Agent Context Bottleneck: 99.9% Cache Hit Rate Masks Inefficiency
teortaxesTex · x · 2026-08-11
Addressing the 99.9% cache hit rate in long-context agents, a developer pointed out that this doesn't necessarily mean efficient input processing. Instead, it often indicates the model is struggling back and forth in an oversized context window, or that sequential tool calls are blowing up agent turns, resulting in an inability to move forward. This highlights the need for deeper model-harness co-optimization.
