LLMs currently prefer to give you a wall of text in the hope that some of it is correct/answers your question, rather than giving a succinct, atomic, and correct answer. I'd prefer the latter personally.
Try o3. My (very limited) experience with it is that it is refreshingly free of the normal LLM flattery, hedging, and overexplaining. It figures out your answer and gives it to you straight.
Browsers just need to support <img src="foo.mp4" style="width:256px;"> already.
It should behave exactly like a GIF, loop by default, and be usable for emojis and everything.
There is absolutely ZERO reason we should be stuck to 256 colors for things like cat videos used as chat stickers. We have had 24-bit displays for ages.
