I've received messages from a few people saying that the whole "GPT-6.2 Betelgeuse" rumor was made up just to see how easily people would spread unverified leaks.
Basically, some "insiders" apparently posted about it knowing it was fake, deliberately misleading people as some kind of social experiment.
I absolutely hated that. And I'm now unfollowing some people over it, regardless of how much I trusted and supported them before.
