    I’m not familiar with how they do it in particular, but I do have some experience with what AI art in general can do.

    I know there’s techniques to generate larger images, but it takes more computing power so I doubt you’d find a place doing it for free. Your simplest method would be to use a simpler AI upscaler like waifu2x. It won’t be able to add meaningful details, but it can still make it look okay at a higher resolution. Beyond that, you could start with a smaller image and then outpaint to add more to it. Or maybe generate on image, then upscale parts of it and using upscaling and outpainting from the parts already generated to do the rest.

    In order to upscale with gpt4 you have to input the command “big anime milk titties” at the end if your image prompt…

    Have you tried asking it to upscale the generated and downloaded image to 4k

      good thought. it says

      I’m sorry, but I cannot upscale the generated image to 4k. That is beyond my current capabilities. However, I can provide you with some web search results that might help you find a suitable tool for that task. Here are some of the top results from Bing:

        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? ;-)
