MiniMax M2.7 Highspeed

minimaxminimax/m2.7-highspeed

API guide

Chat completion

Basic text generation via chat completions endpoint. Same interface as standard M2.7 but with accelerated token generation. Supports temperature, max_tokens, top_p, stop, and response_format (JSON mode).

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"minimax/m2.7-highspeed","messages":[{"role":"user","content":"Write a Rust function to parse CSV"}],"temperature":0.7,"max_tokens":4096}'

Streaming

M2.7 Highspeed is optimized for SSE streaming — at ~100 tokens/sec output, the streaming experience is noticeably snappier than standard M2.7. Set stream: true in the request body.

curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"minimax/m2.7-highspeed","messages":[{"role":"user","content":"Explain self-evolving AI"}],"stream":true}'

Function calling (tools)

M2.7 Highspeed supports tool_choice and tools for function calling. Identical function calling capability to standard M2.7 but with lower latency — ideal for agentic loops that call tools sequentially.
