We will consider OpenAI banned or effectively banned if a country on the list of supported countries at the time of question launch (link to archived list) is removed from that list due to new regulatory or legislative action taken by that country. Reputable news media reports and/or official announcements by OpenAI or the country’s government will be used to determine the reason OpenAI stopped supporting access. A ban would apply to any of OpenAI's current or future Generative Pre-trained Transformer (GPT) models, including ChatGPT, GPT3.5, GPT4, through either a web-hosted user interface or API.

If regulators ban ChatGPT specifically, but not broader API access, this question will still resolve "Yes".  Likewise if API's are banned, but not user interface components (e.g. ChatGPT), this question will resolve "Yes". Bans or regulations enacted by supranational organizations (e.g., the European Union) that are binding on its member countries would count towards resolution. OpenAI blocking access for other reasons (e.g., its initial ban on Ukraine due to sanctions on Russian-held Crimea) would not count. Temporary bans will count.

Note that the list of supported countries at the time of question launch includes Italy, so new regulatory activity by the Italian government that prompts OpenAI to stop supporting access in Italy would count.
