n8n-nodes-minimax

中文文档

This is an n8n community node that lets you use MiniMax AI in your n8n workflows.

MiniMax provides powerful large language models including MiniMax-M2.5, M2.1, M2 and M2-her for chat completion, reasoning, code generation and roleplay scenarios.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

npm package: n8n-nodes-minimax

Nodes

This package provides two nodes:

| Node | Type | Description | |------|------|-------------| | MiniMax | Action node | Standalone chat completion node for direct API calls in workflows | | MiniMax Chat Model | AI sub-node | Language model node that plugs into n8n AI Agent, AI Chain and other AI nodes |

Credentials

1. Create an API Key from the MiniMax platform:
   • International: platform.minimax.io
   • China (中国版): platform.minimaxi.com
2. In n8n, create a new MiniMax API credential.
3. Choose your API Type (4 options):

| API Type | Endpoint | Billing | Use Case | |----------|----------|---------|----------| | International — Standard | api.minimax.io | Per token | Global users, pay-as-you-go | | International — Coding Plan | api.minimax.io/anthropic | Subscription | Global users, AI coding tools | | 中国版 — Standard | api.minimaxi.com | Per token | China mainland users, pay-as-you-go | | 中国版 — Coding Plan | api.minimaxi.com/anthropic | Subscription | China mainland users, AI coding tools |

4. Paste your API key.
5. (Standard only) Optionally enter your Group ID for legacy v1 API calls.

Important:

• International and China editions use different domains and different API keys — they are NOT interchangeable.
• Standard and Coding Plan use different API keys — they are NOT interchangeable either.

Supported Models

| Model | Description | |-------|-------------| | MiniMax-M2.5 | Peak performance, ~60 tokens/sec | | MiniMax-M2.5 Highspeed | Same M2.5 performance, ~100 tokens/sec | | MiniMax-M2.1 | Enhanced programming capabilities | | MiniMax-M2.1 Highspeed | Faster variant, ~100 tokens/sec | | MiniMax-M2 | Agentic capabilities, advanced reasoning | | M2-her | Multi-character roleplay & dialogue |

Usage

MiniMax (Action Node)

Use this node for standalone API calls in a workflow:

1. Add a MiniMax node to your workflow.
2. Select Chat > Complete as the resource and operation.
3. Choose a model and add your prompt messages.
4. Optionally configure temperature, top_p, max_tokens and other parameters.

MiniMax Chat Model (AI Sub-node)

Use this node as a language model inside AI Agent, AI Chain or other AI nodes:

1. Add an AI Agent (or AI Chain) node to your workflow.
2. Click the Model slot and select MiniMax Chat Model.
3. Configure your MiniMax API credentials and choose a model.
4. The model will be used by the Agent for reasoning, tool calling and response generation.

Tip: MiniMax-M2.5 and M2 support function calling / tool use, making them work well with AI Agents that need to invoke tools (e.g. MCP, HTTP, code execution).

Options (Action Node)

| Option | Standard | Coding Plan | Description | |--------|:---:|:---:|-------------| | Max Tokens | ✅ | ✅ | Limit the length of generated text | | Temperature | ✅ | ✅ | Control randomness (0–2) | | Top P | ✅ | ✅ | Nucleus sampling diversity control | | Frequency Penalty | ✅ | — | Reduce repetition of tokens | | Presence Penalty | ✅ | — | Encourage exploring new topics | | Response Format | ✅ | — | Text or JSON Object output | | Simplify | ✅ | ✅ | Return only essential message content |
