The real news for me is GPT 4.5 being deprecated and the creativity is being brought to "future models" and not 4.1. 4.5 was okay in many ways but it was absolutely a genius in production for creative writing. 4o writes like a skilled human, but 4.5 can actually write a 10 minute scene that gives me goosebumps. I think it's the context window that allows for it to actually build up scenes to hammer it down much later.
Cool to hear that you got something out of it, but for most users 4.5 might have just felt less capable on their solution-oriented questions. I guess this why they are deprecating it.
It is just such a big failure of OpenAI not to include smart routing on each question and hide the complexity of choosing a model from users.
