A few days ago when I tried to generate an image it was noticeably different from the previous ones and said "Made with the old version of image generation. New version available now." under it. The article is from March so pretty old. Any time I tried to make a new picture it would say something like "This image was created with DALL·E, OpenAI’s legacy image-generation model. A newer model is rolling out soon."
I'm a free user, have I hit some kind of limit on the newer GPT-4o generator? I've been using it for months now without issue and even have access to it via Bing Image Generator. I don't see any other posts mentioning this so it doesn't seem to be a widespread issue? Any ideas?
