MiniMax

The minimax provider routes to MiniMax’s models. It exposes an OpenAI-compatible endpoint for chat, streaming, and embeddings, and a native Anthropic-compatible endpoint for Anthropic-format passthrough. Authentication is a bearer token on both.

Configuration

[providers.minimax]    # section name doubles as kind; add `kind = "minimax"` only if you rename it
api_key = "${MINIMAX_API_KEY}"
models = ["MiniMax-M2"]

Defaults, no base_url needed:

• OpenAI-compatible: https://api.minimax.io/v1
• Anthropic-compatible: https://api.minimax.io/anthropic/v1 (the /v1/messages path the Anthropic SDK / Claude Code resolve from ANTHROPIC_BASE_URL)

Set base_url to override the OpenAI-compatible origin (e.g. the api.minimaxi.com region).

Usage

curl http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "MiniMax-M2",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Anthropic-format requests are served natively by MiniMax’s Anthropic-compatible endpoint rather than translated.

Supported Endpoints

• Chat completions (streaming and non-streaming)
• Embeddings
• Anthropic Messages (native passthrough, streaming and non-streaming)
• Tool/function calling

Limitations

• The Anthropic-compatible endpoint reports a smaller context_window in model metadata than some MiniMax models actually support; clients that trust that metadata (e.g. Claude Code) may cap their budget early.
