In their own words
FLUX
FLUX is a set of AI models from Black Forest Labs for creating and editing images and video. FLUX 3 can make video with synchronized audio from text or images, or continue a clip, with a maximum length of 20 seconds. FLUX.2 generates and edits images up to 4 MP, with multi-reference editing, hex color control and text rendering. FLUX Tools add outpainting, object erasing, virtual try-on, video upscaling and deblurring. Access options include a browser playground, API and downloadable weights for self-hosting. Platforms listed are API, Linux, macOS, self-hosted, web and Windows. There is a free plan; the listed pay-as-you-go FLUX.2 [klein] 4B option is $0.01, paid once, with additional megapixel and reference-image charges. API use includes full commercial rights without a separate license; rights for open-weight models depend on their license. Submitted prompts, uploads, tasks and outputs may be used to train and improve models, with an email opt-out route.
