Multi-Model Features

Intelligent routing and unified access

🔀
Smart Routing
Automatically route requests to the best model based on task type, cost, and availability.
🔄
Auto Fallback
Seamlessly fall back to alternative models when primary is unavailable or rate-limited.
📊
Cost Optimization
Route to cheaper models for simple tasks, premium models for complex ones.
🔌
Unified API
Same request/response format across all models. No provider-specific code changes.
⚖️
Load Balancing
Distribute requests across models and providers for optimal performance.
🎯
Model Selection
Let the gateway choose or specify exact model per request with override options.

Unified API Example

Same code, different models

🔄 Multi-Model Request JavaScript 
// Same API for all models
const response = await fetch('https://gateway.example.com/v1/chat', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    // Option 1: Let gateway choose
    model: 'auto',
    
    // Option 2: Specify model
    // model: 'gpt-4',
    // model: 'claude-3-opus',
    // model: 'gemini-pro',
    
    messages: [
      { role: 'user', content: 'Hello!' }
    ]
  })
});

const data = await response.json();
console.log(data.model);  // Shows which model was used
console.log(data.content); // Response content
