Minimax’s I2I “Subject Reference” model enables you to transform images while preserving the appearance of a subject using a single reference image. Ideal for maintaining character likeness—features, clothing, or expression—across different styles or settings.
About this model
Minimax's Subject Reference model transforms images while preserving the appearance and likeness of a key subject. Provide one reference image showing how your subject should look, then describe the new context or setting, and the model maintains subject identity while applying the transformation. Ideal for keeping character consistency, maintaining a face across style changes, or preserving object identity in new compositions.
Great for fashion designers showing consistent models across different outfits, character artists maintaining likeness through style shifts, or product photographers showing items in varied contexts. At just $0.01 per image, muapi makes this precision subject-consistency tool accessible for batch workflows and rapid iterations.
