Core Viewpoint - The limitations of large language models (LLMs) in understanding the physical world are highlighted, emphasizing that language is a generated signal dependent on human input, while the physical world is an objective reality governed by its own laws [1][5][19]. Group 1: Language Models and Their Limitations - Language models operate on a one-dimensional representation of discrete tokens, making them adept at handling written text but inadequate for representing the three-dimensional nature of the physical world [12][14]. - The challenge of spatial intelligence lies in extracting, representing, and generating information from the real world, which is fundamentally different from language processing [17][19]. - Experiments show that LLMs struggle with physical tasks, performing poorly compared to human children and specialized robots [22][28]. Group 2: Experimental Findings - In a test using the Animal-AI environment, LLMs could only complete simple tasks, failing at more complex ones even with additional teaching examples [26][27]. - A tool named ABench-Physics was developed to assess LLMs' physical reasoning abilities, revealing that even the best models achieved only a 43% accuracy rate on basic physics problems [30][34]. - Visual tasks further demonstrated the limitations of LLMs, with human accuracy at 95.7% compared to a maximum of 51% for the models [37][41]. Group 3: Philosophical and Future Considerations - The discussion includes perspectives on whether language can sometimes describe reality better than perception and the potential for AI to develop its own language for understanding the physical world [46][47]. - The ongoing development of models based on physical and multimodal understanding indicates a shift towards addressing these limitations [44].

Core Viewpoint - The article discusses the limitations of Large Language Models (LLMs) in software development, emphasizing that while LLMs can generate code and assist with simple tasks, they struggle with maintaining clear cognitive models necessary for complex problem-solving [5][14][15]. Group 1: LLM Capabilities - LLMs can perform routine engineering tasks such as reading code, writing tests, and debugging, but they often fail to maintain a coherent understanding of the code's behavior [8][15]. - They can generate code quickly and are effective in organizing requirement documents for straightforward tasks [15][16]. Group 2: Limitations of LLMs - LLMs cannot maintain two similar cognitive models simultaneously, which leads to confusion in determining whether to modify the code or the requirements [14][20]. - They often assume their generated code is flawless and struggle to adapt when tests fail, lacking the ability to validate their work against a clear mental model [9][14][22]. Group 3: Future Improvements - There is potential for improvement in LLMs, but significant changes to their underlying architecture are necessary to enhance their problem-solving capabilities beyond mere code generation [12][21]. - The article suggests that while LLMs currently have shortcomings, their rapid evolution indicates that they may become more competent in software development tasks in the future [21][22]. Group 4: Human vs. LLM Collaboration - The article advocates for human oversight in software development, asserting that LLMs should be viewed as tools rather than replacements for human engineers [17][19]. - It highlights the importance of human engineers in ensuring clarity in requirements and the actual effectiveness of the code produced [16][17].

清华金融评论· 2025-09-07 10:13
Core Viewpoint - The integration of large language models (LLMs) into the banking sector is driving digital transformation, but the inherent opacity of these models presents significant challenges in explainability, necessitating the establishment of a transparent and trustworthy AI application framework to ensure safe and compliant operations [3][4]. Regulatory Constraints on Explainability - Financial regulatory bodies are increasingly emphasizing the need for transparency in AI models, requiring banks to disclose decision-making processes to meet compliance standards and protect consumer rights, which serves as a primary external constraint on LLM applications [6]. - In scenarios like credit approval that directly affect customer rights, algorithmic decisions must provide clear justifications to ensure fairness and accountability. Regulations such as the EU's General Data Protection Regulation (GDPR) mandate transparency in automated decision-making, and domestic regulators also require banks to explain reasons for credit application rejections [7]. - Global regulatory trends are converging towards the necessity for AI model explainability, with frameworks like Singapore's FEAT principles and China's guidelines emphasizing fairness, ethics, accountability, and transparency. The upcoming EU AI Act will impose strict transparency and explainability obligations on high-risk financial AI systems [8]. Technical Explainability Challenges of LLMs - The architecture and operational mechanisms of LLMs inherently limit their technical explainability, as their complex structures and vast parameter counts create a "black box" effect [10]. - The attention mechanism, once thought to provide insights into model behavior, has been shown to have weak correlations with the importance of features in model predictions, undermining its reliability as an explanation tool. The sheer scale of parameters complicates traditional explanation algorithms, making it difficult to analyze high-dimensional models effectively [11]. - The phenomenon of "hallucination," where LLMs generate plausible but factually incorrect content, exacerbates the challenge of explainability. This issue leads to outputs that cannot be traced back to reliable inputs or training data, creating significant risks in financial contexts [12].

Core Insights - The article discusses the significant data pollution in AI language models, particularly highlighting that GPT-4o is more familiar with the Japanese adult film star "Yui Hatano" than with the common Chinese greeting "Hello," with a familiarity ratio of 2.6 times [2][54]. Group 1: Data Pollution in AI Models - A recent study from Tsinghua University, Ant Group, and Nanyang Technological University reveals that all major language models exhibit varying degrees of data pollution, particularly with "Polluted Chinese Tokens" (PoC Tokens) that often relate to adult content and online gambling [3][5]. - Over 23% of long Chinese tokens (containing two or more characters) in GPT-4o's vocabulary are associated with pornography or online gambling, indicating a significant presence of undesirable content [24]. - The study utilized tools like POCDETECT and POCTRACE to analyze the prevalence of polluted tokens across various language models, finding that GPT-4o has a pollution rate of 46.6% for long Chinese tokens, which is notably higher than other models [45][46]. Group 2: Implications of Data Pollution - The presence of polluted tokens not only poses risks to AI's reliability but also affects user experience, leading to nonsensical or irrelevant outputs when users query certain terms [6][11]. - The study suggests that the high frequency of these polluted tokens in training data results in AI models developing a "muscle memory" for these terms without understanding their meanings, leading to confusion and hallucinations in responses [28][30]. - The article emphasizes that the issue of data pollution reflects broader problems in the digital content environment, where AI is fed a continuous stream of low-quality information, ultimately mirroring the state of the internet [66][75].
