Video Delta Net speeds up Minimax-H3 video generation 75-90x, faster than playback
xiuyu_l · x · 2026-09-03
Open-source video generation gets a speed breakthrough: Video Delta Net (VDN) uses hybrid attention for near-lossless live text-to-video, accelerating Minimax-H3 by 75–90x — generating 14 seconds of 768p video in just 11 seconds on 8× NVIDIA B200 GPUs, faster than playback speed with negligible quality loss.
The researchers (working with Haocheng Xi of UC Berkeley and team) argue video generation has long faced a speed–quality trade-off, and VDN shows you don't have to choose. Checkpoints, training/inference code, and a technical blog have been released.
