FLUX 3 Image

The image model in Black Forest Labs' FLUX 3 family, launched 1 October, following FLUX 3 (week 30) and FLUX 3 Action (week 40). It is built for precise control: elements are placed with JSON bounding boxes on a 0 to 1000 grid, up to ten reference images can be combined into one layout, and multi-step edits recolour, replace or move single elements while leaving other pixels unchanged. It renders natively at 2K and 4K, up to 5456x3072 (about 16.8 megapixels), with no separate upscaling step. Available through the BFL API and a web playground, with non-commercial and commercial weight licences listed for self-hosting; coverage disagrees on when public open weights arrive. No benchmark numbers on the page.
