Resolves YES if within 1 month after the release GPT-5 there are options to choose different GPT-5 based models in the normal ChatGPT interface. Otherwise resolves NO. Previously existing models (4o, o3, 4.5, etc.) continuing to be available, or new models not based on GPT-5 (e.g. the upcoming open-weight phone-sized model) will not count. Tool options such as web browsing or the canvas feature will not count as a different model. "Thinking time" or similar options will also not count if the underlying model is the same.
