Yeah, I heard about when ChatGPT removed I think it was O4? apparently there's an entire community devoted to "role playing" or rather dating a character powered by the model. GPT5 broke their entire relationship. Me and a few friends agreed it might have been worth spinning up a dating GPT O4 based service for those people to pay to migrate their AI 'companions' to. Azure still has these "abandoned" models.
On the other note, it also helps OpenAI because they don't have to manage setting up all that infrastructure just to let others use the model.
