## AI overview

This guide explains why latency is a key indicator of answer quality in AI applications. It covers latency across retrieval and serving pipelines, including vector embedding, indexing, reranking, LLM calls, and tools, and describes metrics such as TTFT, inter-token latency, end-to-end latency, and tail latency.

## Source excerpt

Your monitoring looks fine but your answers are getting worse. That pairing is common in AI apps, because retrieval and serving systems are usually built to degrade gracefully under load: search a cached subset instead of the full index, fall back to ...
