API guide

Chat completion

M2.5-Highspeed uses the same OpenAI-compatible v1/chat/completions endpoint as any TheRouter model. Simply set the model field to minimax/m2.5-highspeed.

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"minimax/m2.5-highspeed","messages":[{"role":"user","content":"Write a React component for a file uploader with drag-and-drop support."}]}'

Tool calling

M2.5-Highspeed supports parallel tool calls. Use the OpenAI SDK's tools API to define functions β€” the model will invoke them just like the standard variant, at higher throughput.

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "minimax/m2.5-highspeed",
    "messages": [{"role":"user","content":"What is the weather in Shanghai and Tokyo?"}],
    "tools": [{
      "type": "function",
      "function": {
        "name": "get_weather",
        "description": "Get weather for a city",
        "parameters": {
          "type": "object",
          "properties": {
            "location": {"type": "string", "description": "City name"}
          },
          "required": ["location"]
        }
      }
    }],
    "tool_choice": "auto"
  }'
