DeepMind 发布 Genie 4 世界模型，提升物理与人物模拟真实度
DeepMind unveils Genie 4 world model promising more realistic physics and humans
Google DeepMind 发布 Genie 4 世界模型，称其在几乎各方面都优于 Genie 3，模拟的物理效果和人物更真实，并新增音频。该模型无需预先渲染环境或编写交互元素，用户描述需求后即可实时逐帧生成可探索的虚拟世界；DeepMind 认为世界模型是通往 AGI 的关键，可用于为实体机器人构建训练环境或加速创意原型设计。

Last year, Google DeepMind sent gaming stocks tumbling with the reveal of its Genie 3 world model. Since then, world models have become a major focus of AI labs around the world, but Google isn't resting on its laurels. Researchers have been hard at work on an updated model that improves on Genie 3 in almost every way. And if you pay Google enough money, you might actually get to use Genie 4 before too long.
It's easy to look at the output of Genie 4 and see a video game, which is why Genie 3 caused so much consternation in the gaming industry. DeepMind doesn't think about it that way, though. According to Google, world models are a key element in the march toward artificial general intelligence (AGI). A world model creates a virtual world, but it doesn't require pre-rendering environments or programming interactive elements. You simply tell the model what you want, and it generates the experience frame by frame in real time as you explore it.
DeepMind says this technology could create infinite training environments for physical robots or unlock new avenues of rapid prototyping for creative fields. Of course, that requires the model to accurately simulate what you want. Genie 4 has several improvements that make its simulations more useful, and that's thanks in part to Google's updated Gemini models.
