AI 视频能做到“边播边打字、实时改写世界”了？ 以往大家看 AI 视频，都是输完提示词等两分钟生成一段固定片子。看到 PixVerse @PixVerse 最新发布的 R2世界模型十分有意思！ 我用40秒的视频Demo演示一下： • 在同一片大雾里，你在下方打字输入小女孩，雾中就会走出一对母女； • 但如果你改输入 Dragon，同一片迷雾中就会直接生成一只巨龙！ 不需要重新排队渲染，甚至在视频播放推进的当下，场景和实体就会随着你的指令实时分叉 大家肯定会好奇：想要“实时”，模型就必须做小、做快；但想要“懂复杂现实”，模型又必须足够大。这俩怎么可能兼顾？ 我看了一下 PixVerse R2 的技术文档，按照官方的技术说法，他们其实是把“能力”与“效率”彻底解耦了： 底层专门用因果自回归架构，配合多时间尺度记忆把全局光影和物理逻辑锁住，保证长程推演画面不崩；而在推理端，通过 90% 以上的块稀疏计算砍掉多余算力，才把延迟硬生生压到了可实时交互的临界点.....真是个好东西啊
