刚刚，「Dreamer」大神Danijar Hafner，宣布离开他曾工作近十年的谷歌。 离职前Danijar担任Google DeepMind旧金山分部的资深研究科学家（Staff Research Scientist）。 他的研究目标是「构建能够理解世界并与世界互动的通用智能体」。 作为谷歌世界模型大牛，Danijar曾主导/联合主导了Dreamer系列（Dreamer、DreamerV3、Dreamer4 等）的开发。 Danijar Hafner 他在推文中写道：「今天是我在DeepMind的最后一天」。 回顾了在Google和DeepMind将近10年的工作经历，Danijar认为「一个重要的篇章走到了终点」。 Danijar在谷歌的早期经历，多是以研究员的身份参与谷歌研究院、DeepMind、Brain Team等团队的工作。 从他的教育经历中，也能清晰看出他的职业发展轨迹。 | Researcher 研究员 | Google (google.com) | | 2023 - Present | | --- | --- | --- | --- | | 谷歌 (google.com) | | | 20 ...

Core Viewpoint - The article discusses the significant advancements brought by Google's DeepMind with the release of Genie 3, which showcases a new path towards Artificial General Intelligence (AGI) through the concept of "World Models" [4][5][6]. Group 1: Introduction of Genie 3 - On August 5, Google DeepMind launched Genie 3, a model capable of generating interactive 3D virtual environments based on user prompts, demonstrating enhanced real-time interaction capabilities compared to previous AI models [5]. - Genie 3 features a "Promptable World Events" function, allowing users to dynamically alter the generated environment through text commands, showcasing its advanced interactivity [5]. Group 2: Concept of World Models - World Models are inspired by the human brain's ability to create and utilize an "inner world" to simulate future scenarios, which is crucial for decision-making and action [8][9]. - The development of World Models has evolved from early attempts to mimic human cognitive functions to more sophisticated models that can predict and simulate real-world dynamics [10][11]. Group 3: Technical Implementation of World Models - The implementation of World Models involves several key stages: Representation Learning, Dynamic Modelling, Control and Planning, and Result Output, each contributing to the AI's ability to understand and interact with the world [15][16][17][18]. - Representation Learning allows AI to compress external data into an internal language, while Dynamic Modelling enables the simulation of future scenarios based on actions taken [15][16]. Group 4: Applications of World Models - World Models can significantly enhance "embodied intelligence," allowing AI agents to learn through simulated experiences in a safe environment, reducing costs and risks associated with real-world trials [20][21]. - In the realm of digital twins, World Models can create proactive simulations that predict changes and optimize processes in real-time, enhancing automation and decision-making [21][22]. - The education and research sectors can benefit from World Models by creating virtual laboratories for precise predictions and interactive learning environments [22]. Group 5: Potential and Challenges of World Models - While World Models present vast potential for various applications, they also raise ethical and governance concerns, such as the blurring of lines between reality and virtuality, and the potential for behavioral manipulation [24][25][26]. - The debate surrounding World Models as a pathway to AGI highlights differing opinions within the AI community, with some experts advocating for their necessity while others question their effectiveness compared to model-free approaches [28][29][30].

Group 1 - Google DeepMind released a new model called Genie 3, which can generate interactive 3D virtual environments based on user prompts, showcasing enhanced real-time interaction capabilities compared to previous AI models [2] - Genie 3 introduces a feature called "Promptable World Events," allowing users to dynamically alter the generated environment through text commands, significantly expanding user interaction possibilities [2] - The performance of Genie 3 has sparked discussions about "World Models," which represent a potential pathway towards achieving Artificial General Intelligence (AGI) [2] Group 2 - The concept of "World Models" is inspired by the human brain's ability to create and utilize an "inner world" for predictive capabilities, allowing individuals to simulate future scenarios based on current inputs [4][5] - Historical attempts to replicate this capability in AI include early models that used feedback control theories and symbolic reasoning, evolving through the integration of statistical learning methods [6][7] - The term "World Model" was coined by Jürgen Schmidhuber in 1990, emphasizing the need for AI to understand and simulate the real world comprehensively [7] Group 3 - The implementation of World Models involves several key stages: representation learning, dynamic modeling, control and planning, and result output, each contributing to the AI's ability to simulate and interact with the environment [11][12][13][14] - World Models can significantly enhance various fields, including embodied intelligence, digital twins, education, and gaming, by allowing AI to actively engage and learn from simulated environments [15][16][17] Group 4 - The emergence of World Models has raised ethical and governance concerns, particularly regarding the potential blurring of lines between reality and virtuality, as well as the implications for user behavior and societal norms [18][19][20] - Experts in the AI field are divided on the necessity of World Models for achieving AGI, with some advocating for their importance while others suggest alternative approaches may suffice [21][22][23][24] Group 5 - The exploration of World Models represents a significant challenge to understanding cognition and the mechanisms of reality, positioning AI as a participant in the age-old quest to comprehend the workings of the world [25]
