Leak Source:

Contrary to making the resolution of this prediction happen on the exact date of the 'leak', to make it harder, the resolution will be 'YES' when such an event takes place before May 15 and will be 'NO' if nothing comes to fruition before May 15.

Constraint: The event has to be of a similar standard to how they conducted Dev Day, or in other words, it can be a public (edit: or even private this time) setting where an audience listens to OpenAI release or announce something.

EDIT (May 11th, 2024): Just to elaborate, they need to have a physical audience, similar to how Dev Day was conducted. It can even consist solely of employees as the primary audience in their headquarters or any place, but livestream viewers don't count as part of the audience. So, there may be a traditional stage or not, where they will demonstrate what they're showcasing to the audience, which can be livestreamed or not.
