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

<Warning>
MiniMax-M2.x's Anthropic-compatible streaming endpoint emits `reasoning_content` in OpenAI-style delta chunks instead of native Anthropic thinking blocks, which leaks internal reasoning into visible output if thinking is left enabled implicitly. OpenClaw disables M2.x thinking by default unless you explicitly set `thinking` yourself. MiniMax-M3 (and forward-compatible M3.x) is exempt: M3 emits proper Anthropic thinking blocks and requires thinking active to produce visible content, so OpenClaw keeps M3 on the provider's adaptive thinking path. See the Thinking defaults section under Advanced configuration below.
</Warning>

<Note>
API-key setups use the `minimax` provider id. Model refs follow the form `minimax/MiniMax-M3`.
</Note>

Configure via openclaw configure

```bash openclaw configure ``` Choose **Model/auth** from the menu. | Auth choice | Description | | ----------------------- | ----------------------------------- | | `minimax-global-oauth` | International OAuth (Coding Plan) | | `minimax-cn-oauth` | China OAuth (Coding Plan) | | `minimax-global-api` | International API key | | `minimax-cn-api` | China API key | Select your default model when prompted.

Capabilities

Image generation

The MiniMax plugin registers the image-01 model for the image_generate tool on both minimax and minimax-portal, reusing the same MINIMAX_API_KEY or OAuth auth as the text models.

• Text-to-image generation and image-to-image editing (subject reference), both with aspect ratio control
• Up to 9 output images per request, 1 reference image per edit request
• Supported aspect ratios: 1:1, 16:9, 4:3, 3:2, 2:3, 3:4, 9:16, 21:9

{
  agents: {
    defaults: {
      imageGenerationModel: { primary: "minimax/image-01" },
    },
  },
}

Image generation always uses MiniMax's dedicated image endpoint (/v1/image_generation) and ignores models.providers.minimax.baseUrl, since that field configures the chat/Anthropic-compatible base URL instead. Set MINIMAX_API_HOST=https://api.minimaxi.com to route image generation through the CN endpoint; the default global endpoint is https://api.minimax.io.

See [Image Generation](/tools/image-generation) for shared tool parameters, provider selection, and failover behavior.

Text-to-speech

The bundled minimax plugin registers MiniMax T2A v2 as a speech provider for messages.tts.

• Default TTS model: speech-2.8-hd
• Default voice: English_expressive_narrator
• Bundled model ids: speech-2.8-hd, speech-2.8-turbo, speech-2.6-hd, speech-2.6-turbo, speech-02-hd, speech-02-turbo, speech-01-hd, speech-01-turbo, speech-01-240228
• Auth resolution order: messages.tts.providers.minimax.apiKey, then minimax-portal OAuth/token auth profiles, then Token Plan environment keys (MINIMAX_OAUTH_TOKEN, MINIMAX_CODE_PLAN_KEY, MINIMAX_CODING_API_KEY), then MINIMAX_API_KEY
• If no TTS host is configured, OpenClaw reuses the configured minimax-portal OAuth host and strips Anthropic-compatible path suffixes such as /anthropic
• Normal audio attachments stay MP3. Voice-note targets (Feishu, Telegram, and other channels that request a voice-note-compatible attachment) are transcoded from MiniMax MP3 to 48kHz Opus with ffmpeg, because e.g. the Feishu/Lark file API only accepts file_type: "opus" for native audio messages
• MiniMax T2A accepts fractional speed and vol, but pitch is sent as an integer; OpenClaw truncates fractional pitch values before the API request

Setting	Env var	Default	Description
messages.tts.providers.minimax.baseUrl	MINIMAX_API_HOST	https://api.minimax.io	MiniMax T2A API host.
messages.tts.providers.minimax.model	MINIMAX_TTS_MODEL	speech-2.8-hd	TTS model id.
messages.tts.providers.minimax.voiceId	MINIMAX_TTS_VOICE_ID	English_expressive_narrator	Voice id used for speech output.
messages.tts.providers.minimax.speed		1.0	Playback speed, 0.5..2.0.
messages.tts.providers.minimax.vol		1.0	Volume, (0, 10].
messages.tts.providers.minimax.pitch		0	Integer pitch shift, -12..12.

Music generation

The bundled MiniMax plugin registers music generation through the shared music_generate tool for both minimax and minimax-portal.

• Default music model: minimax/music-2.6 (OAuth: minimax-portal/music-2.6)
• Also supports music-2.6-free, music-cover, and music-cover-free
• Prompt controls: lyrics, instrumental
• Output format: mp3
• Session-backed runs detach through the shared task/status flow, including action: "status"

{
  agents: {
    defaults: {
      musicGenerationModel: { primary: "minimax/music-2.6" },
    },
  },
}

See [Music Generation](/tools/music-generation) for shared tool parameters, provider selection, and failover behavior.

Video generation

The bundled MiniMax plugin registers video generation through the shared video_generate tool for both minimax and minimax-portal.

• Default video model: minimax/MiniMax-Hailuo-2.3 (OAuth: minimax-portal/MiniMax-Hailuo-2.3)
• Also supports MiniMax-Hailuo-2.3-Fast, MiniMax-Hailuo-02, I2V-01-Director, I2V-01-live, and I2V-01
• Modes: text-to-video and single-image reference flows
• Supports resolution (768P or 1080P on Hailuo 2.3/02 models); aspectRatio is not supported and is ignored

{
  agents: {
    defaults: {
      videoGenerationModel: { primary: "minimax/MiniMax-Hailuo-2.3" },
    },
  },
}

See [Video Generation](/tools/video-generation) for shared tool parameters, provider selection, and failover behavior.

Image understanding

The MiniMax plugin registers image understanding separately from the text catalog:

Provider ID	Default image model	PDF text extraction
minimax	MiniMax-VL-01	MiniMax-M2.7
minimax-portal	MiniMax-VL-01	MiniMax-M2.7

That is why automatic media routing can use MiniMax image understanding even when the bundled text-provider catalog also includes M3 image-capable chat refs. PDF understanding uses MiniMax-M2.7 for text extraction only; MiniMax does not register a PDF-to-image conversion path.

Web search

The MiniMax plugin also registers web_search through the MiniMax Token Plan search API (/v1/coding_plan/search).

• Provider id: minimax
• Structured results: titles, URLs, snippets, related queries
• Preferred env var: MINIMAX_CODE_PLAN_KEY
• Accepted env aliases: MINIMAX_CODING_API_KEY, MINIMAX_OAUTH_TOKEN
• Compatibility fallback: MINIMAX_API_KEY when it already points at a token-plan credential
• Region reuse: plugins.entries.minimax.config.webSearch.region, then MINIMAX_API_HOST, then MiniMax provider base URLs
• Search stays on provider id minimax; OAuth CN/global setup can steer region indirectly through models.providers.minimax-portal.baseUrl and can provide bearer auth through MINIMAX_OAUTH_TOKEN

Config lives under plugins.entries.minimax.config.webSearch.*.

See [MiniMax Search](/tools/minimax-search) for full web search configuration and usage.

Advanced configuration

| Option | Description | | --- | --- | | `models.providers.minimax.baseUrl` | Prefer `https://api.minimax.io/anthropic` (Anthropic-compatible); `https://api.minimax.io/v1` is optional for OpenAI-compatible payloads | | `models.providers.minimax.api` | Prefer `anthropic-messages`; `openai-completions` is optional for OpenAI-compatible payloads | | `models.providers.minimax.apiKey` | MiniMax API key (`MINIMAX_API_KEY`) | | `models.providers.minimax.models` | Define `id`, `name`, `reasoning`, `contextWindow`, `maxTokens`, `cost` | | `agents.defaults.models` | Alias models you want in the allowlist | | `models.mode` | Keep `merge` if you want to add MiniMax alongside built-ins | On `api: "anthropic-messages"`, OpenClaw injects `thinking: { type: "disabled" }` for MiniMax M2.x models unless an earlier wrapper already set the `thinking` field in the payload. This prevents M2.x's streaming endpoint from emitting `reasoning_content` in OpenAI-style delta chunks, which would leak internal reasoning into visible output.

MiniMax-M3 (and M3.x) is exempt: M3 returns an empty `content` array with `stop_reason: "end_turn"` when thinking is disabled, so OpenClaw removes the implicit disabled default for M3 and, when a thinking level is set, forces `thinking: { type: "adaptive" }` instead.

Available thinking levels per model family:

| Model family   | Levels                                   | Default    |
| -------------- | ----------------------------------------- | ---------- |
| `MiniMax-M3`   | `off`, `adaptive`                        | `adaptive` |
| `MiniMax-M2.x` | `off`, `minimal`, `low`, `medium`, `high` | `off`      |

`/fast on` or `params.fastMode: true` rewrites `MiniMax-M2.7` to `MiniMax-M2.7-highspeed` on the Anthropic-compatible stream path (`api: "anthropic-messages"`, provider `minimax` or `minimax-portal`). **Best for:** keep your strongest latest-generation model as primary, fail over to MiniMax M2.7. Example below uses Opus as a concrete primary; swap to your preferred latest-gen primary model.

```json5
{
  env: { MINIMAX_API_KEY: "sk-..." },
  agents: {
    defaults: {
      models: {
        "anthropic/claude-opus-4-6": { alias: "primary" },
        "minimax/MiniMax-M2.7": { alias: "minimax" },
      },
      model: {
        primary: "anthropic/claude-opus-4-6",
        fallbacks: ["minimax/MiniMax-M2.7"],
      },
    },
  },
}
```

- Coding Plan usage API: `https://api.minimaxi.com/v1/token_plan/remains` or `https://api.minimax.io/v1/token_plan/remains` (requires a coding plan key). - Usage polling derives the host from `models.providers.minimax-portal.baseUrl` or `models.providers.minimax.baseUrl` when configured, so global setups using `https://api.minimax.io/anthropic` poll `api.minimax.io`. Missing or malformed base URLs keep the CN fallback for compatibility. - OpenClaw normalizes MiniMax coding-plan usage to the same `% left` display used by other providers. MiniMax's raw `usage_percent` / `usagePercent` fields are remaining quota, not consumed quota, so OpenClaw inverts them. Count-based fields win when present. - When the API returns `model_remains`, OpenClaw prefers the chat-model entry, derives the window label from `start_time` / `end_time` when needed, and includes the selected model name in the plan label so coding-plan windows are easier to distinguish. - Usage snapshots treat `minimax`, `minimax-cn`, `minimax-portal`, and `minimax-portal-cn` as the same MiniMax quota surface, and prefer stored MiniMax OAuth before falling back to Coding Plan key env vars.

Notes

• Default chat model: MiniMax-M3. Alternate chat models: MiniMax-M2.7, MiniMax-M2.7-highspeed
• Onboarding and direct API-key setup write model definitions for M3 and both M2.7 variants
• Image understanding uses the plugin-owned MiniMax-VL-01 media provider
• Update pricing values in models.json if you need exact cost tracking
• Use openclaw models list to confirm the current provider id, then switch with openclaw models set minimax/MiniMax-M3 or openclaw models set minimax-portal/MiniMax-M3

See [Model providers](/concepts/model-providers) for provider rules.

Troubleshooting

This usually means the **MiniMax provider is not configured** (no matching provider entry and no MiniMax auth profile/env key found). Fix by:

- Running `openclaw configure` and selecting a **MiniMax** auth option, or
- Adding the matching `models.providers.minimax` or `models.providers.minimax-portal` block manually, or
- Setting `MINIMAX_API_KEY`, `MINIMAX_OAUTH_TOKEN`, or a MiniMax auth profile so the matching provider can be injected.

Make sure the model id is **case-sensitive**:

- API-key path: `minimax/MiniMax-M3`, `minimax/MiniMax-M2.7`, or `minimax/MiniMax-M2.7-highspeed`
- OAuth path: `minimax-portal/MiniMax-M3`, `minimax-portal/MiniMax-M2.7`, or `minimax-portal/MiniMax-M2.7-highspeed`

Then recheck with:

```bash
openclaw models list
```
