I was getting very high quality, optically realistic images with varying tones and natural lighting. Now the images come out super grainy, sterile and low quality no matter how much I try to force the prompts. Is this issue occurring for anyone else? Is this a backend tuning issue?
Welcome to the forum!
Can you be more specific?
Show prior positive results with current degraded results along with the prompts and configuration used, such as which model, settings, etc.
I recommend you to check this topic:Collection of GPT-image-generator 2.0 issues, bugs, and work-around tips (check first post)
There are others that are experiencing the same kind of issues and maybe share tips for a workaround, if someone discovers some.
