# Moonshot AI (Kimi)

Moonshot provides the Kimi API with OpenAI-compatible endpoints. Configure the
provider and set the default model to `moonshot/kimi-k2.5`, or use
Kimi Coding with `kimi/kimi-code`.

<Warning>
Moonshot and Kimi Coding are **separate providers**. Keys are not interchangeable, endpoints differ, and model refs differ (`moonshot/...` vs `kimi/...`).
</Warning>

  <Tab title="Kimi Coding">
    **Best for:** code-focused tasks via the Kimi Coding endpoint.

    <Note>
    Kimi Coding uses a different API key and provider prefix (`kimi/...`) than Moonshot (`moonshot/...`). Legacy model ref `kimi/k2p5` remains accepted as a compatibility id.
    </Note>

    <Steps>
      <Step title="Run onboarding">
        ```bash
        openclaw onboard --auth-choice kimi-code-api-key
        ```
      </Step>
      <Step title="Set a default model">
        ```json5
        {
          agents: {
            defaults: {
              model: { primary: "kimi/kimi-code" },

      },
    }

## Kimi web search

OpenClaw also ships **Kimi** as a `web_search` provider, backed by Moonshot web
search.

<Steps>
  <Step title="Run interactive web search setup">
    ```bash
    openclaw configure --section web
    ```

    Choose **Kimi** in the web-search section to store
    `plugins.entries.moonshot.config.webSearch.*`.

  </Step>
  <Step title="Configure the web search region and model">
    Interactive setup prompts for:

    | Setting             | Options                                                              |
    | ------------------- | -------------------------------------------------------------------- |
    | API region          | `https://api.moonshot.ai/v1` (international) or `https://api.moonshot.cn/v1` (China) |
    | Web search model    | Defaults to `kimi-k2.5`                                             |

  </Step>
</Steps>

Config lives under `plugins.entries.moonshot.config.webSearch`:

```json5
{
  plugins: {
    entries: {
      moonshot: {
        config: {
          webSearch: {
            apiKey: "sk-...", // or use KIMI_API_KEY / MOONSHOT_API_KEY
            baseUrl: "https://api.moonshot.ai/v1",
            model: "kimi-k2.5",
          },
        },
      },
    },
  },
  tools: {
    web: {
      search: {
        provider: "kimi",
      },
    },
  },
}
```

## Advanced

<AccordionGroup>
  <Accordion title="Native thinking mode">
    Moonshot Kimi supports binary native thinking:

    - `thinking: { type: "enabled" }`
    - `thinking: { type: "disabled" }`

    Configure it per model via `agents.defaults.models.<provider/model>.params`:

    ```json5
    {
      agents: {
        defaults: {
          models: {
            "moonshot/kimi-k2.5": {
              params: {
                thinking: { type: "disabled" },
              },
            },
          },
        },
      },
    }
    ```

    OpenClaw also maps runtime `/think` levels for Moonshot:

    | `/think` level       | Moonshot behavior          |
    | -------------------- | -------------------------- |
    | `/think off`         | `thinking.type=disabled`   |
    | Any non-off level    | `thinking.type=enabled`    |

    <Warning>
    When Moonshot thinking is enabled, `tool_choice` must be `auto` or `none`. OpenClaw normalizes incompatible `tool_choice` values to `auto` for compatibility.
    </Warning>

  </Accordion>

  <Accordion title="Streaming usage compatibility">
    Native Moonshot endpoints (`https://api.moonshot.ai/v1` and
    `https://api.moonshot.cn/v1`) advertise streaming usage compatibility on the
    shared `openai-completions` transport. OpenClaw keys that off endpoint
    capabilities, so compatible custom provider ids targeting the same native
    Moonshot hosts inherit the same streaming-usage behavior.
  </Accordion>

  <Accordion title="Endpoint and model ref reference">
    | Provider   | Model ref prefix | Endpoint                      | Auth env var        |
    | ---------- | ---------------- | ----------------------------- | ------------------- |
    | Moonshot   | `moonshot/`      | `https://api.moonshot.ai/v1`  | `MOONSHOT_API_KEY`  |
    | Moonshot CN| `moonshot/`      | `https://api.moonshot.cn/v1`  | `MOONSHOT_API_KEY`  |
    | Kimi Coding| `kimi/`          | Kimi Coding endpoint          | `KIMI_API_KEY`      |
    | Web search | N/A              | Same as Moonshot API region   | `KIMI_API_KEY` or `MOONSHOT_API_KEY` |

    - Kimi web search uses `KIMI_API_KEY` or `MOONSHOT_API_KEY`, and defaults to `https://api.moonshot.ai/v1` with model `kimi-k2.5`.
    - Override pricing and context metadata in `models.providers` if needed.
    - If Moonshot publishes different context limits for a model, adjust `contextWindow` accordingly.
