# 模型参数参考

export const DocTable = ({columns = [], rows = []}) => {
  return <div className="doc-table-wrap">
      <table className="doc-table">

不同模型系列对 Chat Completions API 参数有不同的默认值和约束。完整的模型列表请参阅[模型列表](/models)。

<Note>
  当 `temperature` 接近 0 时，`n` 只能为 1，否则将返回 `invalid_request_error`。

## Kimi K2.6 — thinking 参数

Kimi K2.6 支持通过 `thinking` 参数控制是否启用深度思考。接受 `{"type": "enabled"}` 或 `{"type": "disabled"}`。

由于 OpenAI SDK 没有原生的 `thinking` 参数，需要使用 `extra_body` 传递：

<CodeGroup>
  ```python Python theme={null}
  completion = client.chat.completions.create(
      model="kimi-k2.6",
      messages=[
          {"role": "user", "content": "你好"}
      ],
      extra_body={
          "thinking": {"type": "disabled"}
      },
      max_tokens=1024*32,
  )
  ```

  ```bash cURL theme={null}
  curl https://api.moonshot.cn/v1/chat/completions \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer $MOONSHOT_API_KEY" \
    -d '{
      "model": "kimi-k2.6",
      "messages": [
        {"role": "user", "content": "你好"}
      ],
      "thinking": {"type": "disabled"}
    }'
  ```
