# Prompt Reuse metric

> Prompt Reuse in Analytics shows how much of its prompt an agent reuses, which lowers latency.

**Prompt Reuse** is a new metric in [Analytics](/collect-analytics) that shows the health of your agent's prompt. It measures how much of the prompt the AI model reused instead of reading it again.

Use it to understand why some agents respond faster than others: the more of its prompt an agent reuses, the lower its latency in the call.
