FreeModel

Stop paying Claude prices for every task. Route coding to DeepSeek, reasoning to Qwen, writing to Gemini — automatically. One API key, 25+ platforms, the right model every time.

FreeModel is a model router for Claude Code. It looks at what you're doing — writing code, analyzing data, translating text — and picks the best model for that specific task. Not just the cheapest. Not just the most popular. The one that actually scores highest on the relevant benchmarks.

---

Why this exists

Every model router does the same thing: "route cheap prompts to cheap models." They classify by complexity (simple → Haiku, complex → Opus) and call it a day.

FreeModel answers a different question: which model actually performs well on this type of task?

Other routers:                FreeModel:
"How hard is this?"           "What kind of task is this?"
         ↓                              ↓
  simple / medium / hard        coding / reasoning / writing
         ↓                              ↓
  pick cheaper model            pick model that scores highest
  at same complexity            on this task type's benchmarks

The difference is data. FreeModel scores every model across six dimensions (Code, Knowledge, Math, Instruction, Safety, Efficiency) using 18 public benchmarks — LiveCodeBench, MMLU-Pro, MATH-500, IFEval, SimpleQA, and more. The scores are public at model.leyijian.com/classification.html.

How it works

Tier system (L1–L5)

Every model gets a tier based on six-dimension benchmark scores — not marketing copy, not vibes.

Tier	Label	Threshold	Example
L1	Specialist	single-dim excellence	DeepSeek-R1 (Reasoning 95)
L2	Professional	≥70 composite	Claude Opus 4, GPT-5
L3	Competent	≥55 composite	Qwen3-Max, DeepSeek-V4
L4	Capable	≥35 composite	GLM-4-Flash, ERNIE-Speed
L5	Basic	<35 composite	Small/fast models

Task auto-detection

6 task types detected from the user's prompt before routing:

• coding — 写代码、debug、爬虫、API、build、修复
• reasoning — 分析、数学、架构、安全审计、规划
• writing — 翻译、写作、总结、报告、文档
• creative — 头脑风暴、命名、设计、营销
• chat — 问答、推荐、对比、讨论 (default)
• multimodal — 图片、OCR、视频

Task type → filter to models that score well on relevant benchmarks → pick best price/performance.

Scoring dimensions

Quick start

Option 1: npx (recommended)

Add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "freemodel": {
      "command": "npx",
      "args": ["-y", "freemodel-mcp"],
      "env": {
        "FREEMODEL_KEY": "sk-your-key"
      }
    }
  }
}

Get a key at model.leyijian.com → Settings → API Keys.

Option 2: git clone

git clone https://github.com/yummy342/freemodel-mcp.git
cd freemodel-mcp && npm install

{
  "mcpServers": {
    "freemodel": {
      "command": "node",
      "args": ["/path/to/freemodel-mcp/server.js"],
      "env": {
        "FREEMODEL_KEY": "sk-your-key"
      }
    }
  }
}

MCP Tools

Tool	What it does
freemodel_key_health	Subscription status, platform health, recommended model
freemodel_status	Session summary: active model, healthy count
freemodel_models	List your available platforms and models
freemodel_recommend	Describe a task → get 2-3 model picks with reasons
freemodel_run	Execute on a specific model (platform + model name)

With the skill (recommended)

Install the Claude Code skill for full auto-routing:

1. Copy skill.md to ~/.claude/skills/freemodel/skill.md
2. Claude Code auto-loads it on startup
3. Every task is auto-classified → routed to the best model → executed

The skill adds: subscription priority routing, platform health sorting, quota exhaustion prevention, task-type auto-detection, and model fallback chains.

What you need

1. A FreeModel API key (get one here)
2. Add platform keys in the dashboard (DeepSeek, Alibaba, etc.)
3. Node.js ≥ 18

That's it. No API keys in config files — everything lives in your FreeModel account, encrypted.

---

Privacy

This is a local relay. Prompts go from your machine → FreeModel API → target platform. No telemetry, no analytics. Your platform API keys stay encrypted in your FreeModel account.
