UnverifiedTurbo 4-step LoRA compresses the diffusion sampling process from the original tens of steps down to just 4 steps.78% similarUnverified4-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.75% similarUnverifiedLynnReal-Omni adopts four-step fast generation, significantly compressing inference costs compared to traditional diffusion models that require dozens of sampling steps.75% 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.69% similarUnverifiedCompared to full-context inference, AdaMem can reduce inference latency by up to 4×, and can match the answer quality of the uncompressed scheme while achieving latency as low as 1/4 of the full-context baseline.68% similar
