Long video generation is a systems problem.
Introducing LongLive-2.0 from NVIDIA Research: an end-to-end NVFP4 training and inference system for long video generation.
Low-precision deployment often relies on post-training quantization, creating a gap between how models are trained and how they run.
LongLive-2.0 aligns NVFP4-aware training, distillation, and W4A4 inference, maintaining strong benchmark quality while improving speed and memory efficiency.
