Different configurations of the same app.

What are variants?

An app can have multiple variants optimized for different needs:

Choosing a variant

In the app runner, select before running:

1Variant: [quality ▼]2 3• default (8GB VRAM)4• fast (4GB VRAM)5• quality (16GB VRAM)  ◀6• cpu (no GPU)

Why variants matter

Speed vs quality trade-off:

• fast might take 5 seconds
• quality might take 30 seconds but look better

Resource requirements:

• Some variants need more GPU memory
• cpu variants work without a GPU

Private workers and variants

If using private workers, make sure your hardware matches the variant's requirements.

A quality variant needing 16GB VRAM won't run on an 8GB GPU.
