Oh hey... leep an eye on your CPU load. The problem might be on the near end. In my case on a slower machine it slows down if you're dealing with a very long chat.
I think that's not the issue here but I do notice the browser going crazy after a while of chatting with ChatGPT. The tab seems to consume a baseline CPU while doing nothing. I just brush it off and close it... bad JavaScript maybe. I should look into this and report as a bug, thanks for the advice.
(DO report this as a bug if so)
