Which comment claimed that LLMs were marketed as super-intelligence? I'm looking up the chain and I can't see it.

I don't think they were, but I think it's pretty clear they were marketed as being the imminent path to super-intelligence, or something like it. OpenAI were saying GPT-(n-1) is as intelligent as a high school student, GPT-(n) is a university student, GPT-(n+1) will be.. something.

That's the whole discussion here: "It's mostly because of how they were initially marketed. In an effort to drive hype 'we' were promised the world. Remember the "leaks" from Google about an engineer trying to get the word out that they had created a sentient intelligence?"
