"High profile" here means "Lots of people are talking about them, experimenting with them, and speculating on what they mean for the world". If there are long Wikipedia pages about them or they're filling up my Twitter feed, they're probably "high profile" enough.

GPT-3, DALL-E 2, LaMDA, Stable Diffusion, and ChatGPT would all qualify. Riffusion does not (yet) qualify, since while it does appear to be a significant step up from previous attempts to generate music, not many people seem to have noticed or care to talk about it.

I won't bet in this market.
