What is a seed

A seed is the number that randomness starts from. Think of it as a variant number: the same seed with the same prompt and settings gives the same result.

1. A number field. Empty means a new result each run; enter a number and the result repeats.

Why it matters

• Reproduce a good result. Like an image? Save its seed and you can get it again.
• Iterate precisely. Fix the seed and change only the prompt — you'll see exactly how your edit affects the result, no lottery.
• Fair comparisons. Same seed = same randomness, so comparing models and settings becomes meaningful.

How to use it

Leave the field empty for a fresh variant every run. Found a great frame? Copy its seed from the generation history and paste it into the field.
