Model ID 
MiniMaxAI/MiniMax-M2.5

​
API Usage

MiniMax-M2.5 supports two API formats:
  • OpenAI-compatible: /v1/chat/completions endpoint
  • Anthropic-compatible: /v1/messages endpoint (with extended thinking support)

​
API Examples

​
OpenAI-Compatible Endpoint

Generate a model response using the chat completions endpoint.

​
Shell

curl --request POST \
  --url https://api.gmi-serving.com/v1/chat/completions \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer *************' \
  --data '{
    "model": "MiniMaxAI/MiniMax-M2.5",
    "messages": [
      {"role": "system", "content": "You are a helpful AI assistant with strong reasoning and coding ability."},
      {"role": "user", "content": "Explain how the Mixture-of-Experts architecture improves inference efficiency in large language models."}
    ],
    "max_tokens": 1024
  }'

​
Python

import requests
import json

url = "https://api.gmi-serving.com/v1/chat/completions"
headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_KEY"
}

payload = {
    "model": "MiniMaxAI/MiniMax-M2.5",
    "messages": [
        {"role": "system", "content": "You are a capable AI coding assistant"},
        {"role": "user", "content": "Refactor this multi-file Python module to make it async-ready"}
    ],
    "max_tokens": 1024
}

response = requests.post(url, headers=headers, json=payload)
print(json.dumps(response.json(), indent=2))

​
Anthropic-Compatible Endpoint (with Extended Thinking)

The /v1/messages endpoint provides access to the model’s reasoning process through the “thinking” content block. You can also use the Anthropic SDK directly by configuring the base URL. 
# Configure environment variables
export ANTHROPIC_BASE_URL=https://api.minimax.io/anthropic
export ANTHROPIC_API_KEY=${YOUR_API_KEY}

import anthropic

client = anthropic.Anthropic()

message = client.messages.create(
    model="MiniMax-M2.5",
    max_tokens=1000,
    system="You are a helpful assistant.",
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                    "text": "Hi, how are you?"
                }
            ]
        }
    ]
)

for block in message.content:
    if block.type == "thinking":
        print(f"Thinking:\n{block.thinking}\n")
    elif block.type == "text":
        print(f"Text:\n{block.text}\n")

​
Shell (Direct API)

curl --request POST \
  --url https://api.gmi-serving.com/v1/messages \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: *************' \
  --data '{
    "model": "MiniMaxAI/MiniMax-M2.5",
    "max_tokens": 1024,
    "messages": [
      {"role": "user", "content": "Solve this step by step: What is 23 * 47?"}
    ]
  }'
