How to use MiniMax M2 in Claude Code
MiniMax M2 a new open source model (open weight) that is specifically built for coding & agentic workflows.
They claim to be be as good as Sonnet 4 but at a fraction of the cost.
You can access the model via API.
In term of cost, it is Input tokens - $0.30/million and $1.20/million for output token.
But you can access it for free until November 7th.
Similar to GLM 4.6, they also has first class support for Anthropic like API response which means we can use it with our Claude Code
Getting Started
First, you need to get the MiniMax API key which you can get it platform
Claude Code CLI
Once you’re done, you can update it in ~/.claude/settings.json
{
"env": {
"ANTHROPIC_BASE_URL": "https://api.minimax.io/anthropic",
"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"
}
}
Make sure to replace your key in ANTHROPIC_AUTH_TOKEN. And as you can see we’re pretty much using MiniMax-M2 model for everything.
You can refer to their docs on how to use it in VS Code Extention, Cursor, Codex, Droid, etc
