高分模型未必懂科学，有的只是在「死记硬背」！MIT揭秘：模型越聪明，对物质的理解就越趋同。既然真理路径已清晰，我们何必再深陷昂贵的算力竞 赛？ 现在的AI for Science，就像一场「多国峰会」，大家用不同的语言描述同一件事。 有人让AI读SMILES字符串，有人给AI看原子的3D坐标，大在不同的赛道上比谁预测得准。 但有一个问题：这些AI是在「找规律」，还是真的理解了背后的物理真相？ 在MIT的一项研究中，研究员把59个「出身」不同的模型凑在一起，观察它们在理解物质时，隐藏层表达是否相同 。 论文链接：https://arxiv.org/abs/2512.03750 结果非常惊人：虽然这些模型看数据的方式天差地别，但只要它们变得足够强大，它们对物质的理解就会变得极度相似 。 更神奇的是，一个读文字的代码模型，竟然能和一个算受力的物理模型在「认知」上高度对齐 。 它们沿着不同的路，爬到了同一座山峰的顶端，开始共同描绘物理与现实的「终极地图」。 真理的汇合：为什么顶尖模型越长越像？ 为了验证这些模型是否真的在靠近真理，研究者引入了一个关键指标：表征对齐度。 简单来说，就是看两个模型在处理同一个分子时，它们 ...

Core Insights - The article discusses the surprising creativity of AI models, particularly diffusion models, which seemingly generate novel images rather than mere copies, suggesting that their creativity is a byproduct of their architectural design [1][2][6]. Group 1: AI Creativity Mechanism - Diffusion models are designed to reconstruct images from noise, yet they produce unique compositions by combining different elements, leading to unexpected and meaningful outputs [2][4]. - The phenomenon of AI generating images with oddities, such as extra fingers, is attributed to the models' inherent limitations, which force them to improvise rather than rely solely on memory [12][19]. - The research identifies two key principles in diffusion models: locality, where the model focuses on small pixel blocks, and equivariance, which ensures that shifts in input images result in corresponding shifts in output [8][9]. Group 2: Mathematical Validation - Researchers developed the ELS (Equivariant Local Score) machine, a mathematical system that predicts how images will combine as noise is removed, achieving a remarkable 90% overlap with outputs from real diffusion models [13][18]. - This finding suggests that AI creativity is not a mysterious phenomenon but rather a predictable outcome of the operational rules of the models [18]. Group 3: Biological Parallels - The study draws parallels between AI creativity and biological processes, particularly in embryonic development, where local responses lead to self-organization, sometimes resulting in anomalies like extra fingers [19][21]. - It posits that human creativity may not be fundamentally different from AI creativity, as both stem from a limited understanding of the world and the ability to piece together experiences into new forms [21][22].

Core Viewpoint - The article discusses the competition between two major paradigms in generative AI: Diffusion Models and Autoregressive (AR) Models, highlighting the emergence of Diffusion Language Models (DLMs) as a potential breakthrough in the field of large language models [2][3]. Group 1: DLM Advantages Over AR Models - DLMs offer parallel generation capabilities, significantly improving inference speed by achieving a tenfold increase compared to AR models, which are limited by token-level serial processing [11][12]. - DLMs utilize bidirectional context, enhancing language understanding and generation control, allowing for finer adjustments in output characteristics such as sentiment and structure [12][14]. - The iterative denoising mechanism of DLMs allows for corrections during the generation process, reducing the accumulation of early errors, which is a limitation in AR models [13]. - DLMs are naturally suited for multimodal applications, enabling the integration of text and visual data without the need for separate modules, thus enhancing the quality of joint generation tasks [14]. Group 2: Technical Landscape of DLMs - DLMs are categorized into three paradigms: Continuous Space DLMs, Discrete Space DLMs, and Hybrid AR-DLMs, each with distinct advantages and applications [15][20]. - Continuous Space DLMs leverage established diffusion techniques from image models but may suffer from semantic loss during the embedding process [20]. - Discrete Space DLMs operate directly on token levels, maintaining semantic integrity and simplifying the inference process, making them the mainstream approach in large parameter models [21]. - Hybrid AR-DLMs combine the strengths of AR models and DLMs, balancing efficiency and quality for tasks requiring high coherence [22]. Group 3: Training and Inference Optimization - DLMs utilize transfer learning to reduce training costs, with methods such as initializing from AR models or image diffusion models, significantly lowering data requirements [30][31]. - The article outlines three main directions for inference optimization: parallel decoding, masking strategies, and efficiency technologies, all aimed at enhancing speed and quality [35][38]. - Techniques like confidence-aware decoding and dynamic masking are highlighted as key innovations to improve the quality of generated outputs while maintaining high inference speeds [38][39]. Group 4: Multimodal Applications and Industry Impact - DLMs are increasingly applied in multimodal contexts, allowing for unified processing of text and visual data, which enhances capabilities in tasks like visual reasoning and joint content creation [44]. - The article presents various case studies demonstrating DLMs' effectiveness in high-value vertical applications, such as code generation and computational biology, showcasing their potential in real-world scenarios [46]. - DLMs are positioned as a transformative technology in industries, with applications ranging from real-time code generation to complex molecular design, indicating their broad utility [46][47]. Group 5: Challenges and Future Directions - The article identifies key challenges facing DLMs, including the trade-off between parallelism and performance, infrastructure limitations, and scalability issues compared to AR models [49][53]. - Future research directions are proposed, focusing on improving training objectives, building dedicated toolchains, and enhancing long-sequence processing capabilities [54][56].
