FLUX 1 Fill Dev

FLUX 1 Fill Dev uses a source image, an edit mask and a text instruction to replace or retouch a chosen region while keeping the surrounding composition. Use it for product colorways, removing or replacing objects and localized scene repairs. In Flowctory, supply a square 1024 × 1024 source and matching PNG mask: white marks the editable area and black preserves it. The exposed workflow is 1K masked editing with twenty fixed steps, not canvas expansion, ACE++ identity workflows or arbitrary reference mixing. Review region boundaries and small details before final delivery.
