Configure Moonshot Kimi models vs Kimi Coding (separate providers + keys)	You want Moonshot Kimi K3/K2 (Moonshot Open Platform) vs Kimi Coding setup You need to understand separate endpoints, keys, and model refs You want copy/paste config for either provider	Moonshot AI

Moonshot provides the Kimi API with OpenAI-compatible endpoints. Select moonshot/kimi-k3 for Kimi K3, keep the onboarding default moonshot/kimi-k2.6, or use kimi/kimi-for-coding for Kimi Coding.

Moonshot and Kimi Coding are **separate providers**, each shipped as a separate external plugin. Keys are not interchangeable, endpoints differ, and model refs differ (`moonshot/...` vs `kimi/...`).

Built-in model catalog

Model ref	Name	Reasoning	Input	Context	Max output
moonshot/kimi-k2.6	Kimi K2.6	No	text, image	262,144	262,144
moonshot/kimi-k3	Kimi K3	Always max	text, image	1,048,576	1,048,576
moonshot/kimi-k2.7-code	Kimi K2.7 Code	Always on	text, image	262,144	262,144
moonshot/kimi-k2.7-code-highspeed	Kimi K2.7 Code HighSpeed	Always on	text, image	262,144	262,144
moonshot/kimi-k2.5	Kimi K2.5	No	text, image	262,144	262,144

Catalog cost estimates use Moonshot's published pay-as-you-go rates. Check the live vendor pages for Kimi K3, Kimi K2.7 Code, Kimi K2.6, and Kimi K2.5 before making cost decisions.

Kimi K3 always reasons at reasoning_effort: "max". OpenClaw exposes only /think max, omits the K2-only thinking field, and removes sampling overrides (temperature, top_p, n, presence_penalty, and frequency_penalty) that K3 fixes to provider defaults. Kimi K2.7 Code also always uses native thinking but requires both thinking and reasoning_effort to be omitted; the HighSpeed variant uses the same contract. Kimi K2.6 remains the onboarding default. See Moonshot's Kimi K3 quickstart.

Getting started

Both Moonshot and Kimi Coding are external plugins - install one before onboarding.

**Best for:** Kimi K3 and K2 models via the Moonshot Open Platform.

<Steps>
  <Step title="Install the plugin">
    ```bash
    openclaw plugins install @openclaw/moonshot-provider
    openclaw gateway restart
    ```
  </Step>
  <Step title="Choose your endpoint region">
    | Auth choice            | Endpoint                       | Region        |
    | ---------------------- | ------------------------------ | ------------- |
    | `moonshot-api-key`     | `https://api.moonshot.ai/v1`   | International |
    | `moonshot-api-key-cn`  | `https://api.moonshot.cn/v1`   | China         |
  </Step>
  <Step title="Run onboarding">
    ```bash
    openclaw onboard --auth-choice moonshot-api-key
    ```

    Or for the China endpoint:

    ```bash
    openclaw onboard --auth-choice moonshot-api-key-cn
    ```
  </Step>
  <Step title="Set Kimi K3 as the default model">
    Onboarding keeps Kimi K2.6 as the initial default. Switch explicitly
    when you want Kimi K3:

    ```bash
    openclaw models set moonshot/kimi-k3
    ```
  </Step>
  <Step title="Verify models are available">
    ```bash
    openclaw models list --provider moonshot
    ```
  </Step>
  <Step title="Run a live smoke test">
    Use an isolated state dir when you want to verify model access and cost
    tracking without touching your normal sessions:

    ```bash
    OPENCLAW_CONFIG_PATH=/tmp/openclaw-kimi/openclaw.json \
    OPENCLAW_STATE_DIR=/tmp/openclaw-kimi \
    openclaw agent --local \
      --session-id live-kimi-cost \
      --message 'Reply exactly: KIMI_LIVE_OK' \
      --thinking max \
      --json
    ```

    The JSON response should report `provider: "moonshot"` and
    `model: "kimi-k3"`. The assistant transcript entry stores normalized
    token usage plus estimated cost under `usage.cost` when Moonshot returns
    usage metadata.
  </Step>

        ],
      },
    },
  },
}
```

**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/...`). Current refs are `kimi/k3` for a 256K context, `kimi/k3[1m]` for the 1M tier, `kimi/kimi-for-coding`, and `kimi/kimi-for-coding-highspeed`. Legacy refs `kimi/kimi-code` and `kimi/k2p5` remain accepted and normalize to `kimi/kimi-for-coding`.
</Note>

The coding service accepts both OpenAI-compatible
`https://api.kimi.com/coding/v1` and Anthropic-compatible
`https://api.kimi.com/coding/` clients. This plugin uses Anthropic Messages.

<Steps>
  <Step title="Install the plugin">
    ```bash
    openclaw plugins install @openclaw/kimi-provider
    openclaw gateway restart
    ```
  </Step>
  <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-for-coding" },
        },
      },
    }
    ```
  </Step>
  <Step title="Verify the model is available">
    ```bash
    openclaw models list --provider kimi
    ```
  </Step>
</Steps>

Kimi Code K3 defaults to deep thinking at `max`. `/think off` sends
`thinking.type: "disabled"`; `/think max` sends K3's adaptive-thinking
request with max effort. Stale lower thinking levels resolve to the
supported `max` level. The 1M model requires an Allegretto or higher Kimi
membership; use `kimi/k3` on Moderato.

See the official [Kimi Code model table](https://www.kimi.com/code/docs/en/kimi-code/models.html) for current plan availability.

### Config example

```json5
{
  env: { KIMI_API_KEY: "sk-..." },
  agents: {
    defaults: {
      model: { primary: "kimi/kimi-for-coding" },
      models: {
        "kimi/kimi-for-coding": { alias: "Kimi" },
      },
    },
  },
}
```

Kimi web search

The Moonshot plugin also registers Kimi as a web_search provider, backed by Moonshot web search.

```bash openclaw configure --section web ```

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

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-k2.6`                                             |

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

{
  plugins: {
    entries: {
      moonshot: {
        config: {
          webSearch: {
            apiKey: "sk-...", // or use KIMI_API_KEY / MOONSHOT_API_KEY
            baseUrl: "https://api.moonshot.ai/v1",
            model: "kimi-k2.6",
          },
        },
      },
    },
  },
  tools: {
    web: {
      search: {
        provider: "kimi",
      },
    },
  },
}

Advanced configuration

Moonshot API Kimi K3 always reasons at maximum effort. OpenClaw exposes only `/think max`, sends `reasoning_effort: "max"`, and ignores stale lower or `off` settings.

Kimi Code K3 exposes `/think off|max`. Its Anthropic-compatible endpoint
receives `thinking.type: "disabled"` for off, or adaptive thinking with
`output_config.effort: "max"` for max. This applies to both `kimi/k3` and
`kimi/k3[1m]`.
Moonshot API K3 supports `auto`, `none`, `required`, and pinned tool choices,
so OpenClaw preserves the requested `tool_choice`. For multi-turn tool use,
OpenClaw preserves the assistant reasoning content required by Moonshot's
replay contract.

Kimi K2.7 Code always uses native thinking. Moonshot requires clients to
omit the `thinking` field for this model, so OpenClaw exposes only `on` and
ignores stale `off` settings. K2.7 also fixes `temperature`, `top_p`, `n`,
`presence_penalty`, and `frequency_penalty`; OpenClaw omits configured
overrides for those fields.

Other Moonshot Kimi models support 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-k2.6": {
          params: {
            thinking: { type: "disabled" },
          },
        },
      },
    },
  },
}
```

OpenClaw maps runtime `/think` levels for those models:

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

<Warning>
When Moonshot K2 thinking is enabled, `tool_choice` must be `auto` or `none`. A pinned tool choice (`type: "tool"` or `type: "function"`) forces thinking back to `disabled` instead, so the requested tool still runs; `tool_choice: "required"` is normalized to `auto` instead. Kimi K2.7 Code cannot disable thinking, so its incompatible `tool_choice` is normalized to `auto`. Kimi K3 uses its separate reasoning-effort contract and preserves supported tool choices.
</Warning>

Kimi K2.6 also accepts an optional `thinking.keep` field that controls
multi-turn retention of `reasoning_content`. Set it to `"all"` to keep full
reasoning across turns; omit it (or leave it `null`) to use the server
default strategy. OpenClaw only forwards `thinking.keep` for
`moonshot/kimi-k2.6` and strips it from other models. Kimi K2.7 Code
preserves full reasoning history by default while OpenClaw omits the entire
`thinking` field.

```json5
{
  agents: {
    defaults: {
      models: {
        "moonshot/kimi-k2.6": {
          params: {
            thinking: { type: "enabled", keep: "all" },
          },
        },
      },
    },
  },
}
```

Moonshot Kimi serves native tool_call ids shaped like `functions.:`. OpenClaw preserves the first occurrence of each native Kimi id and rewrites later duplicates to deterministic OpenAI-style `call_*` ids. Matching tool results are remapped with the same id so replay remains unique without stripping Kimi's first native id. This behavior is wired into the bundled Moonshot provider and is not a user-configurable setting. Native Moonshot endpoints (`https://api.moonshot.ai/v1` and `https://api.moonshot.cn/v1`) advertise streaming usage compatibility. OpenClaw keys this off the endpoint host, not the provider id, so a custom provider id pointed at the same native Moonshot host inherits the same streaming-usage behavior.

With the catalog K2.6 pricing, streamed usage that includes input, output,
and cache-read tokens is also converted into local estimated USD cost for
`/status`, `/usage full`, `/usage cost`, and transcript-backed session
accounting.

| 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-k2.6`.
- Override pricing and context metadata in `models.providers` if needed.
- If Moonshot publishes different context limits for a model, adjust `contextWindow` accordingly.
