Providers

Moonshot AI

Moonshot provides the Kimi API with OpenAI-compatible endpoints. Configure the provider and set the default model to moonshot/kimi-k2.6, or use Kimi Coding with kimi/kimi-code.

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-k2.5`	Kimi K2.5	No	text, image	262,144	262,144
`moonshot/kimi-k2-thinking`	Kimi K2 Thinking	Yes	text	262,144	262,144
`moonshot/kimi-k2-thinking-turbo`	Kimi K2 Thinking Turbo	Yes	text	262,144	262,144
`moonshot/kimi-k2-turbo`	Kimi K2 Turbo	No	text	256,000	16,384

Bundled cost estimates for current Moonshot-hosted K2 models use Moonshot's published pay-as-you-go rates: Kimi K2.6 is $0.16/MTok cache hit, $0.95/MTok input, and $4.00/MTok output; Kimi K2.5 is $0.10/MTok cache hit, $0.60/MTok input, and $3.00/MTok output. Other legacy catalog entries keep zero-cost placeholders unless you override them in config.

Getting started

Choose your provider and follow the setup steps.

Moonshot API

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

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

Run onboarding

openclaw onboard --auth-choice moonshot-api-key

Or for the China endpoint:

openclaw onboard --auth-choice moonshot-api-key-cn

Set a default model

{
  agents: {
    defaults: {
      model: { primary: "moonshot/kimi-k2.6" },
    },
  },
}

Verify models are available

openclaw models list --provider moonshot

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:

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 off \
  --json

The JSON response should report provider: "moonshot" and model: "kimi-k2.6". The assistant transcript entry stores normalized token usage plus estimated cost under usage.cost when Moonshot returns usage metadata.

}

Kimi Coding

Best for: code-focused tasks via the Kimi Coding endpoint.

Run onboarding

openclaw onboard --auth-choice kimi-code-api-key

Set a default model

{
  agents: {
    defaults: {
      model: { primary: "kimi/kimi-code" },
    },
  },
}

Verify the model is available

openclaw models list --provider kimi

Config example

{
  env: { KIMI_API_KEY: "sk-..." },
  agents: {
    defaults: {
      model: { primary: "kimi/kimi-code" },
      models: {
        "kimi/kimi-code": { alias: "Kimi" },
      },
    },
  },
}

Kimi web search

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

Run interactive web search setup

openclaw configure --section web

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

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-k2.6`

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

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:

{
  agents: {
    defaults: {
      models: {
        "moonshot/kimi-k2.6": {
          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`

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.

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

Tool call id sanitization

Moonshot Kimi serves tool_call ids shaped like functions.<name>:<index>. OpenClaw preserves them unchanged so multi-turn tool calls keep working.

To force strict sanitization on a custom OpenAI-compatible provider, set sanitizeToolCallIds: true:

{
  models: {
    providers: {
      "my-kimi-proxy": {
        api: "openai-completions",
        sanitizeToolCallIds: true,
      },
    },
  },
}

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.

With the bundled 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.

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