Xiaomi MiMo

Xiaomi MiMo is the API platform for MiMo models. OpenClaw includes a bundled Xiaomi plugin with two text-provider presets:

xiaomi for pay-as-you-go keys (sk-...)
xiaomi-token-plan for Token Plan keys (tp-...) with regional endpoint presets

The same plugin also registers the xiaomi speech (TTS) provider.

Base URLs	Pay-as-you-go: `https://api.xiaomimimo.com/v1`; Token Plan presets: `token-plan-{cn,sgp,ams}...`
Default models	`xiaomi/mimo-v2-flash`, `xiaomi-token-plan/mimo-v2.5-pro`
TTS default	`mimo-v2.5-tts`, voice `mimo_default`; voicedesign model `mimo-v2.5-tts-voicedesign`

Getting started

Get the right key
Create a pay-as-you-go key in the Xiaomi MiMo console, or open your Token Plan subscription page and copy the regional OpenAI-compatible base URL plus the matching tp-... key.

Run onboarding

Pay-as-you-go:

openclaw onboard --auth-choice xiaomi-api-key

Token Plan:

openclaw onboard --auth-choice xiaomi-token-plan-sgp

Or pass the keys directly:

openclaw onboard --auth-choice xiaomi-api-key --xiaomi-api-key "$XIAOMI_API_KEY"
openclaw onboard --auth-choice xiaomi-token-plan-sgp --xiaomi-token-plan-api-key "$XIAOMI_TOKEN_PLAN_API_KEY"

Verify the model is available

openclaw models list --provider xiaomi
openclaw models list --provider xiaomi-token-plan

Text-to-speech

The bundled xiaomi plugin also registers Xiaomi MiMo as a speech provider for messages.tts. It calls Xiaomi’s chat-completions TTS contract with the text as an assistant message and optional style guidance as a user message.

Property	Value
TTS id	`xiaomi` (`mimo` alias)
Auth	`XIAOMI_API_KEY`
API	`POST /v1/chat/completions` with `audio`
Default	`mimo-v2.5-tts`, voice `mimo_default`
Output	MP3 by default; WAV when configured

{
  messages: {
    tts: {
      auto: "always",
      provider: "xiaomi",
      providers: {
        xiaomi: {
          apiKey: "xiaomi_api_key",
          model: "mimo-v2.5-tts",
          speakerVoice: "mimo_default",
          format: "mp3",
          style: "Bright, natural, conversational tone.",
        },
      },
    },
  },
}

Supported built-in voices include mimo_default, default_zh, default_en, Mia, Chloe, Milo, and Dean. Preset-voice models use audio.voice, so OpenClaw sends speakerVoice for mimo-v2.5-tts and mimo-v2-tts.

Xiaomi’s voicedesign model, mimo-v2.5-tts-voicedesign, generates the voice from a natural-language style prompt instead of a preset voice id. Configure style with the desired voice description; OpenClaw sends it as the user message, sends the spoken text as the assistant message, and omits audio.voice for this model.

{
  messages: {
    tts: {
      provider: "xiaomi",
      providers: {
        xiaomi: {
          model: "mimo-v2.5-tts-voicedesign",
          format: "wav",
          style: "Warm, natural female voice with clear pronunciation.",
        },
      },
    },
  },
}

For voice-note targets such as Feishu and Telegram, OpenClaw transcodes Xiaomi output to 48kHz Opus with ffmpeg before delivery.

Config example

{
  env: { XIAOMI_API_KEY: "your-key" },
  agents: { defaults: { model: { primary: "xiaomi/mimo-v2-flash" } } },
  models: {
    mode: "merge",
    providers: {
      xiaomi: {
        baseUrl: "https://api.xiaomimimo.com/v1",
        api: "openai-completions",
        apiKey: "XIAOMI_API_KEY",
        models: [
          {
            id: "mimo-v2-flash",
            name: "Xiaomi MiMo V2 Flash",
            reasoning: false,
            input: ["text"],
            contextWindow: 262144,
            maxTokens: 8192,
          },
          {
            id: "mimo-v2-pro",
            name: "Xiaomi MiMo V2 Pro",
            reasoning: true,
            input: ["text"],
            contextWindow: 1048576,
            maxTokens: 32000,
          },
          {
            id: "mimo-v2-omni",
            name: "Xiaomi MiMo V2 Omni",
            reasoning: true,
            input: ["text", "image"],
            contextWindow: 262144,
            maxTokens: 32000,
          },
        ],
      },
    },
  },
}

Pricing and compat flags come from the bundled plugin manifest, so the config example omits cost and compat to avoid diverging from runtime behavior.

Token Plan:

{
  env: { XIAOMI_TOKEN_PLAN_API_KEY: "tp-your-key" },
  agents: { defaults: { model: { primary: "xiaomi-token-plan/mimo-v2.5-pro" } } },
  models: {
    mode: "merge",
    providers: {
      "xiaomi-token-plan": {
        baseUrl: "https://token-plan-sgp.xiaomimimo.com/v1",
        api: "openai-completions",
        apiKey: "XIAOMI_TOKEN_PLAN_API_KEY",
        models: [
          {
            id: "mimo-v2.5-pro",
            name: "Xiaomi MiMo V2.5 Pro",
            reasoning: true,
            input: ["text"],
            contextWindow: 1048576,
            maxTokens: 131072,
          },
          {
            id: "mimo-v2.5",
            name: "Xiaomi MiMo V2.5",
            reasoning: true,
            input: ["text", "image"],
            contextWindow: 1048576,
            maxTokens: 131072,
          },
        ],
      },
    },
  },
}

Pricing comes from the bundled manifest (Token Plan models include tiered cache-read pricing), so the config example omits cost.

Auto-injection behavior

The xiaomi provider is injected automatically when XIAOMI_API_KEY is set in your environment or an auth profile exists. xiaomi-token-plan needs a regional base URL, so the supported path is the bundled Token Plan onboarding choice or an explicit models.providers.xiaomi-token-plan config block.

Model details

mimo-v2-flash — lightweight and fast, ideal for general-purpose text tasks. No reasoning support.
mimo-v2-pro — supports reasoning with a 1M token context window for long-document workloads.
mimo-v2-omni — reasoning-enabled multimodal model that accepts both text and image inputs.
mimo-v2.5-pro — Token Plan default with Xiaomi’s current V2.5 reasoning stack.
mimo-v2.5 — Token Plan multimodal V2.5 route.

Troubleshooting

If models do not appear, confirm the relevant key env var or auth profile is present and valid.
For Token Plan, confirm the chosen onboarding region matches the subscription page base URL and that the key starts with tp-.
When the Gateway runs as a daemon, ensure the key is available to that process (for example in ~/.openclaw/.env or via env.shellEnv).

Model selection

Choosing providers, model refs, and failover behavior.
