视频生成速度从分钟级降到秒级，做 AI 视频创作和实时交互的团队可以直接用开源方案，大幅降低硬件门槛。
Hao AI Lab 开源了 FastVideo Dreamverse 项目，将视频生成速度大幅提升。此前在 8 张 Blackwell GPU 上生成 5 秒视频需约 25 秒，现在单张 Blackwell GPU 仅需 4.2 秒。该技术基于 LTX-2 模型，可在单张 NVIDIA B200 GPU 上 7 秒生成 30 秒 1080p 视频。项目已完全开源，包含代码和博客说明。

You should read this thread. It used to take about 25 seconds to generate a 5-second video on 8 Blackwell GPUs. The legends at @haoailab brought that down to just 4.2 seconds on a single Blackwell GPU… and then open sourced the tech behind it.
