p, frequency_penalty, and presence_penalty only for K3; n must be 1.
• reasoning_content is the reasoning trace and content is the final answer. Streaming returns them as separate deltas. Do not merge the reasoning trace into the final answer.
• Replay the complete assistant message, including reasoning_content and tool_calls, in multi-turn and tool-calling requests.
• The last assistant message may use partial: true. A content-less system message may carry tools to load K3 tools dynamically.
• K3 image/video content blocks must use a Base64 data: URL or an ms:// file ID. Public HTTP media URLs are rejected before the model request is sent.

Notes

• The model is a public APIAny.AI model ID.
• Token usage is normalized into the OpenAI-style usage object when usage data is available.
