Multi-Model Router for Agentic-Flow

Overview

The Multi-Model Router extends agentic-flow to work with multiple LLM providers beyond Anthropic's Claude, enabling cost optimization, provider diversity, and local model support.

🚀 Quick Start

1. Install

npm install -g agentic-flow@latest

2. Configure Environment

Add API keys to your .env file:

# Primary provider (Anthropic)
ANTHROPIC_API_KEY=sk-ant-...

# Multi-model gateway (OpenRouter)
OPENROUTER_API_KEY=sk-or-...

# Optional providers
OPENAI_API_KEY=sk-...
GOOGLE_API_KEY=...

3. Copy Configuration Template

cp router.config.example.json ~/.agentic-flow/router.config.json

4. Use Different Providers

# Use OpenRouter (default in example config)
npx agentic-flow --agent coder --task "Build REST API"

# Use specific provider
npx agentic-flow --provider openai --agent coder --task "Build REST API"

# Use specific model
npx agentic-flow --model gpt-4 --agent coder --task "Build REST API"

# Use local model
npx agentic-flow --provider ollama --model llama3:70b --agent coder --task "Build REST API"

🎯 Routing Strategies

1. Manual Routing

Explicitly select provider and model:

npx agentic-flow --provider openai --model gpt-4 --task "..."

2. Cost-Optimized Routing

Automatically select cheapest suitable provider:

{
  "routing": {
    "mode": "cost-optimized",
    "costOptimization": {
      "enabled": true,
      "maxCostPerRequest": 0.50
    }
  }
}

npx agentic-flow --router-mode cost-optimized --task "..."

3. Performance-Optimized Routing

Prioritize fastest provider:

{
  "routing": {
    "mode": "performance-optimized",
    "performance": {
      "targetLatency": 5000
    }
  }
}

4. Rule-Based Routing

Define custom routing rules:

{
  "routing": {
    "mode": "rule-based",
    "rules": [
      {
        "condition": {
          "agentType": ["coder", "reviewer"],
          "requiresTools": true
        },
        "action": {
          "provider": "anthropic",
          "model": "claude-3-5-sonnet-20241022"
        }
      },
      {
        "condition": {
          "privacy": "high"
        },
        "action": {
          "provider": "ollama",
          "model": "llama3:70b"
        }
      }
    ]
  }
}

💰 Cost Optimization

Track Costs

# View today's costs
npx agentic-flow router costs --period today

# View monthly costs
npx agentic-flow router costs --period month

# View costs by provider
npx agentic-flow router costs --by-provider

Set Budget Alerts

# Set daily budget
npx agentic-flow router config set routing.costOptimization.budgetAlerts.daily 10.00

# Set monthly budget
npx agentic-flow router config set routing.costOptimization.budgetAlerts.monthly 250.00

Cost Optimization Tips

1. Use cheaper models for simple tasks:

   npx agentic-flow --model gpt-3.5-turbo --agent researcher --task "Simple research"
   

2. Route via OpenRouter for automatic cost optimization:

   npx agentic-flow --provider openrouter --router-mode cost-optimized --task "..."
   

3. Use local models for development:

   npx agentic-flow --provider ollama --task "Development task"
   

🔧 Tool Calling Support

Provider Compatibility

Provider	Tool Calling	MCP Support	Format
Anthropic	✅ Full	✅ Native	Anthropic Tools
OpenAI	✅ Full	⚡ Translated	OpenAI Functions
OpenRouter	✅ Varies by model	⚡ Translated	Auto-detect
Ollama	⚠️ Limited	❌ Manual	Text-based
LiteLLM	✅ Full	⚡ Translated	Auto-detect

Enable Tool Translation

{
  "toolCalling": {
    "translationEnabled": true,
    "defaultFormat": "anthropic",
    "formatMapping": {
      "openai": "openai-functions",
      "openrouter": "auto-detect"
    }
  }
}

Using Tools with Different Providers

# Anthropic (native tool support)
npx agentic-flow --provider anthropic --agent coder --task "Use bash and file tools"

# OpenAI (translated tool support)
npx agentic-flow --provider openai --agent coder --task "Use bash and file tools"

# Ollama (text-based tools)
npx agentic-flow --provider ollama --agent coder --task "Use tools" --tool-mode text

🔒 Privacy & Security

Local-Only Mode

Route all requests to local models:

# Force local-only mode
npx agentic-flow --local-only --task "Confidential analysis"

Configure in router.config.json:

{
  "routing": {
    "mode": "rule-based",
    "rules": [
      {
        "condition": { "privacy": "high" },
        "action": { "provider": "ollama", "model": "llama3:70b" }
      }
    ]
  }
}

API Key Security

1. Use environment variables:

   export ANTHROPIC_API_KEY="sk-ant-..."
   export OPENROUTER_API_KEY="sk-or-..."
   

2. Never commit .env files to version control

3. Rotate keys regularly:

   npx agentic-flow router config update-key anthropic NEW_KEY
   

🚀 Getting Started Examples

Example 1: Use OpenRouter for Cost Savings

# Configure OpenRouter in .env
echo "OPENROUTER_API_KEY=sk-or-..." >> .env

# Use cheaper Claude model via OpenRouter
npx agentic-flow --provider openrouter \
  --model anthropic/claude-3-haiku \
  --agent coder \
  --task "Build simple CRUD API"

Example 2: Privacy-Sensitive Development

# Install Ollama
curl -fsSL https://ollama.ai/install.sh | sh

# Download local model
ollama pull llama3:70b

# Use local model
npx agentic-flow --provider ollama \
  --model llama3:70b \
  --agent coder \
  --task "Analyze confidential business data"

Example 3: Cost-Optimized Multi-Agent Workflow

# Configure cost optimization
npx agentic-flow router init --mode cost-optimized

# Run multi-agent task with automatic provider selection
npx agentic-flow \
  --router-mode cost-optimized \
  --task "Build full-stack app" \
  --max-cost 5.00
