Fill Generative Seed

Used to create predictable outputs when using fit=fill&fill=gen. The fill-gen-seed parameter accepts an integer that sets a seed for generative fill. Once a generative output is used with a seed for the first time, you can use that seed value to generate similar results with different prompts.

For example, if we generate the first render for fill-gen-seed=3 with the prompt eagle flying around, we will get this image below.

Any change to the prompt will always yield a similar image as long as fill-gen-seed=3 is used, even if we change the prompt to something like dragons flying around. https://assets.imgix.net/example-images/generative-fill/man-standing-on-cliff.jpg?fill=gen&fill-gen-pos=left&fill-gen-prompt=dragons%20flying%20around&fit=fill&w=600&h=900&auto=compress,format&fill-gen-seed=3&auto=compress,format

Since we're using the same seed as the first generative fill ever returned, the positioning of the objects and shape will generally remain the same.

If we use a new seed (fill-gen-seed=4) and we have never used that parameter value before, the output will be very different: https://assets.imgix.net/example-images/generative-fill/man-standing-on-cliff.jpg?fill=gen&fill-gen-pos=left&fill-gen-prompt=dragons%20flying%20around&fit=fill&w=600&h=900&auto=compress,format&fill-gen-seed=4&auto=compress,format

Any variation of fit=fill&fill=gen with fill-gen-seed=4 will return similar results to the first image ever output with fill-gen-seed=4.

It is not possible to clear a seed value once it has been used. We recommend incrementing your seed value to generate new generative fill variations.
