LLM Inference Optimization

Anatomy of LLM Latency (TTFT, TPS, E2E)

Understanding LLM latency requires decomposing it into distinct phases. Each phase has different bottlenecks and optimization strategies. The three key metrics every FDE must know are TTFT (Time to First Token), TPS (Tokens Per Second), and E2E (End-to-End latency).
