This market resolves yes if a model called GPT-6, or any variant thereof (gpt-6 sol, gpt-6 codex, gpt 6.1, etc) is released by OpenAI by September 15th 11:59 pm ET. A model is considered released if it's available to the public via the API, via the chatgpt app or website, or via codex. It resolves no otherwise.

I may trade on this market.
