## Summary

NVIDIA and MIT's Efficient-Large-Model team released the Open-H3-Regenerate-2K model weights on Hugging Face, which regenerate low-resolution video drafts at 2560×1440 and up to 3840×2160 native 4K. On a single NVIDIA B200 GPU, the project's optimized pipeline cut processing time for a 5-second clip from 87.26 seconds to 22.45 seconds, about 3.9 times faster. On the RefinerBench-150 UniPercept perceptual quality benchmark, it scored 60.0 against 53.4 for the official H3-Regenerate-2K API.
