Unverified50% confidenceFactExact time
The four-step acceleration scheme trains a model version capable of completing generation within 4 steps through distillation technology; compared to the standard sampling process of approximately 50 steps, the speed is greatly increased but the image quality loss is more noticeable than with quantization.

Unverified4-step sampling is a strategy that trades quality for speed and may involve compromises in detail and temporal consistency compared to full multi-step sampling.78% similarUnverifiedWhen the number of steps drops sharply to 4, the denoising span required per step increases significantly, forcing the model to make bolder predictions in a single step, which can easily lead to loss of high-frequency detail and incoherent motion trajectories.76% similarVerifiedOn convergent tasks, there is a clear performance saturation phenomenon after models reach a certain scale, where continued increases in parameter count or training data yield rapidly diminishing marginal contributions to accuracy.73% similarUnverifiedLynnReal-Omni adopts four-step fast generation, significantly compressing inference costs compared to traditional diffusion models that require dozens of sampling steps.73% similarUnverified扩散模型步数越多理论上结果越精细，但耗时也成比例增长，20步是速度与质量的经典平衡点72% similar
