DeepMind Genie 4 体验：画面逼真但可控性差
有人上手试了 Genie 4，画面是真逼真，想让啥出现就有啥，但操控角色基本不听使唤，转个身车还会变形，看完你对它的真实水平有数。
一位用户实测了 DeepMind 的 Genie 4 交互式世界模型。他评价其画面非常逼真、质量高，用提示词就能让物体在场景中即时出现。但实际操控体验不佳：猴子、汽车和双翼机都难以按意图转向，物体还会出现时间一致性问题——例如一辆 Mustang 轿车在他转身后改变了朝向，驶离时还变成了一辆出租车。
Genie 4 is pretty impressive. I find the visuals to be very realistic and high-quality. The ability to prompt anything into the world and have it just appear opens up all sorts of possibilities to steer a scene in whatever direction you want.
I found it really difficult to control the object on the screen, the monkey, the car, and the bi-plane all sort of ignored my attempts to steer them. There was also some temporal coherence issues where I'd turn around and face a different direction and then return to my original position and things would have changed. The Mustang, for instance, changed directions when I turned around. When it drove off later in the scene, it turned into a taxi... Little things like that change over time.
Visually, however, it's really impressive. (IMO)
