    Bing itself cannot upscale it or generate a higher resolution, it just can’t. Vast majority of ai generators can’t, by the way.

    You can either Upscale it yourself using something like upscayl (https://www.upscayl.org/) which is probably the easiest option, although not very customizable. Or learn to use something like comfyui (https://comfyanonymous.github.io/ComfyUI_examples/upscale_models/) for more control. And you can even generate images with comfyui if you want.

    You can also try the online option by using something like nightcafe (https://creator.nightcafe.studio/studio). Upload your image, select upscale and generate. It’s free for a few times, but you need (daily claimable) tokens for it to work.

    Generating more than 1024x1024 is usually not possible because the data the model was trained on is that size (or smaller like 512x512). Try to generate any higher and you’ll get very weird and ugly results.

      Stable Diffusion in particular has this issue with limbs. People have 2 arms at 512x512? Surely they must have 4 arms at 1024x1024! That’s just math.

        Yeah, It’s the wrong way to do it and will lead to unusable results. The correct way to do it is to generate an image with the resolution the AI was trained on an then upscale it.

        (And 1024x1024 is four times 512x512 so they should have eight? ;-)
