Model Router

Intelligent AI model routing across multiple providers for optimal cost-performance balance.

Automatically select the best model for any task based on complexity, type, and your preferences. Support for 6 major AI providers with secure API key management and interactive configuration.

🎯 What It Does

•Analyzes tasks and classifies them by type (coding, research, creative, simple, etc.)
•Routes to optimal models from your configured providers
•Optimizes costs by using cheaper models for simple tasks
•Secures API keys with file permissions (600) and isolated storage
•Provides recommendations with confidence scoring and reasoning

🚀 Quick Start

Step 1: Run the Setup Wizard

bash

cd skills/model-router
python3 scripts/setup-wizard.py

The wizard will guide you through:

•Provider setup - Add your API keys (Anthropic, OpenAI, Gemini, etc.)
•Task mappings - Choose which model for each task type
•Preferences - Set cost optimization level

Step 2: Use the Classifier

bash

# Get model recommendation for a task
python3 scripts/classify_task.py "Build a React authentication system"

# Output:
# Recommended Model: claude-sonnet
# Confidence: 85%
# Cost Level: medium
# Reasoning: Matched 2 keywords: build, system

Step 3: Route Tasks with Sessions

bash

# Spawn with recommended model
sessions_spawn --task "Debug this memory leak" --model claude-sonnet

# Use aliases for quick access
sessions_spawn --task "What's the weather?" --model haiku

📊 Supported Providers

🎛️ Task Type Mappings

Default routing (customizable via wizard):

Task Type	Default Model	Why
`simple`	glm-4.5-air	Fastest, cheapest for quick queries
`coding`	claude-sonnet-4-5	Excellent code understanding
`research`	claude-sonnet-4-5	Balanced depth and speed
`creative`	claude-opus-4-5	Maximum creativity
`math`	o1-mini	Specialized reasoning
`vision`	gemini-1.5-flash	Fast multimodal
`chinese`	glm-4.7	Optimized for Chinese
`long_context`	gemini-1.5-pro	Up to 2M tokens

💰 Cost Optimization

Aggressive Mode

Always uses the cheapest capable model:

•Simple → glm-4.5-air (~10% cost)
•Coding → claude-haiku-4-5 (~25% cost)
•Research → claude-sonnet-4-5 (~50% cost)

Savings: 50-90% compared to always using premium models

Balanced Mode (Default)

Considers cost vs quality:

•Simple tasks → Cheap models
•Critical tasks → Premium models
•Automatic escalation if cheap model fails

Quality Mode

Always uses the best model regardless of cost

🔒 Security

API Key Storage

code

~/.model-router/
├── config.json       # Model mappings (chmod 600)
└── .api-keys         # API keys (chmod 600)

Features:

•File permissions restricted to owner (600)
•Isolated from version control
•Encrypted at rest (via OS filesystem encryption)
•Never logged or printed

Best Practices

•Never commit .api-keys to version control
•Use environment variables for production deployments
•Rotate keys regularly via the wizard
•Audit access with ls -la ~/.model-router/

📖 Usage Examples

Example 1: Cost-Optimized Workflow

bash

# Classify task first
python3 scripts/classify_task.py "Extract prices from this CSV"

# Result: simple task → use glm-4.5-air
sessions_spawn --task "Extract prices" --model glm-4.5-air

# Then analyze with better model if needed
sessions_spawn --task "Analyze price trends" --model claude-sonnet

Example 2: Progressive Escalation

bash

# Try cheap model first (60s timeout)
sessions_spawn --task "Fix this bug" --model glm-4.5-air --runTimeoutSeconds 60

# If fails, escalate to premium
sessions_spawn --task "Fix complex architecture bug" --model claude-opus

Example 3: Parallel Processing

bash

# Batch simple tasks in parallel with cheap model
sessions_spawn --task "Summarize doc A" --model glm-4.5-air &
sessions_spawn --task "Summarize doc B" --model glm-4.5-air &
sessions_spawn --task "Summarize doc C" --model glm-4.5-air &
wait

Example 4: Multimodal with Gemini

bash

# Vision task with 2M token context
sessions_spawn --task "Analyze these 100 images" --model gemini-1.5-pro
