MiniMax

MiniMax

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

Model lineup

• MiniMax-M2.7: default hosted text model.
• MiniMax-M2.7-highspeed: faster M2.7 text tier.
• image-01: image generation model (generate and image-to-image editing).

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.
• 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.

Choose a setup

MiniMax OAuth (Coding Plan) - recommended

Best for: quick setup with MiniMax Coding Plan via OAuth, no API key required.

Enable the bundled OAuth plugin and authenticate:

openclaw plugins enable minimax  # skip if already loaded.
openclaw gateway restart  # restart if gateway is already running
openclaw onboard --auth-choice minimax-portal

You will be prompted to select an endpoint:

• Global - International users (api.minimax.io)
• CN - Users in China (api.minimaxi.com)

See the MiniMax plugin package README in the OpenClaw repo for details.

MiniMax M2.7 (API key)

Best for: hosted MiniMax with Anthropic-compatible API.

Configure via CLI:

• Run openclaw configure
• Select Model/auth
• Choose a MiniMax auth option

{
  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: 0.03, cacheWrite: 0.12 },
            contextWindow: 200000,
            maxTokens: 8192,
          },
          {
            id: "MiniMax-M2.7-highspeed",
            name: "MiniMax M2.7 Highspeed",
            reasoning: true,
            input: ["text"],
            cost: { input: 0.3, output: 1.2, cacheRead: 0.03, cacheWrite: 0.12 },
            contextWindow: 200000,
            maxTokens: 8192,
          },
        ],
      },
    },
  },
}

MiniMax M2.7 as 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"],
      },
    },
  },
}

Configure via openclaw configure

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

1. Run openclaw configure.
2. Select Model/auth.
3. Choose a MiniMax auth option.
4. Pick your default model when prompted.

Configuration options

• 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.

Notes

• Model refs are minimax/<model>.
• Default text model: MiniMax-M2.7.
• Alternate text model: MiniMax-M2.7-highspeed.
• Coding Plan usage API: https://api.minimaxi.com/v1/api/openplatform/coding_plan/remains (requires a coding plan key).
• Update pricing values in models.json if you need exact cost tracking.
• Referral link for MiniMax Coding Plan (10% off): https://platform.minimax.io/subscribe/coding-plan?code=DbXJTRClnb&source=link
• See /concepts/model-providers for provider rules.
• Use openclaw models list and openclaw models set minimax/MiniMax-M2.7 to switch.

Troubleshooting

”Unknown model: minimax/MiniMax-M2.7”

This usually means the MiniMax provider isn’t configured (no 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 models.providers.minimax block manually, or
• Setting MINIMAX_API_KEY (or a MiniMax auth profile) so the provider can be injected.

Make sure the model id is case‑sensitive:

• minimax/MiniMax-M2.7
• minimax/MiniMax-M2.7-highspeed

Then recheck with:
