Researchers have developed CARV, a new framework designed to reduce the variance in gradients used by diffusion models in various downstream applications. This method amortizes expensive upstream computations by reusing them across multiple diffusion noise resamples, leading to significant compute multipliers. CARV has shown to improve efficiency in text-to-3D generation and data attribution tasks, though its impact on single-step distillation was limited when gradient variance was no longer the primary bottleneck.
