Route Every Request to the Best Model.
Stop overpaying for AI. Smart routers pick the right model for every request — optimizing for cost, quality, and latency automatically.
Save 40-70% on API costs. Automatic fallbacks. Load balancing. One integration, every model.

Why Model Routing Matters
Cost Savings
Route simple tasks to cheap models. Save expensive models for hard problems. Pay only for what you need.
Uptime
Automatic fallbacks across providers. If one model is down, requests route to the next best option instantly.
Unified Access
One API key, one integration. Access Claude, GPT, Gemini, Llama, Mistral, and hundreds more through a single endpoint.
How AI Starter Package Uses Model Routing
Our AI brain system routes every request to the right model tier automatically. No manual selection needed.
