Seed Number

The Seed number functionality acts as a unique numerical identifier or starting point for image generation within the AI model. Think of it as a special code or number that establishes the initial conditions used by the AI to create an image. It is typically used to produce the same image output, ensuring consistency in results for reproducibility.

How to use the seed number

To access the Seed number functionality, click or tap the prompt box to reveal the options at the bottom and click the More icon located at the end of the prompt box option tabs to open a popup menu with the available choices.

If you dont enter any seed number in the field, the AI will use a random one and generate the image based on that seed number. You can enter any number to serve as a seed number in the corresponding field.

When you click on a particular image, its seed number can be found in the panel on the right (on PC) or below the image (on mobile devices).

The Seed Number that was used to generate the image.

The Seed number feature won’t produce the exact same image when changing the Render speed in Ideogram version 3.0, as it did in older models. However, the image will be similar if the same prompt is used.

Seed number use case

One use case would be to keep the same seed number and generate an image from the same prompt with different renderings. For example:

Seed: 406220 Rendering: Fast

Seed: 406220 Rendering: Default

Seed: 406220 Rendering: Quality

This feature can also be used to make small modifications to a prompt while keeping most of the image the same as before.

Prompt: ... The background is a dark blue gradient, ... Seed: 406220 Rendering: Default

Prompt: ... The background is a dark purple gradient, ... Seed: 406220 Rendering: Default

Prompt: ... The background is a dark red gradient, ... Seed: 406220 Rendering: Default

As you can see, the images are not identical, but they have the same composition and general appearance, with only the background modified as requested.

By using this technique and modifying the prompt—for example, by replacing the word "photography" with "painting" or changing the AI model—you’ll generate different images even when using the same seed number.
