Minor changes to the name, such as using "o4-large-1125" instead of "o4", are acceptable when determining the announcement. Moreover, skipping some numbers (o5, o9) is similarly acceptable.

To count as announced, an official announcement, with information about the model's capabilities, must be made by OpenAI or an official partner of OpenAI. if it's banned in the US but releases in China this market would still resolve YES.

Note that the model being publicly available at a future date is not required. This market, had it been about o3, would have resolved YES "before January 2025".

  • Integrated GPT-5 scenario: If o4 is simply incorporated into GPT-5 (i.e. if o4 is not independently announced), the market resolves NO.

  • Independent or benchmark announcement: If o4 is trained independently or on top of GPT-5 and there is an official announcement (e.g. benchmark results) even if it is not released as a standalone model, the market resolves YES.

New market:

No pressure, don't have much of a stake personally, but a nudge, if you have forgotten about this

@JussiVilleHeiskanen might want to tag @Bayesian

thanks, I'll N/A, I think this was a pretty big oversight on my part

@Bayesian I think this is a fair decision, although I think you maaaybe could have waited until May 1st just in case they announced o4 full in the next few days. And by wait I mean wait to actually N/A the market, but just comment your decision now.

Why is this closed?

I closed the market to give myself time to determine whether o4-mini ought to count without having the traders trade on the deliberation. I have a final tomorrow so the market will unfortunately remain closed until at least then

@Bayesian April can resolve NO.

I assume an announcement of o4-mini by itself wouldn't count for this, right?

bought Ṁ10 YES

@TimothyJohnson5c16 Minor changes to the name, such as using "o4-large-1125" instead of "o4", are acceptable

@DavidHiggs I think "mini" is a different model though, not just a name change.

darn i missed this msg and that’s tricky and a pretty major ambiguity ig. Ive closed the market to deliberate

bought Ṁ50 NO

I think there will be no o4, and they're just going to integrate reasoning into GPT-5.

@TimothyJohnson5c16 fair, this market would resolve NO in that case. however if o4 is trained independently of gpt-5 or on top of gpt-5, in a way where they announce o4 benchmark results but say "btw it won't be relaseed independently, you can use it through gpt5", you agree that would count as openai announcing o4 right?

@Bayesian Sure, I guess that would count as "announced" even if it's not released.
