LATENCY & PERFORMANCEAI SRE

End-to-End AI Latency

End-to-end latency includes every stage from user request to final answer or completed action.

WHY IT MATTERS

Optimizing model inference alone does not help if retrieval, tool calls or output validation dominate total latency.

PRODUCTION EXAMPLE

Inference is 1.2s, but a slow ticketing tool adds 4s and a reranker adds another 1.5s.

SRE DECISION

Can traces show the percentage of total latency consumed by each stage?
