Official: MiniMax M2.1 Configuration for AI Coding Tools

# MiniMax M2.1 for AI Coding Tools

Official configuration guide for using MiniMax-M2.1 with Claude Code, Cline, Kilo Code, Roo Code, and other agentic coding assistants.

## Quick Start

### API Configuration

**Base URL (International):**
```
https://api.minimax.io/anthropic
```

**Base URL (China):**
```
https://api.minimaxi.com/anthropic
```

### Environment Setup

Clear any conflicting variables first:

```bash
unset ANTHROPIC_AUTH_TOKEN
unset ANTHROPIC_BASE_URL
```

Then set MiniMax credentials:

```bash
export ANTHROPIC_API_KEY="your-minimax-api-key"
export ANTHROPIC_BASE_URL="https://api.minimax.io/anthropic"
export API_TIMEOUT_MS=3000000  # 50 min for extended reasoning
```

## Claude Code Configuration

Add to `~/.claude/settings.json`:

```json
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.minimax.io/anthropic",
    "API_TIMEOUT_MS": "3000000"
  },
  "model": "MiniMax-M2.1",
  "smallFastModel": "MiniMax-M2.1"
}
```

## Recommended Parameters

MiniMax recommends these inference settings:

| Parameter | Value |
|-----------|-------|
| Temperature | 1.0 |
| Top-p | 0.95 |
| Top-k | 40 |

## System Prompt

Default system prompt:

```
You are a helpful assistant. Your name is MiniMax-M2.1 and is built by MiniMax.
```

## Interleaved Thinking

M2.1 uses `<think>` blocks for reasoning before tool calls. This is enabled by default and improves multi-step problem solving.

**Important:** Preserve reasoning between turns to maintain performance. Don't strip `<think>` blocks from context.

## Tool Calling

M2.1 is optimized for agentic workflows:
- Robust tool use and instruction following
- Long-horizon planning
- Multi-step reasoning with transparency

## Cline / Kilo Code / Roo Code

These tools support native MiniMax provider integration. Use the secure prompt method instead of exposing API keys in config files.

## Troubleshooting

**Timeout errors:** Increase `API_TIMEOUT_MS` to at least 3000000 (50 minutes)

**Auth conflicts:** Ensure `ANTHROPIC_AUTH_TOKEN` is unset - it conflicts with `ANTHROPIC_API_KEY`

**Slow responses:** M2.1 uses extended thinking. This is normal for complex tasks.
