Can you explain what you mean by "stealth model"? What is it, who discovered it and how, etc?
This repo talks about it.
I wonder if the fact that the API may expect user tokens, but this doesn't provide them may be correlated with the bug people are experiencing with getting other peoples completions.
I hadn't heard about this, but I think I got one! I had a completion that really had me scratching my head.
Anyway I agree, if OpenAI is the kind of company to ban people, this is probably a good way to get banned.
