12.3M tokens in 27 minutes for $0.14: agent session with 99.6% cache hit
teortaxesTex · x · 2026-10-18
Developer teortaxesTex shared the usage stats of a long agent session: 12.3M tokens, 27 minutes, only $0.14. The core work was done in 20 minutes, after which the model kept re-rendering videos with narrow tweaks. The screenshot shows a 99.6% cache hit rate — 11.14M cached input tokens vs only 42K uncached input and 163K output — a vivid demonstration of how prompt caching slashes long agent session costs.
