About

Model routing is a critical infrastructure pattern for modern AI applications. It encompasses intelligent request routing across multiple LLM providers, cost-optimized model selection, load balancing for inference workloads, and unified API gateways that abstract away provider complexity.

This list covers the full spectrum: from smart routers that choose the optimal model per request, to high-performance inference engines, to unified gateways that provide a single endpoint for 100+ LLM APIs.

Criteria: Repositories with 1,000+ stars, actively maintained, related to model routing. Last updated: 2026-11-04
