Creative Upscale (async)
Takes images between 64x64 and 1 megapixel and upscales them all the way to 4K resolution. Put more generally, it can upscale images ~20-40x times while preserving, and often enhancing, quality. Creative Upscale works best on highly degraded images and is not for photos of 1mp or above as it performs heavy reimagining (controlled by creativity scale).

Body
The image you wish to upscale.

- Total pixel count must be between 4,096 and 1,048,576 pixels
What you wish to see in the output image. A strong, descriptive prompt that clearly defines elements, colors, and subjects will lead to better results.
To control the weight of a given word use the format (word:weight),
where word is the word you'd like to control the weight of and weight
is a value between 0 and 1. For example: The sky was a crisp (blue:0.3) and (green:0.8)
would convey a sky that was blue and green, but more green than blue.
1 - 10000A blurb of text describing what you do not wish to see in the output image. This is an advanced feature.
10000Dictates the content-type of the generated image.
jpeg, png, webp A specific value that is used to guide the 'randomness' of the generation. (Omit this parameter or pass 0 to use a random seed.)
0 <= x <= 4294967294Indicates how creative the model should be when upscaling an image. Higher values will result in more details being added to the image during upscaling.
0.1 <= x <= 0.5Guides the image model towards a particular style.
