Black Forest Labs releases FLUX 3 Image: box-based editing touches not a single pixel outside the selected area
Prepared by Sintelligent with the help of SI. Publication time restored from the build log. . Updated: .
Image editing is becoming precise and repeatable, like working with code: both people and SI agents can now do it without destroying what is already finished.
According to Tech Times, the model accepts up to 10 reference images, outputs 4K (about 5456×3072) and lets users set the placement of elements with JSON boxes; when editing, only the specified area is redrawn and the rest stays numerically unchanged, so multi-step editing does not accumulate distortions, which matters for agents. The API and platform have been open since October 1; weights for self-hosting can be purchased by companies, and open weights are promised in the coming weeks. A 50% discount runs until October 8: $0.0205 per 768 px image.
