📚 Learning
Why is Knowledge Distillation (KD) Effective? New Research Offers a Concise Explanation: Kyunghyun Cho et al. propose a concise explanation for the effectiveness of Knowledge Distillation (KD). They hypothesize that using low-entropy approximate sampling from a teacher model leads to student models with higher precision but lower recall. Since autoregressive language models are essentially infinitely cascaded mixture distributions, they validated this hypothesis through SmolLM.

Microsoft Proposes CoML: Chain-of-Model Learning for Language Models: Microsoft Research has proposed a new learning paradigm called “Chain-of-Model Learning” (CoML). This method incorporates the causal relationships of hidden states into each network layer in a chain-like structure, aiming to improve the scaling efficiency of model training and the inference flexibility during deployment. Its core concept, “Chain-of-Representation” (CoR), decomposes the hidden state of each layer into multiple sub-representation chains, where subsequent chains can access the input representations of all preceding chains. This allows the model to be progressively scaled by adding chains and to provide multiple sub-models of varying sizes for elastic inference by selecting different numbers of chains. CoLM (Chain-of-Language Model) and its variant CoLM-Air (which introduces a KV sharing mechanism), designed based on this principle, have demonstrated performance comparable to standard Transformers while offering the advantages of progressive scaling and elastic inference (Source: X, HuggingFace Daily Papers)
Differences and Connections Between Deep Learning, Generative, and Embedding Models: An explanatory article clarifies the relationships between deep learning models, generative models, and embedding models.

Based on this, they proposed Fractured Sampling, a unified reasoning strategy. By adjusting three dimensions—the number of reasoning trajectories, the number of final solutions per trajectory, and the truncation depth of reasoning traces—they achieved a better accuracy-cost trade-off across multiple reasoning benchmarks and model scales, paving the way for more efficient and scalable LLM inference (Source: HuggingFace Daily Papers)

The Rise of AI Programming Agents Sparks Discussion on Programmers’ Career Prospects: Companies like Microsoft and OpenAI are launching or enhancing AI programming agents (Coding Agents), such as GitHub Copilot Coding Agent and OpenAI Codex, which can autonomously complete coding, fix bugs, and maintain code. Anthropic CEO Dario Amodei predicts AI might write most or even all code in the short term, and OpenAI CPO Kevin Weil also believes AI will evolve from junior engineers to architects. This has triggered widespread community discussion about the future of programmers’ careers: some worry that junior positions will be replaced and AI will automate a large amount of programming work; others believe AI will enhance programmers’ efficiency, allowing them to focus on higher-level architectural design and innovation, transforming their roles into “AI guides.” The overall trend suggests that learning to collaborate effectively with AI will become a core skill for programmers (Source: X, X, 36Kr, 36Kr)
Heated Discussion on AI Agent Concepts and Standards, MCP Protocol Gains Attention: With the rise of AI Agent applications (such as Manus, Genspark Super Agent, Fellou.ai), the community is actively debating the definition, capability levels, and development paradigms of Agents. Prominent VC firm BVP proposed a seven-level classification for Agents, from L0 to L6. Meanwhile, the Model Context Protocol (MCP) is gaining attention as a key technology for achieving interoperability between AI applications. Major international companies like Anthropic, OpenAI, and Google have supported or plan to support MCP, while domestic players like Alibaba Cloud and Tencent Cloud are also starting to build localized Agent development platforms around MCP. Developer iluxu even open-sourced a similar project, llmbasedos, before Microsoft proposed its “USB-C for AI apps” concept, aiming to promote open Agent connection standards (Source: X, X, WeChat, Reddit r/LocalLLaMA)
LLMs Underperform on Specific Reasoning Tasks, Sparking Debate on Their Capability Boundaries: The community is hotly debating the phenomenon of LLMs collectively “failing” on some seemingly simple physical or visuospatial reasoning tasks. For example, a question about stacking cubes to form a larger cube stumped even top models like o3 and Gemini 2.5 Pro. Concurrently, an evaluation article pointed out that on basic physical tasks like parts manufacturing, LLMs (including o3) perform worse than experienced workers, mainly due to insufficient visual capabilities, physical reasoning errors, and a lack of real-world tacit knowledge. These cases have sparked discussions about LLMs’ true understanding capabilities, hallucination issues (e.g., o3’s increased hallucination rate during reasoning), and the validity of current benchmarks, emphasizing that AI still has significant room for improvement in domain-specific knowledge and complex reasoning (Source: QbitAI, 36Kr)
Sino-US Tech Competition and AI Development Strategies Draw Attention: In an interview, NVIDIA CEO Jensen Huang discussed chip regulations, AI factories, and enterprise pragmatism. His views were interpreted as profound insights into the current Sino-US tech competition landscape. Some commentators believe that the US is trying to maintain its lead by restricting China’s access to high-end AI resources, but this could lead to a lose-lose situation, slowing down global AI development. Huang, however, seems to believe that the real competition is long-term, and the US should aim for comprehensive leadership (chips, factories, infrastructure, models, applications), rather than just seeking short-term relative advantages, otherwise it might miss the development opportunities of the AI era and ultimately fall behind in comprehensive national strength competition (Source: X)
Application and Discussion of AI Tools like ChatGPT for Mental Health Support: Reddit community users shared experiences using AI tools like ChatGPT for mental health support, believing they can provide help between professional therapy sessions, especially in articulating and understanding complex emotions. Users ask AI questions or have AI ask them questions about their feelings to better understand emotional sources and develop improvement plans. In the comments, some users (including self-proclaimed therapists) believe AI can be even better than some human therapists in certain situations, especially for individuals who have difficulty accessing professional help or have trust issues with human therapists. However, other users cautioned that AI cannot completely replace professional treatment and that personal data privacy should be a concern (Source: Reddit r/ChatGPT)

Chicago Sun-Times AI-Generated Content Errs, Recommends Non-Existent Books and Experts: In a summer activity recommendation section, the Chicago Sun-Times published content suspected to be AI-generated, which included recommendations for fictional books by real authors and quoted “experts” who seemingly do not exist. For example, it listed Min Jin Lee’s “Nightshade Market” and Rebecca Makkai’s “Boiling Point” as recommended reads, but these books do not exist. This incident has raised concerns about the accuracy and vetting mechanisms of news media using AI-generated content (Source: Reddit r/artificial)
Discussion on Whether Using AI Constitutes “Cheating”: The community discussed the boundaries of using AI tools (like ChatGPT, Claude) in work and study. The prevailing view is that, in the absence of explicit rules prohibiting it (such as in university assignments), using AI tools to improve efficiency, complete repetitive tasks, or assist thinking is not “cheating,” but rather akin to using a calculator or search engine. The key is whether the user understands the AI’s output, can effectively adjust and validate it, and honestly declares the AI’s assistive role (especially in academic settings). However, if one completely relies on AI-generated content and claims it as original without discernment, it may involve academic misconduct or hinder personal skill development (Source: Reddit r/ArtificialInteligence)
