GPT-6 released by ...?
Market Rules
This set of markets predicts when OpenAI's GPT-6 model will be made available to the general public. Each of the markets below covers one possible deadline; any number of these markets may resolve to "Yes”. A market resolves to "Yes" if GPT-6 is launched and publicly accessible — including via open beta or open rolling waitlist signups — on or before the market's deadline. A closed beta or any form of private access will not suffice. The release must be clearly defined and publicly announced by OpenAI as being accessible to the general public.
GPT-6 refers to a product explicitly named GPT-6 (for example, ChatGPT-6o would count), or one that is recognized as a successor to GPT-5, similar to the progression from GPT-3 to GPT-4. Products labeled as GPT-5.5 or similar will not count for this market's resolution. In ambiguous edge cases (gradual rollout, regional restrictions, or completely different names that keep no connection to the standard OpenAI naming practices but are clearly presented as the successor to GPT-5), resolution follows the spirit of the question: has GPT-6 been made available to a meaningfully broad general audience by the deadline?
