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", "image"],
            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", "image"],
            cost: { input: 0.6, output: 2.4, cacheRead: 0.06, cacheWrite: 0.375 },
            contextWindow: 204800,
            maxTokens: 131072,
          },
        ],
      },
    },
  },
}

On the Anthropic-compatible streaming path, FluffBuzz 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 `fluffbuzz configure`

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

Launch the wizard

fluffbuzz 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. When onboarding or API-key setup writes explicit models.providers.minimax entries, FluffBuzz materializes MiniMax-M2.7 and MiniMax-M2.7-highspeed with input: ["text", "image"]. The built-in bundled MiniMax text catalog itself stays text-only metadata until that explicit provider config exists. 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.

Music generation

The bundled minimax plugin also registers music generation through the shared music_generate tool.

Default music model: minimax/music-2.5+
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-2.5+",
      },
    },
  },
}

See Music Generation for shared tool parameters, provider selection, and failover behavior.

Video generation

The bundled minimax plugin also registers video generation through the shared video_generate tool.

Default video model: minimax/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", FluffBuzz 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).
FluffBuzz 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 FluffBuzz inverts them. Count-based fields win when present.
When the API returns model_remains, FluffBuzz 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 explicit model definitions with input: ["text", "image"] for both M2.7 variants
The bundled provider catalog currently exposes the chat refs as text-only metadata until explicit MiniMax provider config exists
Update pricing values in models.json if you need exact cost tracking
Use fluffbuzz models list to confirm the current provider id, then switch with fluffbuzz models set minimax/MiniMax-M2.7 or fluffbuzz 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 fluffbuzz 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
