LATENCY & PERFORMANCEAI SRE

Context Length as a Reliability Variable

Longer contexts increase compute and memory pressure and can reduce the number of concurrent requests a serving stack can support.

WHY IT MATTERS

A product change that increases context may create an infrastructure incident without changing request count.

PRODUCTION EXAMPLE

A new conversation-memory feature doubles average prompt length and suddenly pushes KV cache utilization above 90%.

SRE DECISION

Are context-size distributions part of performance and capacity reviews?
