Sam Altman has suggested that "GPT-Next" may not be called GPT-5 at all.

A GPT-4.5 or any other model prior to "GPT-Next" won't count.

This market resolves based on the fifth major iteration.

If "GPT-5" includes multiple models, as long as at least one meets the YES criteria, it resolves to YES.

This market will resolve when "GPT-Next" from OpenAI is released and accessible via API. Even if the official name is known prior to release, it won't be resolved before.

A release here means "accessible to some users outside of OpenAI with no waitlist and no special criteria to be chosen" (e.g., general rollout).

Resolves as YES:

• The official model name (as in the API) contains the string "GPT-5" (case insensitive) explicitly. So, something like "GPT-5" or "GPT-5-Supernova" is YES.

Resolves as NO:

• The YES criteria are not met. So, something like "GPT-Supernova-5" or "Eucalypt" is NO.

• OpenAI doesn't release "GPT-Next" before 2026.

• OpenAI dissolves (rebranding with another name doesn't count).

OP Trading: Given the objective nature of this market’s resolution, I reserve the right to place bets. However, I will do so only after at least 5 trades or trade orders from different traders have been made, to avoid any unfair advantage.
