What is Flux AI?
Flux is an open-source AI image generation model family from Black Forest Labs (founded by Stable Diffusion creators) with Flux.1 Pro, Dev, and Schnell variants. Flux.1 Pro is considered by many as the best open model for photorealistic image generation, competitive with Midjourney V6. Flux Dev is available for local running; Flux Pro is available via API and integrated into many platforms.
How Flux AI works
Flux AI runs as diffusion models and generative ai software built around image and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, api, and local, with API access for teams that want to embed it into their own products.
