How to Set AI API Concurrency Limits? Four Criteria Plus Load Testing

Determining AI API concurrency limits requires balancing four constraints: account quotas, inference throughput collapse, output length, and p95 latency, all validated through load testing.

DeepInfra's TTFT/Throughput/E2E Framework: How Load Testing Reveals Performance Inflation in Self-Hosted AI APIs vs. Relay Stations

Learn to measure TTFT, throughput, and E2E latency to distinguish genuine self-hosted AI APIs from potentially inflated relay stations, with a reproducible load testing protocol and supplier acceptance checklist.
