FLUX 3
FLUX 3 is Black Forest Labs' flagship image model: one model that generates from text, edits photos and composes new scenes from up to ten reference images. Before it draws, it can research your prompt with web and image search, so real places, products and events come out right. Exact typography, element-level layout control and output up to 4K (16 MP) make it a natural fit for print-ready posters, apparel graphics and ad creatives.
