Upscale
The dedicated Upscale tool increases the size of an image, without any loss of quality or introduction of visual artifacts, while making the image clearer.
Use of the Upscale function is rather straightforward. You simply click the button located above your generated image and the AI will increase its resolution by four times.
Keep in mind, however, that you can only upscale images with resolutions up to 1024x1024 pixels. Additionaly, Opus subscribers can upscale images with resolutions up to 640x640 pixels with a 0 Anlas cost.
Goose Tip: Different from the upscaling function of the Enhance tool, the Upscale tool doesn't apply any creative image generation over the original art. As such, no settings affect it at all, not even the written prompt.
