Core Viewpoint - The article discusses the advancements and differences between Vision-Language-Action (VLA) models and World Models in the context of autonomous driving, emphasizing that while VLA is currently dominant, World Models possess inherent advantages in understanding and predicting physical realities [3][4][30]. Group 1: VLA vs. World Models - VLA currently dominates the market, with over 95% of global models generating videos for autonomous driving training rather than direct application [3]. - World Models are considered to have a significant theoretical advantage as they enable end-to-end learning without relying on language, directly linking perception to action [3][4]. - Proponents of World Models argue that they can understand the physical world and infer causal relationships, unlike VLA, which primarily mimics learned patterns [4][6]. Group 2: Development and Architecture - The World Model framework consists of three main modules: Vision Model (V), Memory RNN (M), and Controller (C), which work together to learn visual representations and predict future states [11]. - The architecture of World Models has evolved, with notable developments like RSSM and JEPA, which focus on combining deterministic and stochastic elements to enhance performance [15][17]. - JEPA, introduced in 2023, emphasizes predicting abstract representations rather than pixel-level details, significantly reducing computational requirements [17][19]. Group 3: Advantages and Challenges - World Models have two main advantages: they require less computational power than VLA and can utilize unlabelled data from the internet for training [19]. - However, challenges remain, such as the need for diverse and high-quality data to accurately understand physical environments, and the limitations of current sensors in capturing all necessary information [19][20]. - Issues like representation collapse and error accumulation in long-term predictions pose significant hurdles for the effective deployment of World Models [21][22]. Group 4: Future Directions - The integration of VLA and World Models is seen as a promising direction, with frameworks like IRL-VLA combining the strengths of both approaches for enhanced performance in autonomous driving [22][28]. - The article suggests that while VLA is likely to prevail in the near term, the combination of VLA with World Model enhancements could lead to superior outcomes in the long run [30].

Core Viewpoint - The current large language models (LLMs) are limited in their ability to generate original scientific discoveries and truly understand the complexities of the physical world, primarily functioning as advanced pattern-matching systems rather than exhibiting genuine intelligence [1][3][4]. Group 1: Limitations of Current AI Models - Relying solely on memorizing vast amounts of text is insufficient for fostering true intelligence, as current AI architectures struggle with abstract thinking, reasoning, and planning, which are essential for scientific discovery [3][5]. - LLMs excel at information retrieval but are not adept at solving new problems or generating innovative solutions, highlighting their inability to ask the right questions [6][19]. - The expectation that merely scaling up language models will lead to human-level AI is fundamentally flawed, with no significant advancements anticipated in the near future [19][11]. Group 2: The Need for New Paradigms - There is a pressing need for new AI architectures that prioritize search capabilities and the ability to plan actions to achieve specific goals, rather than relying on existing data [14][29]. - The current investment landscape is heavily focused on LLMs, but the diminishing returns from these models suggest a potential misalignment with future AI advancements [18][19]. - The development of systems that can learn from natural sensors, such as video, rather than just text, is crucial for achieving a deeper understanding of the physical world [29][37]. Group 3: Future Directions in AI Research - The exploration of non-generative architectures, such as Joint Embedding Predictive Architecture (JEPA), is seen as a promising avenue for enabling machines to abstractly represent and understand real-world phenomena [44][46]. - The ability to learn from visual and tactile experiences, akin to human learning, is essential for creating AI systems that can reason and plan effectively [37][38]. - Collaborative efforts across the global research community will be necessary to develop these advanced AI systems, as no single entity is likely to discover a "magic bullet" solution [30][39].
