### Config example
```json5
{
env: { MINIMAX_API_KEY: "sk-..." },
agents: { defaults: { model: { primary: "minimax/MiniMax-M3" } } },
models: {
mode: "merge",
providers: {
minimax: {
baseUrl: "https://api.minimax.io/anthropic",
apiKey: "${MINIMAX_API_KEY}",
api: "anthropic-messages",
models: [
{

name: "MiniMax M3",
reasoning: true,
input: ["text", "image"],

},
{
id: "MiniMax-M2.7-highspeed",
name: "MiniMax M2.7 Highspeed",
reasoning: true,
input: ["text"],

contextWindow: 204800,
maxTokens: 131072,
},
],
},
},
},
}
```
<Warning>
On the Anthropic-compatible streaming path, OpenClaw disables MiniMax M2.x thinking by default unless you explicitly set `thinking` yourself. M2.x'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. MiniMax-M3 (and forward-compatible M3.x) is exempt from this default: M3 emits proper Anthropic thinking blocks and requires thinking active to produce visible content, so OpenClaw keeps M3 on the provider's omitted/adaptive thinking path.
</Warning>
<Note>
API-key setups use the `minimax` provider id. Model refs follow the form `minimax/MiniMax-M3`.

| `minimax-cn-oauth` | China OAuth (Coding Plan) |
| `minimax-global-api` | International API key |
| `minimax-cn-api` | China API key |
</Step>
<Step title="Pick your default model">
Select your default model when prompted.
</Step>
</Steps>
## 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:
```json5
{
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-M3`, `MiniMax-M2.7`, and
`MiniMax-M2.7-highspeed` as chat models. M3 advertises text and image input;
image understanding remains exposed separately through the plugin-owned
`MiniMax-VL-01` media provider.
<Note>
See [Image Generation](/tools/image-generation) for shared tool parameters, provider selection, and failover behavior.
</Note>
### 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.
| 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.speakerVoiceId` | `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 music model: `minimax-portal/music-2.6`
- Also supports `minimax/music-2.5` and `minimax/music-2.0`
- Prompt controls: `lyrics`, `instrumental`
- Output format: `mp3`
- Session-backed runs detach through the shared task/status flow, including `action: "status"`
To use MiniMax as the default music provider:
```json5
{
agents: {
defaults: {
musicGenerationModel: {
primary: "minimax/music-2.6",
},
},
},
}
```
<Note>
See [Music Generation](/tools/music-generation) for shared tool parameters, provider selection, and failover behavior.
</Note>
### 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:
```json5
{
agents: {
defaults: {
videoGenerationModel: {
primary: "minimax/MiniMax-Hailuo-2.3",
},
},
},
}
```
<Note>
See [Video Generation](/tools/video-generation) for shared tool parameters, provider selection, and failover behavior.
</Note>
### Image understanding
The MiniMax plugin registers image understanding separately from the text
catalog:
| Provider ID | Default image model |
| ---------------- | ------------------- |
| `minimax` | `MiniMax-VL-01` |
| `minimax-portal` | `MiniMax-VL-01` |
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.
### 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.*`.
<Note>
See [MiniMax Search](/tools/minimax-search) for full web search configuration and usage.
</Note>
## Advanced configuration
<AccordionGroup>
<Accordion title="Configuration options">
| 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 |
</Accordion>
<Accordion title="Thinking defaults">
On `api: "anthropic-messages"`, OpenClaw injects `thinking: { type: "disabled" }` for MiniMax M2.x models unless thinking is already explicitly set in params/config.
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 emits proper Anthropic thinking blocks and returns an empty `content` array with `stop_reason: "end_turn"` when thinking is disabled, so the wrapper keeps M3 on the provider's omitted/adaptive thinking path.
</Accordion>
<Accordion title="Fast mode">
`/fast on` or `params.fastMode: true` rewrites `MiniMax-M2.7` to `MiniMax-M2.7-highspeed` on the Anthropic-compatible stream path.
</Accordion>
<Accordion title="Fallback example">
**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"],
},
},
},
}
```
</Accordion>
<Accordion title="Coding Plan usage details">
- 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`, and `minimax-portal` as the same MiniMax quota surface, and prefer stored MiniMax OAuth before falling back to Coding Plan key env vars.
</Accordion>
</AccordionGroup>
## Notes
- Model refs follow the auth path:
- API-key setup: `minimax/<model>`
- OAuth setup: `minimax-portal/<model>`
- 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`

## Troubleshooting
<AccordionGroup>
<Accordion title='"Unknown model: minimax/MiniMax-M3"'>
This usually means the **MiniMax provider is not configured** (no matching provider entry and no MiniMax auth profile/env key found). A fix for this detection is in **2026.1.12**. Fix by:
- 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-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
```
