Config example

{
  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,
          },
        ],
      },
    },
  },
}

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.

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

Configure via `openclaw configure`

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

Launch the wizard

openclaw configure

Select Model/auth

Choose Model/auth from the menu.

Choose a MiniMax auth option

Pick one of the available MiniMax options:

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

Pick your default model

Select your default model when prompted.

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.

See 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
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.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 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",
      },
    },
  },
}

See 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 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",
      },
    },
  },
}

See 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
`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 still shows text-only M2.7 chat refs.

Web search

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

Provider id: minimax
Structured results: titles, URLs, snippets, related queries
Preferred env var: MINIMAX_CODE_PLAN_KEY
Accepted env alias: MINIMAX_CODING_API_KEY
Compatibility fallback: MINIMAX_API_KEY when it already points at a coding-plan token
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 still steer region indirectly through models.providers.minimax-portal.baseUrl

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

See MiniMax Search for full web search configuration and usage.

Advanced configuration

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

Thinking defaults

On api: "anthropic-messages", OpenClaw injects thinking: { type: "disabled" } unless thinking is already explicitly set in params/config.This prevents MiniMax’s streaming endpoint from emitting reasoning_content in OpenAI-style delta chunks, which would leak internal reasoning into visible output.

Fast mode

/fast on or params.fastMode: true rewrites MiniMax-M2.7 to MiniMax-M2.7-highspeed on the Anthropic-compatible stream path.

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.

{
  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 details

Coding Plan usage API: https://api.minimaxi.com/v1/api/openplatform/coding_plan/remains (requires a coding plan key).
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.

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

"Unknown model: minimax/MiniMax-M2.7"

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-M2.7 or minimax/MiniMax-M2.7-highspeed
OAuth path: minimax-portal/MiniMax-M2.7 or minimax-portal/MiniMax-M2.7-highspeed
