Do more persona files increase LLM request expenses?

Thanks a lot. Does anyone have a good experience on which values to use on those? I have no idea.

A PDF with 30 pages would have around 7500 words, maybe. That might be extrapolated to 20000 tokens.

Assuming that, would would it mean if I set Upload chunk tokens with value 2000, for example? Will it “read and take into account only 10% of the PDF” when building a response?
