FLUX — Open-weights diffusion model family by Black Forest Labs with photorealistic outputs and strong text rendering. Open-weights diffusion model with publicly available model weights that can be downloaded and run locally.
About FLUX
FLUX is an open-weights diffusion model family from Black Forest Labs, whose founders were the original creators of Stable Diffusion.
It's notable for rendering legible text inside images — an area many models struggle with — and ships in variants: FLUX.1 [schnell] for fast generation, [dev] for non-commercial use, and [pro] via API, with downloadable weights you can run locally.
It fits people who want an open, modern model with strong in-image text, self-hosted or via API. Two caveats: the FLUX.1 [dev] weights are under a non-commercial license that restricts commercial self-hosted use, and the freemium web tier limits generations compared with paid API access.
It's the newer open-weights option next to Stable Diffusion, from the same lineage.
