Researchers have developed Flash-VAED, a framework designed to accelerate the VAE decoders used in latent diffusion models for video generation. This approach employs channel pruning and dominant operator optimization to reduce inference costs, achieving approximately a 6x speedup in VAE decoding while retaining up to 96.9% of reconstruction performance. When integrated into end-to-end generation pipelines, Flash-VAED can accelerate the process by up to 36% with minimal impact on quality, as demonstrated on benchmarks like VBench 2.0. AI
