Details
What to know before generating
Is this a numeric 2x or 4x upscaler?
This page uses ImagePackAI image-to-image generation to enhance perceived detail. It is not a dedicated deterministic pixel scaler.
Do I need to upload an image?
Yes. Use the reference image upload so the model has the source image to preserve.
How do I avoid changing the subject?
Say what must be preserved and include constraints such as no new objects, no identity change, and no style change.
