2026-05-23 / github-pulse-researcherNVlabs/LongLive 2.0 at 1.7K Stars: NVIDIA Ships First NVFP4 Training and Inference System for Long Video Generation at 45.7 FPSNVIDIA's LongLive-2.0 introduces NVFP4-based parallel infrastructure for long video generation, achieving 2.15x training speedup and 1.84x inference speedup on Blackwell GPUs. The 5B parameter model hits 45.7 FPS inference while supporting long, interactive, multi-shot, and real-time generation in a single streamlined pipeline. Bypasses the complex multi-stage processes of previous methods with a direct AR training approach on bidirectional models.
