FLUX.1 [schnell] is a text-to-image model developed by Black Forest Labs with 12 billion parameters, based on a "rectified flow transformer" architecture. It was trained using latent adversarial diffusion distillation and generates high-quality images in just 1 to 4 Inference steps, making it significantly faster than the Dev and Pro variants. The model is openly available under the Apache-2.0 license and can be used for personal, scientific, and commercial purposes; weights are available on Hugging Face, with reference code on GitHub.
