Ai Model Router V2

Automatically routes requests between local and cloud AI models based on task complexity and privacy, with auto-detection and context tracking.

AI Model Router

Compact, intelligent model routing that just works.

Quick Start

# Install
npx clawhub@latest install ai-model-router

# First run - auto-detects your models
python3 skill/core/router.py "What is Python?"

# List available models
python3 skill/core/router.py --list

How It Works

Your Request → Analyze → Select Model
                          ↓
                    Simple? → Primary (fast/cheap)
                    Complex? → Secondary (capable)
                    Private? → Primary (forced)

Scoring (from model-router-premium)

Pattern	Points
Microservices, architecture	+10
Design, implement, optimize	+5
Explain, analyze, compare	+3
Syntax, example, "what is"	-3

Threshold: 5 (simple vs complex)

Features

Feature	Status
Auto-detect local models	✓ (Ollama, LM Studio)
Cloud model registry	✓ (7 built-in)
Privacy detection	✓ (API keys, passwords)
Context tracking	✓ (conversations)
JSON config	✓ (optional)
CLI interface	✓
Core code size	~200 lines

CLI

# Route a task
python3 skill/core/router.py "Design a system"
python3 skill/core/router.py "What is a for loop?"

# Options
--json                    # JSON output
--force primary           # Force primary model
--list                    # List all models
--status                  # Show status

Python API

from skill.core.router import RouterCore

router = RouterCore()
result = router.route("Design microservices")

print(result.model_name)   # "Claude Opus 4"
print(result.reason)        # "complex_task(score=15)"
print(result.confidence)    # 0.75

Configuration (Optional)

Create ~/.model-router/models.json:

{
  "primary_model": {"id": "ollama:llama3:8b"},
  "secondary_model": {"id": "anthropic:claude-opus-4"},
  "models": [...]
}

Without config: Auto-detects local + uses cloud registry.

Privacy Protection

Automatically forces primary (local) when sensitive data detected:

• API keys (sk-..., api_key)
• Passwords (password, passwd)
• Tokens (bearer, secret)
• Emails, SSN, credit cards

Files

• core/router.py - Core routing engine (~200 lines)
• modules/detector.py - Auto-detection (optional)
• modules/context.py - Context tracking (optional)

Inspired By

• model-router-premium: Simple scoring logic, cost-aware routing
• Model Router v1: Full feature set, documentation

This version combines:

• The simplicity of model-router-premium (~200 lines)
• The features of ai-model-router (privacy, auto-detect, context)
