01
Route
Smart & Speedy LLM Routing
We make sure you always have the best model for your request, so you can focus on shipping features.
Start routing smartly Learn more
What is LLM routing?
LLM routing intelligently directs your requests to the optimal model based on your criteria - whether that's cost, speed, accuracy, or availability.
Instead of managing separate integrations for OpenAI, Anthropic, Google, and dozens of other providers, you route through one unified interface that automatically picks the best option.
With smart load balancing, automatic failovers, and response caching, routing ensures your app stays fast and reliable while optimizing costs across all providers.
02
