NVIDIA team builds on MiniMax H3 open-source video enhancement solution, supporting up to 4K regeneration

Zhitong Finance APP has learned that recently, the Efficient-Large-Model team, composed of researchers from NVIDIA and MIT, released the model weights of the video enhancement project Open-H3-Regenerate-2K on Hugging Face, with the accompanying inference code already open-sourced in the NVlabs/Sana repository. The solution is based on MiniMax H3 and regenerates low-resolution video drafts into high-resolution videos, supporting 25601440 2K output and enabling native 4K regeneration at up to 38402160.
