Minor changes to the name, such as 'GPT 5.5 Turbo', or other names for a model generally expected to be called GPT 5.5, will count for the purpose of this market.

The model must be accessible without individual vetting or invitation — free or paid, via API or product. Open, non-selective waitlists count. Closed betas, invite-only access, researcher programs, A/B tests, and anonymous benchmark appearances do not. Country-level bans do not prevent resolution.

Time to resolve?

Why are all the probabilities on the ceiling, did anyone say it's released?

@NayutaIto it’s releasing tomorrow probably

@Bayesian what

@NayutaIto what what

@Bayesian I think I missed the news...

@NayutaIto @Bayesian

bought Ṁ20 YES

if OpenAI skip 5.5 and go to 5.6 or 6, for example, you’ve said this would not count, so would these all resolve NA or all no?

bought Ṁ1 NO

@nostream no I guess

Would GPT 6 count?

@badd no

5.5 codex count?

@7028 yea

OpenAI said that the next model they will release is GPT 5.3. Though I agree that the market should not resolve yes.

Would 5.3 count? Doesn't look like there is a similar market for potential releases between 5.2 and 5.5.

@moozooh no
