I don't get the hype. Tested it with the same prompts I used with Midjourney, and the results are worse than in Midjourney a year ago. What am I missing?
The hype is about image editing, not pure text-to-image. Upload an input image, say what you want changed, get the output. That's the idea. Much better preservation of characters and objects.
Great question. I really doubt it would be able to support any resolution. I'm sure that behind the scenes it scales it down to somewhere around 1 mp before processing even if they decide to upscale and return it back at the original resolution.
