Early adopters were using gpt-2 and telling us it was amazing.
I used it and it was completely shit and put me off openai for a good four years.
gpt-3 was nearly not shit, and 3.5 the same just a bit faster.
It wasn't until gpt-4 came out that I noticed that this AI thing should now be called AI because it was doing things that I didn't think I'd see in decades.
I don't know what your operating definition of "grifter" is but for me, a grifter is not a company that delivers a product which gains a large adoption and mindshare (ChatGPT) and essentially sets the world on fire. (not an opinion on Altman specifically but OpenAI at large)
My definition is someone outright lying that gpt-2 was agi that should be regulated just so they could raise more money for the next round of training.
