Upscale rendered pictures aren't saving.

Resolution Issue
Thank you for bringing this up. It is understandable that this feels confusing, especially when the different quality settings can result in the same output dimensions.
 

With GPT Image 2 in Firefly, the "High" quality setting does not determine the image resolution. It is an OpenAI API parameter that affects the quality of the generation, including details, textures, and how closely the result follows the prompt.

Resolution is controlled separately, and that setting is not currently exposed as a user-controlled option in Firefly.
 

So, when you select "High," you are getting a higher-quality generation at the same output dimensions, rather than a larger image.

This distinction is also explained in OpenAI's Image Generation Documentation

The difference in credit cost for the High setting is related to the additional compute required for that higher quality level, rather than an increase in resolution.
 

That said, I agree that the current Firefly UI does not make this distinction particularly clear, which can understandably lead to the impression that "High" should mean a higher-resolution output. I appreciate you calling this out.

Cheers

Nate
