M2 for AI Coding Tools

MiniMax-M2 exposes both OpenAI-compatible (chat completions) and Claude-compatible (messages) endpoints, making it simple to drop into existing AI coding workflows. This guide walks through common tools and configuration patterns.

1. Claude-Code (Recommended)

Claude Code reads its provider configuration from ~/.claude/settings.json. In this file, add or update the env field as shown below. Set MINIMAX_API_KEY to the API key obtained from the minimax-m2.com.

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://minimax-m2.com/api/",
    "ANTHROPIC_AUTH_TOKEN": "<MINIMAX_API_KEY>",
    "API_TIMEOUT_MS": "3000000",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1,
    "ANTHROPIC_MODEL": "MiniMax-M2",
    "ANTHROPIC_SMALL_FAST_MODEL": "MiniMax-M2",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "MiniMax-M2",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "MiniMax-M2",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "MiniMax-M2"
  }
}

Save the file and restart Claude Code. Every inline edit, “fix”, or chat request will now hit https://minimax-m2.com/api/v1/messages with the Anthropic-compatible schema.

2. Codex

Install codex

npm i -g @openai/codex

Configure MiniMax API

1. Add the following configuration to the .codex/config.toml file:

[model_providers.minimax]
name = "MiniMax Chat Completions API"
base_url = "https://minimax-m2.com/api/v1"
env_key = "MINIMAX_API_KEY"
wire_api = "chat"
requires_openai_auth = false
request_max_retries = 4
stream_max_retries = 10
stream_idle_timeout_ms = 300000

[profiles.m2]
model = "codex-MiniMax-M2"
model_provider = "minimax"

2. Set the API key using environment variables in the current terminal session for security reasons. Use the API key obtained from the minimax-m2.com as the value for MINIMAX_API_KEY.

export MINIMAX_API_KEY="<MINIMAX_API_KEY>"

3. Start the Codex CLI with the specified profile.

codex --profile m2
