Usage

Set your API key

Get your API key from the MiniMax Platform.

There are three ways to set your API key (in order of priority):

Option 1: Using /login (Recommended)

The easiest way is to use pi's built-in login command:

pi -e ./pi-minimax-provider
/login

This will prompt you to enter your API key, which is then securely stored in ~/.pi/agent/auth.json.

Option 2: Edit auth.json manually

Add your API key directly to the auth file:

{
  "providers": {
    "minimax": {
      "access": "your-api-key-here",
      "expires": 1935753600000
    }
  }
}

Option 3: Environment variable

export MINIMAX_API_KEY=your-api-key-here
pi -e ./pi-minimax-provider

Run pi with the extension

# Using local path
pi -e ./path/to/pi-provider-minimax

# Using global install
pi -e $(npm root -g)/pi-provider-minimax

Select a model

In pi's interactive mode:

/model MiniMax-M2.7

Or use the model selector UI.

Pricing

Pricing is approximate and in USD per million tokens:
