Why would there be thousands of them? Wasn't the last GPT where the research actually was shared, GPT3? Hard to imagine that OpenAI suddenly will start releasing models more often than what they have been doing so far.

Edit: That's what I get for reading the comments before the article... "GPTs" is actually a new thing they introduced, where you can create your own "GPT" somehow, not just pluralization of GPT as we've know it.

That's some really messed up naming if anything. But regardless, parents comment makes a lot more sense now.
