DeepMind 公佈 Genie 4 世界模型，主打更真實的物理效果與人類
DeepMind unveils Genie 4 world model promising more realistic physics and humans
Google DeepMind 公佈 Genie 4 世界模型，稱新模型幾乎各方面都較 Genie 3 有所改進，並能呈現更真實的物理效果與人類。模型會按提示詞即時逐格生成虛擬世界，供用戶探索，無須預先渲染環境或編寫互動元素。DeepMind 表示，這項技術可建立機械人訓練環境，亦可用於創意領域的快速原型製作。
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.
