I have two nearly identical chatbot A and B (A's summary agent set to 100 tokens and B's summary agent set to 200 tokens.) When I asked the exact same question and search from kb, I found that B's answer is always longer than that of A. It is the first question after user name input so suppose there is no detailed summary. Number of messages in "Extract from history" is set to 0 as well. What kind of factors are causing the difference? P.S. the reason is very important for the product and hopes someone can answer it. Thank you.
