FLUX Outpainting

FLUX Outpainting is a dedicated image expansion model from Black Forest Labs that extends an existing image beyond its original borders in a single call. It is tuned to continue scene content, lighting, texture, and composition naturally without requiring a text prompt, making it useful for aspect-ratio changes, social reformats, banner layouts, and other canvas-extension workflows.
