Recreating a specific image using seed may not be 100% safe.
The following two images were generated twice in different sessions, using the same size, prompt, seed.
{
"size": "1024x1024",
"prompts": [
"Japanese anime style. In a dimly lit dungeon, a fearsome beast with sharp claws and glowing blue eyes stands guard, ready to attack any intruder. "
],
"seeds": [3075182356]
}
Comparing them at the pixel level, will find they are slightly different. Perhaps the DALL-3 model will change over time (e.g. online learning).
Edit (2023/11/4):
There is no way to recreate the image using this approach.
