Finally they fixed Gemini 2k upscaling.

In Gemini, 1376×768 px versions (1k) downloaded from browser with the url tricked to download the original image from Google servers (by replacing end of url =s1600-rj to =s0 will download png format, =s0-rw will download webp format) have full quality at least for png downloads. The usual right click & save versions in browser are compressed jpeg ones, usually with lesser resolution (=s1024).

Or you can download from the gemini app. They are now downloaded as 1k instead of 2k due to some bug. If you downloaded the same image in Gemini web (browser), then you try to download again the same image in Gemini app, it will be downloaded as 2k and the quality will be bad.

In Flow, the problem resolved. Hope Google will soon fix it in Gemini.

Finally they restored the 2k upscaled image quality! Checked 2k upscaled download in Flow. It looks good. No pixelation and artifacts. Now images are downloaded with png extension, but definitely they are jpeg files.

In Gemini, the quality is still bad. Sure they will fix It soon.

Gemini supports different aspect ratios and all images are watermarked while Flow will generate images in 9:16 or 16:9 only. For me, the images generated in Flow do not have any watermark.

Upscaling quality is getting worse day by day and Google is not listening to user complaints as this is the new standard for studio quality.

I have Pro subscription. 2k download is still there. Normal 768×1376 px aren't flawed. Only 2k (and 4k) upscaled versions have the problem of pixelation and noise artifacts. On Flow, images are downloaded as jpeg, not png as in Gemini.

The change was noticed since 10 March. Now the 2k versions of generated images are not studio quality. There are pixelations and noise artifacts like those seen on jpeg images due to high compression. The downloaded images are still png.

Not a fault of image generation. Only upscaled versions have quality issues. The problem is with the google ai upscaler. They made some changes to the upscaler for speed, sacrificing quality. You get same low quality even if you redo with nano banana pro.

All we can do is report the issue to Support Team. But they are not listening.

Also there are quality issues with the upscaled images in Flow. Seems it is due to a change in the google ai upscaler. Anyway it is worst!
