What is FLUX?

FLUX is a family of generative AI models from Black Forest Labs for creating images, video, and audio. Users can experiment in a browser playground, integrate models through an API, or deploy available open-weight models on their own infrastructure. Its image models support text-to-image and image-to-image generation, including varied visual styles, complex prompts, and text within images.

Video generation can start from text, an image, or keyframes and produce clips up to 20 seconds long, including multiple shots in one generation. Optional generated audio includes multilingual speech, sound effects, and ambience. The family also includes an action-prediction model that takes visual observations and text instructions to predict physical outcomes and robot control actions.

The hosted API uses pay-as-you-go pricing rather than subscriptions or seat fees, with image costs varying by model and resolution. Separate open-weight licensing options support self-hosting, fine-tuning, and LoRA customization, with different allowances for image volume, domains, and licensed users. Enterprise arrangements offer custom pricing, volume discounts, service-level guarantees, and dedicated support.
