Any time I feel like a LLM is getting off topic or has made multiple wrong turns, trying a new chat absolutely helps! Great video! I like your AI content!

Dude! I had no idea. I always had it summarize our conversation every so often, so that when it started to go bannanas, I could start a new chat with what we've done and our goals. It works decent.

I wish we could make a long-term memory for LLMS, that way they can store their knowledge outside of the memory and recall them later.

Yeah my adhd brain wants to talk about several things at once and then i noticed that it starts to get mixed up which is understandable that this was a good explanation. I'm very very new to ai and coding so this was a good video for me to watch thank you for sharing.

Watching this video after they added the branch, new chat feature solved a lot of this problem. Effectively being able to branch and pull earlier context as needed.
