Researchers are developing new methods to accelerate the inference process for diffusion models, which are computationally intensive for image generation. ChebBooster, a training-free framework, uses Chebyshev polynomial theory for stable and efficient acceleration, achieving significant speedups and FLOPs reduction on models like DiT-XL/2 and PixArt-$\Sigma$. Another approach, Orchestra, tackles inference on heterogeneous multi-GPU systems by employing spatio-temporal parallelism, intelligently allocating computational loads to mitigate straggler effects and reduce latency. Additionally, new theoretical frameworks are being explored, such as using SignReLU networks for ratio-based function approximation in diffusion models and developing efficient non-diagonal covariance modeling for improved sampling with Denoising Diffusion Probabilistic Models (DDPMs).
