"cache miss": OpenAI and Gemini with the changing clock text at the START of the system prompt; Anthropic with caching off.
|
|
"cache hit": the clock text moved into the user message, so the system prompt never changes; Anthropic with SYSTEM_ONLY.
|
|
The Anthropic "clock inside the block" row keeps the clock at the END of the one cached system block: it changes every request, so every request pays the cache write.
