MiniMax

OpenClaw's MiniMax provider defaults to MiniMax M2.7.

MiniMax also provides:

• Bundled speech synthesis via T2A v2
• Bundled image understanding via MiniMax-VL-01

### Config example

```json5
{
  env: { MINIMAX_API_KEY: "sk-..." },
  agents: { defaults: { model: { primary: "minimax/MiniMax-M2.7" } } },
  models: {
    mode: "merge",
    providers: {
      minimax: {
        baseUrl: "https://api.minimax.io/anthropic",
        apiKey: "${MINIMAX_API_KEY}",
        api: "anthropic-messages",
        models: [
          {
            id: "MiniMax-M2.7",
            name: "MiniMax M2.7",
            reasoning: true,
            input: ["text"],
            cost: { input: 0.3, output: 1.2, cacheRead: 0.06, cacheWrite: 0.375 },
            contextWindow: 204800,
            maxTokens: 131072,
          },
          {
            id: "MiniMax-M2.7-highspeed",
            name: "MiniMax M2.7 Highspeed",
            reasoning: true,
            input: ["text"],
            cost: { input: 0.6, output: 2.4, cacheRead: 0.06, cacheWrite: 0.375 },
            contextWindow: 204800,
            maxTokens: 131072,
          },
        ],
      },
    },
  },
}
```

<Warning>
On the Anthropic-compatible streaming path, OpenClaw disables MiniMax thinking by default unless you explicitly set `thinking` yourself. MiniMax's streaming endpoint emits `reasoning_content` in OpenAI-style delta chunks instead of native Anthropic thinking blocks, which can leak internal reasoning into visible output if left enabled implicitly.
</Warning>

<Note>
API-key setups use the `minimax` provider id. Model refs follow the form `minimax/MiniMax-M2.7`.
</Note>

Configure via openclaw configure

Use the interactive config wizard to set MiniMax without editing JSON:

| 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 |

Capabilities

Image generation

The MiniMax plugin registers the image-01 model for the image_generate tool. It supports:

• Text-to-image generation with aspect ratio control
• Image-to-image editing (subject reference) with aspect ratio control
• Up to 9 output images per request
• Up to 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

To use MiniMax for image generation, set it as the image generation provider:

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

The plugin uses the same MINIMAX_API_KEY or OAuth auth as the text models. No additional configuration is needed if MiniMax is already set up.

Both minimax and minimax-portal register image_generate with the same image-01 model. API-key setups use MINIMAX_API_KEY; OAuth setups can use the bundled minimax-portal auth path instead.

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. 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.

When onboarding or API-key setup writes explicit models.providers.minimax entries, OpenClaw materializes MiniMax-M2.7 and MiniMax-M2.7-highspeed as text-only chat models. Image understanding is exposed separately through the plugin-owned MiniMax-VL-01 media provider.

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
• Supported bundled model ids include 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, and speech-01-turbo.
• Auth resolution is 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 such as Feishu and Telegram are transcoded from MiniMax MP3 to 48kHz Opus with ffmpeg, because 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.

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 music model: minimax-portal/music-2.6
• Also supports minimax/music-2.5 and minimax/music-2.0
• Prompt controls: lyrics, instrumental, durationSeconds
• Output format: mp3
• Session-backed runs detach through the shared task/status flow, including action: "status"

To use MiniMax as the default music provider:

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

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 video model: minimax-portal/MiniMax-Hailuo-2.3
• Modes: text-to-video and single-image reference flows
• Supports aspectRatio and resolution

To use MiniMax as the default video provider:

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

Image understanding

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

That is why automatic media routing can use MiniMax image understanding even when the bundled text-provider catalog still shows text-only M2.7 chat refs.

Web search

The MiniMax plugin also registers web_search through the MiniMax Token Plan search API.

• 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.*.

Advanced configuration

This prevents MiniMax's streaming endpoint from emitting `reasoning_content` in OpenAI-style delta chunks, which would leak internal reasoning into visible output.

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

Notes

• Model refs follow the auth path:
  • API-key setup: minimax/<model>
  • OAuth setup: minimax-portal/<model>
• Default chat model: MiniMax-M2.7
• Alternate chat model: MiniMax-M2.7-highspeed
• Onboarding and direct API-key setup write text-only model definitions for 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-M2.7 or openclaw models set minimax-portal/MiniMax-M2.7

Troubleshooting

- Upgrading to **2026.1.12** (or run from source `main`), then restarting the gateway.
- 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-M2.7` or `minimax/MiniMax-M2.7-highspeed`
- OAuth path: `minimax-portal/MiniMax-M2.7` or `minimax-portal/MiniMax-M2.7-highspeed`

Then recheck with:

```bash
openclaw models list
```
