FLUX.1 [schnell] is a 12-billion parameter rectified flow transformer optimized for speed and efficiency. Trained using latent adversarial diffusion distillation, it can generate high-quality images in only 1 to 4 steps, matching the performance of closed-source alternatives. Released under the Apache 2.0 license, the model can be used for personal, scientific, and commercial purposes. For more details, visit the official Hugging Face page.
