"MiniMax M2 API Complete Guide: Build with MiniMax's Flagship Model"

MiniMax M2 is the flagship language model from MiniMax (also known as Hailuo AI), one of China's leading AI companies. With strong multilingual capabilities, competitive pricing, and impressive performance on both Chinese and English benchmarks, M2 has become a compelling alternative to Western frontier models — especially for applications targeting Asian markets.

This guide covers everything developers need to know to integrate MiniMax M2 into their applications.

What Is MiniMax M2?#

MiniMax is a Chinese AI company backed by Tencent, known for their Hailuo AI video generation platform and their language model series. M2 is their latest and most capable model, designed for both consumer and enterprise applications.

Key Features#

What Makes M2 Stand Out?#

1. 256K Context Window: One of the largest context windows available, ideal for document analysis and long conversations.

2. Bilingual Excellence: Unlike most Chinese models that sacrifice English quality, M2 performs competitively in both Chinese and English.

3. Cost-Effective: Significantly cheaper than GPT-5 or Claude Opus while delivering strong performance.

4. Hailuo Integration: Native integration with MiniMax's video and audio generation capabilities.

MiniMax M2 vs Alternatives#

Best for: Chinese-language applications, bilingual chatbots, long-context document processing, and cost-sensitive deployments.

How to Use MiniMax M2 API#

        {"role": "user", "content": "请写一篇关于人工智能在教育领域应用的文章，800字左右，包含具体案例。"}
    ],
    max_tokens=4096
)

print(response.choices[0].message.content)

Node.js Example#

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'your-crazyrouter-api-key',
  baseURL: 'https://api.crazyrouter.com/v1',
});

// Long context document analysis
const longDocument = '...'; // Your 100K+ token document

const response = await client.chat.completions.create({
  model: 'MiniMax-M2',
  messages: [
    {
      role: 'system',
      content: 'Analyze the following document and provide a structured summary with key findings.',
    },
    { role: 'user', content: longDocument },
  ],
  max_tokens: 4096,
});

console.log(response.choices[0].message.content);

cURL Example#

curl https://api.crazyrouter.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-crazyrouter-api-key" \
  -d '{
    "model": "MiniMax-M2",
    "messages": [
      {"role": "user", "content": "Compare React and Vue.js for a new project in 2026."}
    ],
    "max_tokens": 2048
  }'

Streaming Response#

stream = client.chat.completions.create(
    model="MiniMax-M2",
    messages=[
        {"role": "user", "content": "Write a detailed guide to setting up a Kubernetes cluster."}
    ],
    max_tokens=4096,
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)

Function Calling#

import json

tools = [
    {
        "type": "function",
        "function": {
            "name": "search_products",
            "description": "Search for products in the catalog",
            "parameters": {
                "type": "object",

                    "query": {"type": "string", "description": "Search query"},
                    "category": {"type": "string", "enum": ["electronics", "clothing", "food"]},
                    "max_price": {"type": "number", "description": "Maximum price in USD"}
                },
                "required": ["query"]
            }
        }

if response.choices[0].message.tool_calls:
    tool_call = response.choices[0].message.tool_calls[0]
    args = json.loads(tool_call.function.arguments)
    print(f"Function: {tool_call.function.name}")
    print(f"Arguments: {args}")

Cost Comparison for Common Tasks#

MiniMax M2 offers excellent value — comparable to GPT-5-mini pricing with stronger Chinese language capabilities.

Use Cases Where M2 Excels#

1. Bilingual Customer Support#

# M2 handles code-switching naturally
response = client.chat.completions.create(
    model="MiniMax-M2",
    messages=[
        {"role": "system", "content": "You are a bilingual customer support agent. Respond in the same language the customer uses."},
        {"role": "user", "content": "我想退货，order number是 #12345，但是I can't find the return page."}
    ],
    max_tokens=1024
)

2. Chinese Content Generation#

M2 produces natural, culturally appropriate Chinese content — better than most Western models that tend to produce "translated-sounding" Chinese.

3. Long Document Processing#

With 256K context, M2 can process entire books, legal documents, or codebases in a single request.

4. Asian Market Applications#

For apps targeting Chinese, Japanese, or Korean users, M2's multilingual Asian language support is a significant advantage.
