A platform is offering a contest where participants can submit their predictions about whether OpenAI will publish a paper or webpage announcing the release of GPT-4, with criteria for resolution including showcasing examples of what it can do and offering some form of use to outside parties. The outcome depends on Scott Alexander's exclusive authority in his 2023 prediction contest. Another platform is focused solely on the event, without reference to any additional context or rules. A third option takes a more general stance, with no specific criteria for resolution.
