Three state-of-the-art few-step image generation models, Latent Consistency Models (LCMs), Stable Diffusion XL Turbo (SDXL Turbo), and Stable Diffusion XL Lightning (SDXL Lightning), have been developed to accelerate image generation by reducing iterations from 50 to just 1-8 steps. These models use various techniques such as distillation and progressive distillation to balance speed and detail, with SDXL Lightning offering the best image quality among the three options, followed by SDXL Turbo, and LCMs providing a good combination of quality and efficiency for high-resolution image generation. The choice between these models depends on the primary concern of speed or image quality, with each model optimized for different use cases.
