IFM 展示 PAN 2 世界模型演示:模拟墨水滴入水中扩散

Why we picked it

IFM 放出了 PAN 2 的演示视频,内容是墨水滴进试管的扩散过程,你可以自己看看有没有穿帮。跟 Sora 这类视频模型比,它更强调物理规律。做仿真或机器人训练的可以看看。

IFM 发布了 PAN 2 世界模型的演示视频,模拟场景是把墨水滴入装有水的试管。模型生成的水体流动、墨水扩散过程符合物理直觉,观看者难以察觉明显破绽。这类演示测试的是模型对真实物理规律的掌握程度,而不仅是画面美观度。视频由 IFM 官方渠道发布,展示了 PAN 2 在流体模拟上的表现。

墨水扩散是全球观众见过无数次的现象,任何异常都会立刻被大脑识别,因此它是检验世界模型的常见压力测试。PAN 2 能在无明显穿帮的情况下生成扩散过程,说明其对流体运动的建模达到可用水平。

世界模型方向上,PAN 2 将与 Sora、Genie 等产品在物理一致性上竞争,机器人训练与仿真团队是这类技术的主要潜在用户。

This is a demo video from IFM's PAN 2:

Someone adds ink to a test tube of water.

Our brains know what this should look like. We've seen it before a million times.

Look at this video and tell me if anything looks off to you. https://t.co/RwokT39GPT
