- description
- Intelligent AI model router that automatically switches between two configured models (local for simple tasks, cloud for complex ones). Detects local models (Ollama, LM Studio) automatically, routes based on task complexity and privacy. Use when users ask to "switch model", "use local/cloud model", or mention API keys/passwords (triggers privacy mode). Trigger on: sensitive data detection (forces local), complex tasks like "design architecture" (uses cloud), or configuration requests.

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 --listHow 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 statusPython 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) # 0.75Configuration (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
