Any model which is clearly the next major, canonical form of GPT will count for this market regardless of what it is called. I am assuming this will be called GPT-4.5 or GPT-5, but it still counts if it has another name. A larger context window does not count, a jump like GPT-3 to GPT-3.5 does count.

All options resolve NO as that month arrives, until when the next model is broadly released and all remaining options resolve YES.
