FLUX

FLUX is a set of AI models from Black Forest Labs for generating and editing images and video. FLUX 3 creates video with synchronized audio from text or images, and can continue an existing clip; videos can be up to 20 seconds. FLUX.2 generates and edits images up to 4 MP, with multi-reference editing, hex color controls, and text rendering. Additional FLUX Tools cover outpainting, object erasing, virtual try-on, video upscaling, and deblurring. Access is available through a browser playground, an API, or downloadable open weights for deployment on customer infrastructure. The listed platforms are API, Linux, macOS, self-hosted, web, and Windows. FLUX has a free plan, with paid options including pay-as-you-go FLUX.2 [klein] 4B at 0.01 USD per once; additional megapixels and reference images are billed separately. API use includes full commercial rights without a separate license, while open-weight commercial rights depend on the model license. Submitted prompts, uploads, tasks, and outputs may be used to train and improve models; the privacy policy provides an email opt-out route.
