There was a notice for a while recently (just cleared when I checked again) about general API / service problems at OpenAI. Maybe that was the problem?
Its working for me (a little bit slower than last time I used it, and doing two instead of the four images on a request that it had done previously, and both with the same expanded (compared to the request) prompt, instead of each being a different prompt expansion, so I suspect recent usage levels may have resulted in some changes to the ChatGPT image generation configuration).
