Flux Dev

FLUX.1 [dev] is a 12B-parameter rectified flow transformer from Black Forest Labs that turns clear text prompts into high-quality images. Trained with guidance distillation, FLUX.1 [dev] delivers strong fidelity and efficiency comparable to state-of-the-art systems, while providing open weights for research and creative workflows. It supports diverse aesthetics and benefits from precise, specific prompts and iterative refinement. Intended under a non-commercial license, this system is well-suited for personal, educational, and scientific uses. Researchers can explore novel prompting and parameter tuning; artists can prototype styles, compositions, and concepts quickly. Outputs are available in PNG, JPG, or WEBP for flexible downstream use.
