DeepMind 发布 Genie 4 世界模型，宣称物理与人物模拟更真实
DeepMind unveils Genie 4 world model promising more realistic physics and humans
DeepMind 公布新一代世界模型 Genie 4，称其在物理模拟和人物表现上较 Genie 3 有明显提升，并借助 Google 更新的 Gemini 模型实现改进。该模型可根据指令逐帧实时生成可探索的虚拟世界，无需预先渲染场景或编写交互逻辑。DeepMind 表示，这类技术可用于为实体机器人构建训练环境，并支持创意领域的快速原型设计，付费用户有望较早用上 Genie 4。
DeepMind 公布 Genie 4 世界模型，宣称在物理与人物模拟上较 Genie 3 有提升，并可能开放付费使用，读者可据此了解世界模型的最新进展与定位。
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.
