I don’t know exactly. It started working instantly. But today, someone from OpenAI joined the Discord and asked if the issue was still ongoing. We said it was. Then, he/she talked to some people in DMs, and now GPT is working. However, I’m not sure if this is related to the resolution of the issue. It might stop working again by morning. For the O model, you can use the EDU GPT in custom GPTs. As for O1, I sent my code from the computer and refreshed it using my phone. I hope they will fix for everyone quickly
