Researchers have developed MobileWan, a 5-billion parameter video diffusion model that can run on mobile devices. This is achieved through a recurrent reformulation and structured compression technique, which allows a large server-scale model to operate efficiently on memory-constrained hardware. MobileWan uses a recurrence distillation framework and causal linear attention to process video generation in a chunk-wise autoregressive manner, maintaining temporal coherence. The model also incorporates attention head pruning and memory-optimized decoding, enabling it to generate 5-second videos at 480x832 resolution in approximately 20 seconds, setting a new state-of-the-art for mobile video generation with a VBench score of 83.79.
