Understanding the seed and reproducibility
The seed is the starting number the model uses to generate an image. It sits behind every render and decides how much a result stays the same or changes between generations.
1. What a seed does
The same prompt combined with the same seed produces the same image every time, on the same settings. Change the seed and you get a different image from the identical prompt, since the model starts from a different point.
2. Random by default
By default, tendre.AI picks a new random seed on every generation, which is why pressing Generate repeatedly with the same prompt gives you a fresh variation each time.
3. Lock a seed to refine
When a result is close to what you want, lock its seed in the generation panel. With the seed fixed, you can adjust the prompt (lighting, outfit, a small detail) and see the effect of that change alone, instead of a completely new image.
4. Reproduce an image exactly
To recreate a past result, use the same prompt, the same seed and the same generation settings (size, style). This is useful for comparing style presets or settings side by side on one fixed composition.
Combine seed locking with a batch to compare several unlocked variations before settling on one to refine. See also the Prompting guide.
