MiniMax released FastH3 v1, an open-weight video generation model. In collaboration with FastVideo and Nuvalab, it utilizes FastGen to achieve up to 14x speedup on NVIDIA Blackwell GPUs. Demonstrations show it generating 15 seconds of 768p video in just 13 seconds. Fully open source, the project invites the community to run and improve acceleration recipes, marking the start of the open-weight video model era. Details on post-training improvements for speed and quality will follow.
