Lovable details its LLM provider load balancer that preserves prompt caching at scale.
Lovable's infrastructure team describes how it routes traffic across multiple LLM providers at over one billion tokens per minute, using multiple fallback chains with project-level affinity to preserve prompt caching and automatically adjusting provider weights via a PID controller to handle outages and rate limits.
From the source
To preserve prompt caching while still handling failures, we don't rely on a single global fallback chain. Instead, we generate multiple fallback chains with different providers as the first choice. Each project is assigned one of these chains and keeps it for a short window of time, so that consecutive requests for the project are routed consistently.
