Qual upscaler de imagens por IA é o melhor, e barato?

[Rocha Santos]

Which AI image upscaler is the best and cheapest? I would like to know if there is a free and cheap one that receives few rejections from Adobe Stock. I was currently using Adobe Firefly 3 to generate the images, now I am using Firefly 4, I used Picsart for 2x Upscaler, I changed to the Tiktok 4k Upscaler, but my rejections are on average 35% of the images I send, I would like to know tips to reduce this rejection further, I have a portfolio with approximately 400 images and I am already having frequent downloads. Can someone give me a tip, the dimensions of the images that Firefly delivers are 2688x1536px.

Different contributer using different softwares according to me Giga pixel is best upscaler...but totally depends on the your Ai generated images...any software just upscale does not manage or correct any rendering error

Thanks for the answer... the clarification helped me a lot

Upscale programs won't eliminate errors in the asset you are upscaling. They will amplify the errors. So, even if they do not introduce new artefacts, you still need to check your assets against errors.

Why are you assuming that rejections are due to the upscale software you're using? If your assets are being rejected on the basis of quality issues, you should know that there are many other quality issues that an upscaler doesn't fix.

I actually already had this suspicion that it could be the image itself, and not the upscaler issue. Thanks for the answer!

Firefly has issues with rendering, as all generative AI systems have:

A simple generation of colourful cubes gives this and other rendering errors, even that I expected more geometry errors. But there are also artefacts that would get amplified with upscaling, as the upscaling program rarely distinguishes between real graphic elements and artefacts.
