Hii, ACC doesn't use a fixed message count to start summarization. Instead, it estimates how long the whole prompt is (which includes the chat), and summarization happens if it exceeds a fixed number of tokens (currently 5200). On average, I think that should be somewhere around 3,750 to 3,900 words, if memory serves right.

An aside for anyone interested: using message count to kick summarization is something I experimented with on my fork, but that has it's own problems as well, as a lot of the time summarization triggers without the conversation having all that much "information density". I assume that's why this was never implemented, though I could be wrong. Anyway, what I had to wind up doing is make the messagesBeforeSummary slightly bigger based on the number of summaries, which isn't perfect obviously, but made it more-or-less workable.

For hours? Stupid question: did you enable the long-term memory? just asking bc I forget that sometimes... and "hours" of writing is quite a long time.
