MiniMax-M2.5

Model ID: MiniMax-M2.5 Released: February 12, 2026

Major Improvements Over M2.1

🏗️ Architect-Style Planning

M2.5 actively decomposes and plans features, structure, and UI design before writing any code. This spec-writing tendency emerged during training — the model thinks like an experienced software architect.

💻 SOTA Coding Performance

Trained on 13+ languages (Go, C, C++, TypeScript, Rust, Kotlin, Python, Java, JavaScript, PHP, Lua, Dart, Ruby) across 200,000+ real-world environments. Covers the entire development lifecycle: 0-to-1 system design, 1-to-10 development, 10-to-90 feature iteration, and 90-to-100 code review and testing. Full-stack across Web, Android, iOS, and Windows.

• SWE-Bench Verified: 80.2% (SOTA)
• Multi-SWE-Bench: 51.3%
• On Droid: 79.7 (> Opus 4.6's 78.9)
• On OpenCode: 76.1 (> Opus 4.6's 75.9)
• 37% faster than M2.1 on SWE-Bench, matching Claude Opus 4.6 speed

🔍 Industry-Leading Search & Tool Calling

Best-in-class performance on BrowseComp (76.3% with context management) and Wide Search. Uses ~20% fewer rounds than M2.1 to achieve better results — more efficient reasoning paths, not just correct answers.

📊 Office & Finance Workflows

Excels at Excel-based tasks (MEWC benchmark), financial modeling, and complex multi-step business processes. Handles composite instruction constraints for real enterprise scenarios.

⚡ Speed & Cost

Completes SWE-Bench Verified 37% faster than M2.1. It costs just $1 to run continuously for an hour at 100 tokens/s, or $0.30 at 50 tokens/s.

Benchmark Highlights

• SWE-Bench Verified: 80.2% (SOTA)
• Multi-SWE-Bench: 51.3%

How to Specify Models

Pass the model field in your API request:

Chat Completions (OpenAI format)

{
  "model": "MiniMax-M2.5",
  "messages": [
    { "role": "user", "content": "Write a Rust function for async HTTP requests" }
  ]
}

Messages API (Claude format)

{
  "model": "MiniMax-M2.5",
  "system": "You are an expert Android developer.",
  "messages": [
    { "role": "user", "content": "Implement a Material 3 bottom sheet" }
  ],
  "max_tokens": 2048
}

Default Behavior

Defaults are channel-specific:

• Web chat UI defaults to MiniMax-M2.5
• OpenAI-compatible API (POST /api/v1/chat/completions) defaults to MiniMax-M2 when model is omitted
• Messages API (POST /api/v1/messages) defaults to MiniMax-M2 when model is omitted

This preserves backward compatibility for existing API clients while keeping the hosted chat experience on M2.5.

Pricing

Baseline launch-window pricing for MiniMax-M2, MiniMax-M2.1, and MiniMax-M2.5:

MiniMax-M2.7 and MiniMax-M3 may use different price profiles depending on deployment configuration. Always check GET /api/v1/models for effective model-level rates before cost planning.

Usage charges appear in your billing dashboard with per-model breakdowns, allowing you to track consumption across M2, M2.1, M2.5, M2.7, and M3 independently.

Recommended Parameters

For optimal performance with all models:

{
  "temperature": 1.0,
  "top_p": 0.95,
  "top_k": 40
}

Adjust temperature downward (0.3–0.7) for deterministic outputs in compliance-sensitive or production-critical scenarios.

4. Preserve content blocks: Keep complete assistant blocks in multi-turn tool-use conversations
5. Confirm effective billing: Query GET /api/v1/models before rollout

Switching to M2.7

1. Update the model field: Change your request model to "MiniMax-M2.7"
2. No endpoint changes required: OpenAI-compatible and Claude-compatible contracts remain unchanged
3. Confirm live pricing/capabilities: Query GET /api/v1/models in your deployment before rollout
4. Roll out safely: Start with a subset of traffic, compare quality/cost, then expand

Switching to M2.5

1. Update the model field: Change "MiniMax-M2.1" to "MiniMax-M2.5" in your request body
2. No API changes required: All models support identical endpoint contracts
3. Leverage 200K context: M2.5 supports 200K tokens, up from 128K in M2/M2.1
4. Expect architect-style output: M2.5 may produce spec/plan documents before writing code — this is by design
5. Monitor speed improvements: M2.5 completes agentic tasks 37% faster than M2.1

Switching from M2 to M2.1

1. Update the model field: Change "MiniMax-M2" to "MiniMax-M2.1" in your request body
2. No API changes required: Both models support identical endpoint contracts
3. Monitor token usage: M2.1's concise responses may reduce your token consumption
4. Test prompts: M2.1's enhanced capabilities may produce different (often better) outputs for the same inputs
