I think they all output that bold lettering, point by point style output. I strongly suspect it's part of a synthetic data pipeline all these AI companies have, and it improves performance. Claude seems to be the least of them, but it will start writing code at the drop of a hat. What annoys me in Gemini is that it has a really strange tendency to come up with weird analogies, especially in Pro mode. You'll be asking it about something like red black trees and it'll say "Red Black Trees (The F1 of Tree Data Structures)".

Yes, the analogy habit is the most annoying of all. Overall formatting for me is doable, if it didn't divide up an answer into these silly arbitrary categories with useless analogies. I've tried adding in my user preferences to never use analogies but it inevitably falls back into that habit.
