AI agent cache failures explained: GPT, Claude, and gateway issues

By PulseAugur Editorial · [1 sources] ·

This article explains why AI agent cache hit rates can unexpectedly decrease, even when the underlying models like GPT and Claude support prompt caching. It details how opaque third-party gateways can obscure cache usage and lead to low hit rates by altering prompts with dynamic data, tool schema changes, or load balancer shifts. The piece emphasizes the importance of auditable gateways that provide clear evidence of cache usage, including metrics for both eligible traffic and overall input reuse, to ensure reliable performance for cache-sensitive applications.
