Generation settings - WJI

Open the gear icon beside the prompt box.

Generation settings popover showing aspect ratio thumbnails, batch size slider, and weight sliders — The generation settings popover

Settings you will see most

Setting	What it does
Aspect ratio	A grid of ratio thumbnails. Only ratios the model supports appear
Batch size	How many results per run. The range comes from the model
Reference weight	How strongly references influence the result
Omni weight	On models that support it
Style weight	On models that support it
Stylize	Typically 0–1000, on Midjourney-family models
Style prompt	Opens the style picker
Duration	Video only

Auto match is a valid aspect ratio choice on some models — it matches the input image rather than forcing a shape.

Seed

When a model exposes a seed, it appears as a tag on the main form. -1 means unspecified, so the model picks its own. The seed is what makes a result repeatable. If you get an image that is nearly right, note its seed from the history card — clicking the seed tag copies it — and reuse it while you adjust the prompt.

Model-specific settings

Everything else in the popover is generated from the model definition and changes as you switch models. Each control has a tooltip explaining what it does. Common ones:

Resolution and output format
Chaos — variety, 0 to 100
Quality
Image weight and style reference weight on Midjourney-family models
Raw mode and HD

Batch size and storyboards

Choosing a storyboard layout forces batch size to 1, because the grid is the single output. See Storyboard mode.
