Researchers have developed LongLive-2.0, a parallel infrastructure designed to optimize the training and inference of long video generation models. This system utilizes NVFP4 precision and sequence-parallel autoregressive training to reduce memory requirements and accelerate computations. For inference, LongLive-2.0 employs techniques like W4A4 NVFP4 inference and asynchronous streaming VAE decoding to achieve high throughput, demonstrating up to a 2.15x speedup in training and 1.84x in inference.
