Gemini 3.7 Flash has caching issues

So the 207.9K context did not “turn into” 855K input. The 207.9K is the approximate size of one late-stage prompt, while 855K is the sum of the uncached portions from 123 prompts.

However, if there were no long pauses or the beginning of the prompt was not rewrited, then the input (or cache write) should match the final size of the session window (if no context summarization occurred).
