Resolves YES if OpenAI releases GPT-5 during the OpenAI San Fransisco, London or Singapore DevDays, or announces it and releases it in the following 2 days (to avoid resolving NO in the case of technical difficulties).
For the purpose of this market, GPT-5 is whatever new major flagship model is next released, that is a GPT or has similar capabilities to a GPT, and is not part of the GPT-4 family (including GPT-4.5). If a smaller version of the "main" GPT-5 model is announced, like Google did when releasing Gemini Pro before Gemini Ultra, this counts as releasing GPT-5. If they announce a release in the coming 2 days, but first announce this release during DevDay, this market still resolves YES.

"announces its release in the following 2 days" -> did you mean "announces it and then releases it in the following 2 days" or "announces in the following 2 days that it will be released anytime"? From the parenthetical and the discord convo I assume the former but as written it sounds like the latter
