1. Autoregressive Models and Error Accumulation and Dynamic Correction in Autoregressive Reasoning Models
Autoregressive models generate each token sequentially when producing reasoning answers. Although each step is based on probabilistic sampling and may introduce slight deviations, these fluctuations do not necessarily accumulate monotonically into a complete error. In fact, each sampling step has the opportunity to correct previous deviations—much like an experienced driver continuously making subtle adjustments to the steering wheel to stay on course. This inherent self-correcting mechanism is a key reason why large models like GPT can generate coherent and smooth text. The "negative-negative yields positive" effect outweighs any error accumulation, which is the secret behind the autoregressive generation process and a core factor in GPT’s success. Specifically, regarding long chain-of-thought reasoning models, we note the following:
Dynamic Correction Potential: Recent research indicates that despite slight deviations during reasoning, a significant portion of logical errors can be automatically corrected in subsequent steps. This demonstrates that the model has an intrinsic ability to “backtrack” and reflect on its process, allowing for real-time adjustments to minor errors.
Task Dependency: In high-level abstract reasoning, where there are fewer clearly verifiable intermediate steps, deviations may appear more pronounced (Deductive Beam Search: Decoding Deducible Rationale for Chain-of-Thought Reasoning). In contrast, in strictly symbolic reasoning tasks (such as arithmetic), where clear verification rules exist, the model can more easily use feedback from the results to promptly correct deviations, thereby maintaining high accuracy.
Practice in DeepSeek R1: DeepSeek R1 has demonstrated abilities akin to “epiphanies” or self-validation during training, enabling it to detect and correct errors in the generation process to some extent (Improving LLM Reasoning with Chain-of-Thought, Context-Aware ...). This capability serves as a beneficial complement to the criticism that models merely “pad” with length when depth is insufficient.
2. Tool Use vs. Long Chain-of-Thought: Efficiency Trade-offs
Integrating external tool calls (e.g. calculators, code interpreters, or APIs like Wolfram|Alpha) offers an alternative to very long CoT reasoning, often yielding gains in accuracy and efficiency. For tasks such as complex math, factual queries, or code execution, calling specialized tools can dramatically improve reliability. Studies show that augmenting GPT-4 with a math solver (Wolfram Alpha) or a Python execution plugin significantly enhances problem-solving performance on challenging science/math questions (Testing GPT-4 with Wolfram Alpha and Code Interpreter plug-ins on math and science problems). The model can offload exact computation to the tool, avoiding arithmetic errors or hallucinated facts. This division of labor also helps with load management: the LLM doesn’t need to “think through” laborious calculations token by token, which can reduce the computational load per query. In many cases, one API call is faster and more cost-effective than generating a lengthy step-by-step solution, especially when the CoT would span hundreds of tokens. However, tool use introduces latency from the call itself and potential integration issues. One evaluation noted frequent “interface failures” where the LLM struggled to formulate the proper query for the tool or misinterpreted the result (Testing GPT-4 with Wolfram Alpha and Code Interpreter plug-ins on math and science problems). Thus, while API calls can improve accuracy, ensuring the model knows when and how to invoke tools is an active area of research (e.g. Meta’s Toolformer taught LLMs to insert API calls in their text autonomously (Can language models make their own tools? - Deep (Learning) Focus)).
There is also a trade-off in strategy between relying on pure neural reasoning versus a code-generation+execution approach. Instead of extending the chain-of-thought indefinitely, an LLM can generate a piece of code (a “solution program”) to compute the answer, and then run it. This approach, used in Program-Aided Language Models (PAL), offloads the final reasoning step to a Python interpreter (PAL (Program-Aided Language Models) | Prompt Engineering Guide ). For example, rather than reasoning through a date calculation step by step in English, the model writes a short Python script to do it and executes it for the exact answer. Empirically, this method often outperforms long natural-language reasoning in both accuracy and reliability (PAL (Program-Aided Language Models) | Prompt Engineering Guide ). Recent prompting techniques like Program-of-Thought (PoT) have demonstrated ~15% accuracy boosts on math word problems by having the model produce structured code as the reasoning medium instead of free-form text (Program of Thoughts Prompting: Enhancing Accuracy in Reasoning ...). The adaptability of these approaches depends on the task: if a problem can be cleanly turned into an algorithm, code execution is ideal (ensuring correctness and speed). On more abstract or commonsense tasks where formalizing steps into code is hard, a natural-language CoT (potentially with tool calls for subtasks) may be more flexible. In practice, many advanced systems combine both: they generate a mix of explanation and code (or API usage) as needed. Overall, tool integration (calculators, search engines, code runners) tends to improve accuracy and reduce the cognitive load on the model, at the expense of added system complexity and slight latency – a worthwhile trade-off for many high-stakes applications (Testing GPT-4 with Wolfram Alpha and Code Interpreter plug-ins on math and science problems) (MathViz-E - Agent Tool Control - Emergence AI).
3. Reinforcing Logical Density Through Code & Structured Reasoning
One promising path to bolster an LLM’s logical reasoning ability is training on code and other logically-dense data. Code is inherently structured and unforgiving of mistakes, so it provides a form of “logical calibration” for language models. Recent research confirms a strong leverage effect of code corpora on reasoning performance: including a proportion of programming data in pre-training leads to notable gains on logic and math tasks, far beyond coding questions alone (At Which Training Stage Does Code Data Help LLMs Reasoning? | OpenReview). For instance, an ICLR 2024 study found that pre-training on a mix of text and code “significantly enhances” a model’s general reasoning capabilities without hurting its language skills (At Which Training Stage Does Code Data Help LLMs Reasoning? | OpenReview). Models exposed to code learn patterns of step-by-step problem solving (e.g. planning, function usage, precise conditionals) that transfer to non-coding problems. In practice, we see this in models like OpenAI’s GPT-4 (heavily trained on code) which excel at multi-step logic puzzles and mathematical reasoning compared to earlier models. Furthermore, using code data in the fine-tuning stage can endow an LLM with task-specific reasoning skills (At Which Training Stage Does Code Data Help LLMs Reasoning? | OpenReview). For example, fine-tuning on code-based solutions for math problems can teach the model to imitate those structured solutions. Overall, boosting the “logic density” of training data (through code, structured math proofs, etc.) has a high ROI in terms of reasoning ability – the model becomes more systematic and less prone to fuzzy errors ([R] Large Language Models trained on code reason better ... - Reddit).
Beyond data, researchers are also exploring architectural innovations to inject structured logical units into neural models. The frontier of neuro-symbolic AI aims to blend neural networks with symbolic logic systems in a differentiable manner. One approach is to design modules within the network that perform constrained logical operations. A recent position paper advocates for Logical Neural Units (LNUs) – components that embed differentiable versions of logical operators (AND, OR, NOT) directly into the model’s computation ([2502.02135] Standard Neural Computation Alone Is Insufficient for Logical Intelligence). The idea is to give the network a native ability to enforce logical consistency and rule-based reasoning, addressing weaknesses of purely neural approaches ([2502.02135] Standard Neural Computation Alone Is Insufficient for Logical Intelligence). With such structured units, an LLM’s intermediate representations could handle boolean logic or arithmetic with higher fidelity, reducing errors on tasks requiring strict logical steps. Similarly, new neuro-symbolic frameworks like Differentiable Logic Machines allow learning first-order logic programs with gradient-based training (Differentiable Logic Machines | OpenReview). These systems maintain an interpretable logical layer (e.g. a set of learned rules) while training the whole model end-to-end. Early results show that these hybrids can solve inductive logic programming tasks that stump standard LLMs (Differentiable Logic Machines | OpenReview). In summary, reinforcing logical reasoning can be tackled from two angles: (a) training data with high logical density (such as code) to impart systematic problem-solving skills, and (b) model architectures that explicitly incorporate symbolic reasoning elements. Both approaches are actively pushing the state of the art, making models more accurate and robust on complex reasoning challenges (At Which Training Stage Does Code Data Help LLMs Reasoning? | OpenReview) ([2502.02135] Standard Neural Computation Alone Is Insufficient for Logical Intelligence).
4. Recalibrating Commercial Deployment and ROI
When bringing advanced reasoning models into real-world applications, it’s crucial to match the technology to the use-case and consider economic viability. Not all reasoning tasks provide equal business value, and complex “general” reasoning may not always be the best fit commercially. A recalibration is underway as organizations assess where these models genuinely add value. High-level logical reasoning (like theorem proving or abstract planning) might impress technically, but its economic value density could be low if few practical workflows require it. On the other hand, more constrained reasoning in domains like financial analytics, medical Q&A, or code generation can have clear ROI by automating costly expert tasks. The key is to evaluate each potential application for technical feasibility and business impact. For example, in customer support automation, a reasoning LLM that can navigate a product knowledge base and solve customer issues has a direct economic benefit (cost savings, faster service). However, it needs a high reliability threshold. In contrast, using an LLM for open-ended strategic advice might be technically possible but harder to trust or quantify in value. Matching the right model and method to each scenario is therefore essential – in some cases a smaller, fine-tuned model or even a rules-based system might suffice (and be more cost-effective) than a giant general reasoning model.
Another consideration is the integration cost and infrastructure needed to deploy these models responsibly. Industry analyses have noted that simply having a powerful LLM is not enough to guarantee ROI; success comes from surrounding the model with the proper data and tools (LLMs alone won't generate positive ROI, but this will...). In practical terms, that means businesses must invest in data preparation (clean, well-organized knowledge sources), define clear objectives for the AI (what KPI or outcome it’s improving), and build supporting systems for monitoring and error handling. ROI is maximized when the model operates within a well-designed pipeline: for instance, an LLM-powered assistant should interface with databases via APIs, incorporate user context, and have fallback rules for uncertainty. One report emphasizes that achieving ROI involves clear goals, organized data, appropriate APIs, robust security, and scalability – essentially treating the LLM as one component in a larger solution (LLMs alone won't generate positive ROI, but this will...). If this alignment is done, the payoff can be substantial. Case studies have shown triple-digit percentage returns in certain automation projects once the LLM was fine-tuned to the domain and properly integrated (LLMs alone won't generate positive ROI, but this will...) (Leadership Perspectives: Use Cases and ROI of LLMs - AI Forward | Fiddler AI). On the flip side, deploying an overly powerful reasoning model without focus can rack up cloud costs and risk failures, undermining economic gains. The recommendation is to start with high-value, well-bounded use cases: e.g. using a code-generation model as a “copilot” for developers (increasing productivity), or an LLM to triage support tickets. These scenarios have both clear technical requirements and measurable value (time saved, higher throughput), making it easier to justify investment. Over time, as the technology improves, the range of economically viable reasoning tasks will expand. For now, successful commercial adoption requires a careful calibration of ambition vs. practicality – leveraging these models where they truly augment human work and rigorously evaluating the return on each deployment (Leadership Perspectives: Use Cases and ROI of LLMs - AI Forward | Fiddler AI).
5. Future Outlook: Neuro-Symbolic Integration and AI Middleware
Looking ahead, the evolution of neuro-symbolic systems is poised to play a central role in pushing reasoning AI to the next level. Purely neural LLMs, even very large ones, still struggle with certain types of systematic reasoning and long-horizon planning. The frontier consensus is that hybrid approaches (combining neural and symbolic methods) could overcome these limitations ([2502.02135] Standard Neural Computation Alone Is Insufficient for Logical Intelligence). We anticipate research that further optimizes symbolic computation layers within AI models – for example, an LLM might internally invoke a symbolic theorem prover or a knowledge graph query module when needed. This could allow it to handle tasks like verifying a mathematical proof or ensuring logical consistency of an answer by calling on an exact, rule-based system embedded in its architecture. Such a neural-symbolic synergy would let the AI reason with the creativity of neural networks and the precision of symbolic logic. Early signs of this trend include models capable of reading formal logic statements or performing algebraic manipulations by integrating external solvers into their reasoning loop (SymbolicAI: A framework for logic-based approaches combining generative models and solvers) (Towards a Middleware for Large Language Models). In the coming years, we might see “reasoning co-processors” attached to LLMs: differentiable modules specialized for arithmetic, formal logic, or even database-style querying, all trainable as part of the larger model. This neuro-symbolic route could dramatically improve the trustworthiness of AI reasoning by reducing hallucinations and ensuring critical steps are verifiable.
Another forward trend is the emergence of AI-native middleware and tool ecosystems that surround LLMs. Rather than treating tool use as a hack or afterthought, future AI systems will likely have robust frameworks for orchestrating external calls and subtasks. We are already seeing the beginnings of this with platforms like LangChain (which helps structure multi-step AI workflows) and OpenAI’s function calling API. The tool invocation ecosystem is being reimagined: instead of a loose collection of plugins, there may be a formal registry of tools that an AI agent can consult, complete with standardized interfaces and permission controls (Towards a Middleware for Large Language Models). Researchers have outlined visions of an LLM-centric middleware where the model serves as a intelligent controller that parses user requests, then dynamically routes subtasks to various services (web search, calculators, databases, etc.) (Towards a Middleware for Large Language Models). In such architectures, the LLM essentially becomes the new “operating system” for complex queries – it decides how to break down a problem and which API or micro-service to call for each part. This is a shift towards AI as an orchestrator: the model is not just answering questions, but managing flows of information between tools. The advantages would be greater reliability and scalability. For example, if a query requires factual lookup, the system might automatically use a knowledge base tool, whereas a math query triggers a computational engine. The heavy lifting is done by specialized modules, while the LLM focuses on understanding context and synthesizing the final answer.
Ecologically, this means the tool-calling ecosystem will become more structured and robust. We expect standards to emerge for how tools declare their capabilities to an AI, how the AI maintains state across calls, and how results are verified. Already, proposals exist for middleware layers that include a service registry, scheduler, and execution graph manager specifically for LLM-driven applications (Towards a Middleware for Large Language Models). In practice, this could resemble an AI agent that knows when to “ask” a calculator or a database and can plug the result back into its chain-of-thought seamlessly. As this ecosystem matures, developers will be able to “plug in” new tools (from graph solvers to web crawlers) into an AI’s repertoire without retraining it from scratch – the AI will learn via meta-training how to use any tool with a known interface. This modular, tool-augmented future pairs well with neuro-symbolic advances: some of those “tools” could be internal symbolic reasoners or smaller expert models. Together, these trends point toward more powerful and reliable AI reasoning systems. We can foresee an AI that, for example, tackles a complex scientific problem by drawing on neural intuition, querying a chemistry database, performing a numerical simulation, and logically verifying each step, all in a coordinated manner. In summary, the next wave of reasoning AI will likely blur the lines between model and tool, neural and symbolic – delivering systems that are far more capable of deep reasoning with the accuracy, speed, and trustworthiness needed for real-world impact ([2502.02135] Standard Neural Computation Alone Is Insufficient for Logical Intelligence) (Towards a Middleware for Large Language Models).

I’m pulling from AAOS, NASS, and the latest spine journals to clarify surgeries for cervical spondylosis, especially indicating nerve root compression or spinal cord compression.
I’m checking OrthoInfo, Mayo Clinic, and spine.org for guidelines and treatment options on cervical spine conditions.
The critical surgical indications for cervical spondylosis encompass severe radiculopathy unresponsive to conservative approaches, signs of spinal cord compression, and significant quality of life degradation due to these conditions.
I'm gathering insights from StatPearls, e-neurospine, and JC Neurosurg Sci, focusing on surgical indications for cervical radiculopathy and myelopathy.
I'm gathering info on whether "surgery vs conservative" should be recommended if radiculopathy persists beyond a certain point or shows progress. This aligns with a review of surgical indications for cervical spondylotic myelopathy.
I'm digging into established surgical indications for myelopathy, noting progression, duration, and compression ratio. Wondering if recent studies offer updated insights. Deine
Surgery is advised for patients with cervical spondylotic myelopathy (CSM) when persistent or severe radiculopathy emerges after at least 3 years of non-responsive conservative treatment.
I’m finding standard indications for surgery, such as unbearable pain, progressive neuro deficits, and leg involvement, to support or compare the latest surgical guidelines or those from reliable sources like Mayo or OrthoInfo.
OK, let me see. I'm verifying if the snippet matches Mayo Clinic's "Cervical spondylosis - Diagnosis & treatment" using domains like "amerikanhastanesi.org" or "kuh.ku.edu.tr."
Examining the second link, likely the Turkish site.
I'm gathering info on whether surgery might be needed for myelopathy or radiculopathy if conservative treatments fail or symptoms worsen. References include AAOS OrthoInfo, University of Maryland, and Mayo.
I’m pulling together patient case analyses and spine surgeons' advice on surgery timing, considering Western sources, and checking Chinese guidelines. This might involve articles, Q&A with surgeons, or the latest spine journals.
OK, let me see. For mild cases, managing or surgery might depend on factors. Moderate to severe often calls for surgery to halt progression.
I’m thinking through the importance of early surgical intervention in cases like degenerative cervical myelopathy, emphasizing minimizing long-term disability and enhancing quality of life.
Working through options for combining patient stories, expert blogs, and case series to highlight the significance of early intervention in severe myelopathy.
I'm noting a specific case, "A Case of Delayed Treatment in CSM," which might involve real life or simulated medical context.
Interestingly enough, the patient's earlier imaging two years ago pointed to stenosis, suggesting surgery. Despite the recommendation, surgery didn't happen until after a procedure two years later when she lost function on her right side.
I'm gathering authoritative sources, recent research, and expert opinions to ensure data accuracy and reliability. This involves consulting guidelines like AAOS and NASS, and referencing recent spinal medicine journals.
Noting that early surgical intervention is crucial for halting DCM progression and enhancing quality of life, emphasizing expert recommendations and timely intervention.
ACDF and laminectomy both relieve compression and improve symptoms. ACDF shows high success for arm pain relief, while laminectomy offers significant myelopathy symptom improvement.
I’m piecing together the process of scrolling through the document until I reach the "treatment" section, ensuring all necessary details and instructions are captured.
I'm gathering info on Cleveland for general stuff, focusing on: 1) Medications (NSAIDs, muscle relaxants), 2) Physical therapy, 3) Immobilization, 4) Nerve blocks, and 5) TENS.
Cervical radiculopathy responds well to conservative treatments such as medication, physical therapy (PT), and nerve blocks. External immobilization and heat therapy are less common but can be considered.
I'm considering detailing surgical indications for cervical spondylosis, highlighting nerve root compression, spinal cord compression, and severe quality of life impairment. Progressing to compare ACDF and laminectomy methods.
I'm gathering info on medication and physical therapy for degenerative cervical myelopathy. Also looking into the use of epidural steroid injections.

OpenAI GPT4.5 deep research 遇到一些麻烦,参照了太多的资料,似乎进入死循环,准备限定它的研究深度,重启 deep research,单独博客它的深度研究报告。
Since ChatGPT's explosive rise in 2022, artificial intelligence has rapidly transitioned from mere "chatbots" capable of responding to queries, to autonomous "agents" capable of executing tasks independently. In the emerging field of AI Agents, two architectural paradigms seem to have emerged: Compiled Agents and Interpreted Agents. Understanding their differences, capabilities, and limitations is essential for grasping the broader evolution of AI-driven productivity.
Compiled vs. Interpreted Agents
To simplify:
Compiled Agents embed intelligence predominantly during development, using pre-defined workflows and scripts. They excel in tasks with predictable outcomes.
Interpreted Agents dynamically apply intelligence at runtime, adjusting actions based on immediate context and feedback, suited to open-ended, unpredictable tasks.
Just as traditional software differentiates between compiled (pre-wired) and interpreted (runtime-decided) languages, AI agents exhibit similar distinctions.
Technical Deep Dive
Compilation in LLM: Parameter Fixation and Knowledge Internalization
In LLM-native agents, "compilation" occurs during model training. Vast textual data is compressed into fixed neural parameters. Post-deployment, these parameters act like "compiled" code, setting fixed probabilistic boundaries on potential behaviors.
Interpretation in AI: Dynamic Runtime Decisions
However, runtime inferences from LLMs reveal an "interpreted" quality, characterized by:
Adaptive path planning reacting to real-time feedback
Probabilistic decisions, allowing the same prompt to yield different outcomes
Thus, LLMs represent a hybrid computational paradigm, combining "probabilistic compilation" and "constrained interpretation"—leveraging pre-trained parameters while dynamically interpreting and adapting at runtime.
Examples: ByteDance's Coze platform exemplifies this model. Users visually design the agentic logic via drag-and-drop workflows, ensuring consistency and reliability. Ideal for well-defined business automation tasks like RPA (Robotic Process Automation), compiled agents excel in repeatable, predictable operations.
Limitations: Rigidity and inability to adapt dynamically. Any unforeseen changes in environment or input can disrupt workflows, necessitating manual reconfiguration and/or re-training the models behind.
Interpreted Agents: Runtime Autonomy and Flexibility
Interpreted agents are LLM-native autonomous agents that dynamically formulate and revise their execution plans:
Goal-driven, high-level task definitions
Real-time strategic planning
Environmental awareness
Autonomous decision-making with dynamic tool selection
Examples: Manus and AutoGPT embody interpreted agents. AutoGPT autonomously breaks tasks into subtasks, sequentially executes them, adapts based on interim results, and maintains persistent memory states to handle complex, multi-step operations. Manus, employing a multi-agent collaborative framework, autonomously executes complex workflows—from data analysis to report generation—demonstrating a complete "idea-to-execution" loop.
Strengths: Highly adaptive, capable of handling diverse, unforeseen scenarios. Ideal for research, creative tasks, and personal assistance.
Challenges: Unpredictability, higher computational resources, potential security risks, and more intricate development and testing procedures.
Interface Strategies: Universal vs. Specialized
Agent capabilities heavily depend on interaction modes with external environments:
Universal Interfaces (browser-like interactions) grant agents broad compatibility but face efficiency, reliability, and security issues.
Specialized Interfaces (API calls) offer speed, stability, and security but lack flexibility and require direct integration.
Strategically, agents leveraging specialized APIs can form more robust, defendable positions, avoiding easy internalization by LLM providers.
Future Directions and Challenges
Emerging Hybrid Architectures
Future agents will increasingly blend compiled reliability with interpreted adaptability, embedding runtime-flexible modules within structured workflows. Such hybrids combine precise business logic adherence with adaptive problem-solving capabilities.
Technical Innovations
Advances needed include:
Further enhanced runtime reasoning and self-reflection via RL (Reenforcement Learning) post-training to improve decision accuracy
Integrated multimodal perception (visual, auditory, tactile) for richer environmental understanding
Widespread agent deployment raises security, privacy, and ethical issues, demanding stringent governance, transparent operational oversight, and responsible AI guidelines.
Conclusion
Compiled and interpreted agents represent complementary, evolving paradigms. Their convergence into hybrid architectures is forming the backbone of a new, powerful LLM-native agent ecosystem. As this evolution unfolds, humans will increasingly delegate routine cognitive tasks to agents, focusing instead on strategic, creative, and emotionally intelligent roles, redefining human-AI collaboration.
In essence, the future of AI agents lies in balancing the precision and predictability of compilation with the flexibility and creativity of interpretation, forging an unprecedented path forward in human-technology synergy.
Manus is a new AI agent developed by the Chinese startup Monica, claiming to be the world's first fully autonomous AI agent. It's designed to handle complex tasks independently after an initial user prompt, such as sorting résumés, analyzing stock trends, and generating interactive websites. Currently, Manus is in a private testing phase, accessible by invitation only.
Xiao Hong is truly exceptional! Clear-minded, shrewd, and remarkably, he maintains both the right mindset and passion while drawing on years of accumulated experience. If I were an investor, I'd back him without hesitation.
I listened to Zhang Xiaojun's exclusive conversation with Manus CEO Xiao Hong in one sitting—fascinating throughout. Xiao Hong speaks plainly and honestly, without mystification or pretense, yet his insights are remarkably precise. He has crystal-clear awareness about positioning himself and his products, about the ecosystem, about the relationship between foundation models and applications, and about the future. As a 10-year entrepreneurial veteran, he maintains his own principles, staying true to himself ("be yourself"). While he fully understands that tech giants like ByteDance will quickly catch up in the large language model agent space, he believes there will always be room for application enthusiasts like himself. He consistently holds model companies in high regard, particularly highlighting how DeepSeek has brought unexpected positive factors to the application ecosystem.
The Man Behind Manus
Xiao Hong (Red) is the CEO of Manus, the recently viral large language model autonumous agent that has become China's new star in the AI industry following DeepSeek. Listening to Xiao Hong's interview feels like reading "startup notes" for the new era of AI applications. This founder, born in the 1990s but already with 10 years of entrepreneurial experience, not only clearly articulates the development trajectory of large language model applications but also explains in plain language to entrepreneurs: in this AI revolution, even if you're not a "model powerhouse" like DeepSeek or OpenAI, you can still find your place.
From Chatbots to Agents: The Evolution of AI Applications
The evolution of AI applications has been as dramatic as the shift from flip phones to iPhones:
Jasper Era: Homework-copying mindset, "Please fill in your target audience and theme~" ChatGPT Era: Conversational instructions, "Hi, what can I help you with?" Monica Era: Context awareness, "I see you're reading this article, would you like me to summarize it for you?" Cursor Era: Vertical coding agent, "I don't just chat, I can write code to solve your problems!" Agent Era: Asynchronous planning and execution, "Let me break down this task, complete it step by step, and report results as they come~"
Isn't this just like the evolution from "feature phones" to "smartphones"? Xiao Hong discovered a clear main thread behind this evolution: increasingly aligning with ordinary people's habits while expanding capability boundaries in values.
"The New Andy-Bill Law": How Application Companies Consume Model Capabilities
Xiao Hong proposed "the new Andy-Bill law": no matter how powerful the models created by model companies, application companies can consume these capabilities and transform them into user-perceivable value. This is the positioning that large model application pioneers should adopt.
This mirrors how Intel (Andy Grove) would provide more powerful chips, and Microsoft (Bill Gates) would consume that computing power with more powerful operating systems. Now, model companies provide stronger reasoning capabilities, and application companies are transforming them into intelligent agents capable of writing code, calling APIs, and planning execution.
Xiao Hong even half-jokingly offers a startup tip: "Predict what the next model capability will be, build your application around it, and wait for that model capability to launch. When that model capability improves, you'll win at the starting line you foresaw!" As an excellent product expert, he once used this strategy to succeed in his first startup.
The Agent Is Alive! The "Aha Moment" of Large Model Applications
One astounding scene from the interview is Xiao Hong describing their "aha moment" while testing the Agent in development:
They gave the Agent Manus a task to analyze how many animals appeared at a specific timestamp in a YouTube video. The Agent not only opened YouTube but also decided by its own choice to use fastfoward button to improve efficiency, precisely located the specified time, and then analyzed the screen content to provide an answer.
Xiao Hong's reaction: "You truly feel like you're creating a life."
Isn't this like a real-life prequel to "Westworld"? Except that today's Agents are still exploring the digital world, not the physical one.
"Think in Terms of Game Theory, Not Logical Reasoning"
Xiao Hong's summary of entrepreneurial thinking is insightful: don't use logical reasoning ("Baidu has the best algorithm engineers, so Baidu will definitely do recommendations well"), but instead use game theory thinking ("because a certain player joins, the entire game rules change"). Logical reasoning doesn't account for ByteDance's success (e.g. in TikTok), but game theory thinking can accommodate new players (like Liang Wenfeng for DeepSeek and Xiao Hong for Manus).
It's like chess—not simply deducing "if I make this move, my opponent will definitely make that move," but considering "because I made this move, my opponent might change their entire strategy."
With this mindset, even in a competitive environment dominated by giants, entrepreneurs can find their opportunities—not through linear extrapolation (which would only lead to the pessimistic conclusion that "everything is an opportunity for giants"), but by becoming variables that change the rules of the game.
In other words, Sam Altman's vision of top model companies crushing everything is at most only half truth. The space where models and applications each play to their strengths will likely co-exist for a long time.
Xiao Hong's Golden Quotes
In the interview, Xiao Hong offered several quotable lines worth hanging on entrepreneurs' walls:
"When you realize you're innovating and leading, you should be more aggressive, super aggressive"
"You should understand it using the most crazy imagination, better not to short it"
"Don't put application companies and model companies in opposition"
"Being yourself is most important, rather than being reactive"
Finally, facing the rapidly developing future of AI, Xiao Hong concludes by quoting Jensen Huang: "What would happen in the next few years that would surprise you?" Huang's answer was: "Basically nothing."
In other words, in the AI era, don't be too surprised by whatever crazy things happen—even if your Agent starts using fastforward key to watch YouTube videos and answer questions. After all, the awakening of agents is only just beginning!
Manus is a new AI agent developed by the Chinese startup Monica, claiming to be the world's first fully autonomous AI agent. It's designed to handle complex tasks independently after an initial user prompt, such as sorting résumés, analyzing stock trends, and generating interactive websites. Currently, Manus is in a private testing phase, accessible by invitation only.
Unveiling 2025's Hottest AI Application Form
The recent explosion of Manus claimed as the first generic agent product has brought the AI industry buzzword "agent" to the public's attention, at least effective in educating and inspiring the market. Manus's beta release demos have been impressively powerful, offering a glimpse of what agent technology can truly achieve. Whether Manus represents a genuine breakthrough or merely well-marketed hype, everyone is now curious about the emerging era of large language model agents. But what exactly is an agent?
I. From Co-pilot to Pilot: The Evolution Code of Agents
When ChatGPT exploded onto the scene, humanity realized for the first time that AI could not only answer questions but also do all kinds of knowledge tasks (translation, summarization, writing, you nam´ it) as your "cyber assistant". Early Copilot-type assistants functioned like diligent interns—obedient and responsive, answering when asked and acting when commanded. Today's Agents have evolved into "digital employees" capable of figuring out solutions to problems independently. They are no longer passive assistants waiting for instructions, but intelligent agents that can autonomously plan, break down tasks, and utilize tools.
Copilot mode: You command "write an English email," it generates text and waits for you to confirm or use it
Agent mode: You say "resolve the customer complaint within budget x," and it automatically retrieves order data → analyzes the problem → generates a solution → orders compensation gifts within budget → synchronizes the resolution record with your CRM system
This qualitative leap stems from three major technological breakthroughs:
Extended context windows: New LLMs can remember conversations of up to 1 million tokens (equivalent to an entire Harry Potter novel), building continuous working memory
Reasoning engine: Evolution from simple Chain-of-Thought to Tree-of-Thought reasoning, enabling multi-path decision making
Digital limb growth: API calls + RPA (simulating human software operation) + multimodal input/output allowing AI to truly "take action" without human intervention during the process
II. The Seven Weapons of Agents: Beyond Conversational AI
The combat power of today's top Agents comes from a "technical LEGO set" composed of seven core components:
① Search+RAG
Real-time capture of the latest information via built-in search: stock quotes, flight status, academic frontiers
Connection to enterprise knowledge bases: instant access to employee manuals, product specifications, customer profiles
Case study: A medical Agent can simultaneously retrieve the latest clinical guidelines and patient medical history during diagnosis
② Coding Capabilities
Automatically writing scripts to process Excel files
Transforming into a "digital developer" during debugging
Even developing complete applications
Impressive demonstration: During testing, a Windsurf Agent independently wrote a webpage with login/payment functionality
③ Software Operation (Computer Use)
No API interface? RPA still directly simulates human operations!
Operates browsers, Photoshop, and OA systems just like a human would
Game-changing scenario: An Agent autonomously completing the entire workflow from flight price comparison → booking → filling expense forms
④ Memory Vault (Vector Database)
Permanently remembers your work habits: "Director Wang prefers blue templates for Monday morning meeting PPTs" "Accountant Zhang's reports must retain two decimal places"
Localized storage ensures privacy and security
⑤ Multimodal Capabilities
Input and output no longer limited to text:
Converting voice meetings into visual minutes
Transforming data reports into dynamic videos
Generating mind maps while listening to podcasts
⑥ Multi-Agent Collaboration: Complex tasks tackled by "intelligent teams"
Commander Agent: Formulates battle plans
Scout Agent: Monitors data in real-time
QA Agent: Cross-validates results
Diplomatic Agent: Requests resources from humans
⑦ Planning and Reasoning
Breaking down vague instructions like "organize a product launch" into 100+ subtasks
Dynamically adjusting plans: When a venue is suddenly canceled, immediately activating Plan B
III. The Bipolar War in the Agent Universe
The agent landscape is currently witnessing a "generalist vs. specialist" showdown:
Generalist Camp
Key players: Manus, GPT-5 (? rumored to integrate all capabilities)
Advantages: Universal capabilities—coding, designing, project management all in one
Potential risks: Vulnerability to disruption by tech giants (for example, GPT-5 or DeepSeek R3 potentially crushing Manus)
Specialist CampLineup:
Medical Agents: AI doctors capable of examining CT scans, making diagnoses, and writing prescriptions
Legal Agents: Generating flawless contracts in three minutes
Financial Agents: Trading operators monitoring 37 global exchanges in real-time
Moat: Industry know-how + dedicated toolchains creating competitive barriers
IV. Hopes and Concerns in the Agent Era
On the Eve of Breakthrough:
Technical infrastructure largely in place (sufficiently long context + mature toolchain)
Multimodal large language models filling the final gaps
2025 potentially becoming the true "Year of the Agent"
Undercurrents:
Privacy concerns: Agents requiring deep access to user data
Ethical dilemmas: Who bears responsibility when an Agent books a hotel without explicit approval?
V. The Future Has Arrived: A New Paradigm of Human-Machine Collaboration
As Agents gradually master three ultimate skills:
Predictive capability: Anticipating your needs in advance ("Rain detected tomorrow, outdoor schedule modified")
Humans are finally entering an era where "the noble speaks but doesn't lift a finger"—humans set goals, while Agents handle all implementation details and solution paths. This quiet efficiency revolution shall be reshaping the rules of the game across every industry.
The only question is: Are you ready to embrace your digital colleague?
值得注意的是,随着大模型技术的发展,一些编译型框架开始在开发阶段借助 AI 提升流程设计智能化。例如企业级RPA厂商推出了“一句话生成自动化流程”的功能,由大模型根据自然语言描述自动编排RPA脚本 (link8)。这种做法本质上仍是编译型思路,只是把开发者从手工绘制流程中解放出来,让 AI 辅助完成“编译”,低代码编程了零代码。但不论流程由人编还是AI编,运行时执行的仍是固定脚本,没有运行中再规划的能力。
解释型 Agent:智能在运行时的应用
定义与特点: 解释型 Agent 指的是将 AI 的推理与决策能力融入运行环节,让 Agent 在执行过程中根据实时情况动态规划和调整行为。它不依赖预先硬编码的完整流程,而是赋予 Agent 某种程度的自主性:接受一个目标后,Agent 可以自己思考如何达成,边执行边调整策略。这类 Agent 通常由有推理能力的大型语言模型(LLM)驱动,具备自然语言理解、环境感知和自主决策能力 (link9)。它接收人类的高层指令或目标描述,能够拆解子任务、调用外部工具,循环执行“思考->行动->观察”的过程,直到完成目标 (link10)。其运行流程是解释型的:每一步都通过 AI 推理决定下一步做什么。相较编译型的刚性,解释型 Agent 具有高度的灵活性和适应性,可以处理开放式问题和动态环境。
垂直领域的集约化 vs 长尾化: 从行业生态看,Agent技术可能促使垂直领域集约和长尾需求满足两种趋势并存。一方面,行业巨头和专业厂商会将Agent思想融入各自领域,提供深度优化的垂直解决方案。例如CRM厂商可能推出智能销售Agent,结合内部客户数据和业务流程,表现远优于通用Agent。这会使各垂直领域的AI自动化更加集约,由懂行的玩家提供专业Agent服务。我们已经看到RPA厂商在金融、制造等领域构建特定场景的自动化方案,未来这些方案会纳入更多AI智能,演化成领域Agent。另一方面,大量零散的、个性化的长尾需求难以被大公司全部覆盖,比如帮个人整理特定格式的资料、处理私人化任务等。这些需求非常多样且小众,正是通用Agent大显身手的空间。一个足够通用灵活的Agent可以作为平台,让用户自行定制各种脚本,满足长尾场景。这实际上类似App Store生态,只不过应用开发者变成了Agent本身。如果Agent拥有强大的学习和适应能力,那么只要用户以自然语言描述需求,它就能胜任——这样无论多小众的需求都可以被满足,而不必等待厂商开发专门功能。因此,Agent生态很可能走向“双轨”:主流高价值场景上,大厂提供安全可靠的专用Agent功能;同时,一个开放的Agent平台生态去承接海量长尾任务,为个人和小团队提供定制智能服务。这两者并不矛盾,而且可以互补:通用Agent平台培养起来的创新点子,反过来也许会被验证后垂直化商业化。对于开发者而言,需要关注哪些接口和能力值得投入构建,以及如何在专用与通用之间找到平衡。既要利用好万能接口快速覆盖功能,又要在可能的情况下打通更底层的专用接口,提高Agent服务的不可替代性。
随着技术的发展,二者的界限正在变得模糊,一种兼具编译型的可靠性与解释型的灵活性的混合架构正在形成。这种混合架构不仅反映了技术的自然演化,也代表了解决实际问题的更实用方法。通过在系统的不同层次和功能点上有机集成确定性和 best practice,混合架构Agent能够在确保核心功能可靠性的同时,灵活应对变化和不确定性。
目前常见的工具类型包括:搜索引擎(用于信息检索)、知识库/RAG检索(基于向量数据库查资料)、浏览器(访问网页)、编程解释器(执行计算和代码逻辑)等 (Introduction to LLM Agents | NVIDIA Technical Blog)。一些 Agent 框架还结合了传统的RPA(机器人流程自动化)技术,使LLM能够控制鼠标键盘去操作应用界面,实现如自动表单填写、跨系统数据搬移等复杂操作流程。需要注意的是,在调用工具时,Agent 必须先通过决策模块判断何时需要工具以及选择何种工具,这通常由LLM根据当前任务状态和预设的工具列表自主决定 (Agents | Mistral AI Large Language Models)。因此,工具使用能力依赖于LLM对自身能力边界的“自知”,知道何时该借助外力。总体而言,让Agent学会用工具,就像教会AI使用人类的双手和眼睛,它是实现从语言到行动的桥梁,也是当前Agent技术最具实用价值的方面之一。
OpenAI(GPT-4 Turbo):作为引爆本轮热潮的OpenAI,在Agent方面的布局主要体现在为其通用模型赋能工具使用和多模态能力上。GPT-4 Turbo 是 OpenAI 在 2024 年底推出的改进版模型,不仅大幅扩充了上下文窗口,还原生支持图像输入和语音输出,实现真正意义上的多模态 (OpenAI Announce GPT-4 Turbo With Vision: What We Know So Far)。更重要的是,OpenAI为GPT系列模型引入了函数调用和插件机制,使ChatGPT从一个纯语言对话助手升级为具备Agent雏形的系统。借助函数调用,开发者可以预先定义工具接口,让GPT在回答问题时自动调用这些工具,获取实时结果再返回给用户。这一能力已经在ChatGPT插件中得到验证,例如Browsing插件让GPT能上网搜索,Code Interpreter插件让其能运行代码并返回结果。OpenAI官方将这套能力称为“扩展GPT的眼界和手脚”,使其可以访问外部信息源并执行操作 (Introduction to LLM Agents | NVIDIA Technical Blog)。可以说,OpenAI 正在把ChatGPT由一个静态问答模型,转变为一个可执行复杂任务的平台型智能代理。
目前,GPT-4 已被广泛用于开发各种自主代理实验,如开源的 Auto-GPT 就是基于 GPT-4 API 实现,让 AI 连续自主执行用户给定目标的一系列操作。这些探索也反过来推动OpenAI不断改进其模型的可靠性和自主决策能力。因此,OpenAI 在Agent领域的显著特点是:以通用大模型为核心,通过插件和API扩展实现代理功能,并逐步增强模型的推理和多模态表现,为各行业构建AI代理打下基础。OpenAI 最新的智能体表现是基于其推理模型o3的 Deep Research 功能,可以就任何题目自动搜寻资料、研读并汇总融合成全面完整、信息可追溯的综述性调查报告。(本文就是 o3 deep research 完成。)
作为开源力量的代表,Mistral AI 正把尖端的LLM能力平民化,让各行业的团队都能“掌控未来”,将大模型部署在自己的环境中 (Mistral AI | Frontier AI in your hands)。其背后的趋势是:开源高效模型 + 易用代理开发平台,为垂直领域AI代理的诞生提供了肥沃土壤。这也为大模型生态引入更多创新和竞争,促进整个Agent技术的成熟。
时至 2025 年,相关技术组件如LLM、工具接口、多智能体架构等日趋成熟,已经为孕育“爆款”级别的Agent产品奠定了基础。可以预见,各行业将很快出现能够大幅提升生产力的AI代理,从而推动业务模式的革新与效率飞跃。当然,我们也应保持理性,关注Agent技术带来的新挑战,如可靠性、安全性和伦理风险,并在技术演进中逐步建立规范和治理。然而,展望未来,LLM生态与Agent技术的融合前景令人振奋——一个人机共生、多智能体协作的时代或将加速到来。正如业内分析所言,随着技术的演进,智能代理的应用范围几乎是“无限且不断扩张”的,人类将持续发现新的方式将其融入工作和生活 (Applications of LLM Agents in various industries)。我们有理由相信,LLM 驱动的 Agent 将在未来几年释放出更大的潜能,成为数字时代不可或缺的基础设施和创新源泉,值得所有AI技术爱好者和从业者持续关注和投入。
推理模型是当前生成式AI的主流热点,带火了一个热词(buzz word)叫 test time compute,咱们就先从它谈起。
从模型开发者视角,test time(测试时间) 针对的是 training time (训练时间)。众所周知,这是机器学习的两个阶段,一个是在线,一个是离线。训练模型好比是软件开发;测试模型就是软件测试。模型测试阶段就是常说的(在线)推理(inference)阶段,所以 test time 又叫 inference time。
test time compute 之所以流行,是因为大模型领域近几个月的“范式转变”。社区依据预训练scaling law原来一直聚焦基座大模型的做大做强,但发现大算力带来大智能的效益递减,进入了平台期。于是把重心转移到后训练的强化学习,发展了一种称为 System 2 慢思维模式的推理模型。这种推理模型最大的特点就是运行起来慢了,原来的秒回现在是慢了几拍才回复,消耗了更多在线时间和在线推断的算力(即 test/inference time compute)。
模型训练阶段,无论是预训练还是后训练,都是离线进行的,迭代循环,在改变模型的参数,模型并未成形,属于开发进行时。而 test time 说的是模型已经完成阶段。严格说,test time 是内部试运行阶段,让 QA(quality assurance)部门在上线发布前做测试。但现在谈 test time compute,已经不分内部测试还是用户使用,所以更准确的术语还是 inference time compute。
其实,inference time 口语中也叫 running time 或 runtime,其他的近义词和关联词还有很多: test-time,real time,decoding time, prediction time, service time, execution time, on-the-fly computing time ...
在人工智能发展的历史长河中,符号逻辑和神经网络一直如两条平行线,难以交汇。然而,2025年春节,DeepSeek发布的推理大模型R1揭示了一个令人惊叹的技术突破——思维链(Chain of Thought, CoT)的自主生成,其展现出的语言序列仿佛在模拟人类的符号逻辑。这一强化学习的进展或将重新定义符号逻辑与神经网络的融合方向。
Mr. Huang's background features three S-curves, illustrating the scaling relay race across three stages of large language models, demonstrating a persistent spirit akin to the Chinese fable of the legendary Old Man Who Moved Mountains.
We know that large language models have three stages: pre-training, post-training, and online inference. The biggest change in recent months is the community consensus, following Ilya Sutskever's claim, that the pre-training era has ended. The famous empirical scaling laws for pre-training appear to have plateaued. This has led to the rise of inference models (OpenAI's O series and Deepseek's R series, among others), which emphasize investment in chain-of-thought (CoT) reinforcement learning during post-training and utilization of online inference time (so-called "test time compute"). These reasoning models have indeed demonstrated unprecedented achievements in mathematics, coding, and creative writing.
The scaling of post-training for reasoning models has just begun, and it's unclear how far it can go. But we can gradually see this trajectory from O1 evolving to O3, and from R1 to the reportedly soon-to-be-released R2 and their enhanced capabilities. What about the test time scaling in the final inference stage?
Recently, I spoke with my old friend Junlin, one of the earliest advocates for the three S-curves of scaling in China. I mentioned that I hadn't seen any real test time scaling because no one can control the model's test time compute—how much time/computing power it uses and when it completes assigned tasks is determined by the model itself, so test time doesn't seem "scalable." Junlin agreed that this is currently the case.
These past few days, while playing with large models' deep research capabilities, I've gradually experienced some possibilities for test time scaling. The answer is emerging. Fundamentally, it's about whether there's a curve showing that if you give a query or topic more thinking and response time, it performs better. Specifically, with O3-mini, there's a button called "deep research" that users can choose to use or not to use. Without it, your question still follows a chain of thought because you initially selected the reinforced O3 reasoning model. The process for reasoning models typically takes a minute or two. However, if you also press the deep research button, the final reasoning time is extended by several times, potentially lasting up to 10 minutes. This shows us that even with the same model, different inference times produce different results. This should count as a precursor of test time scaling.
How does it work? How can users invest different amounts of test time compute based on the difficulty or challenge of their topic and their tolerance for waiting time to generate different results for the same topic? It turns out it uses an agent-like approach. The functionality provided by the deep research button is essentially a research reasoning agent. Agents are an additional LLM-native feature that doesn't require changing the model—it changes the interaction method during the inference stage. Currently, this interaction is very simple, just one round, but this test time scaling direction is expected to continue exploring longer and more interactions with users to help maximize the effect of test time compute.
If test time compute scaling doesn't quickly hit bottlenecks, we can imagine future deep research interacting with users for extended periods to complete highly complex projects. Perhaps we're moving beyond minute-level reasoning time investments—we can entirely envision large models investing hours or even days to complete challenging tasks, such as projects that would take human researchers months or years, or completing research projects humans cannot accomplish. The current deep research is very simple—after receiving the user's prompt/query, it immediately breaks down the problem and asks the user five or six simple questions to confirm the required sources, breadth, depth, and considerations for the research. After receiving user feedback, the model begins accepting updated materials (if any) and uses search to collect more relevant information. Then, following the decomposed tasks and the plan confirmed with the user, it analyzes each source and finally synthesizes everything into a research report. This naturally extends the required reasoning time because the task is no longer singular, and the materials aren't limited to knowledge already digested within the model but include more sources searched in real-time—processing all this takes time.
For both reinforcement learning in the post-training stage of reasoning models and the investment in test time compute during the inference stage, the scaling journey has just begun. Let's hope these two S-curves can continue to rise steadily for some time, allowing the scaling relay race to help us progress continuously on the path toward artificial general intelligence (AGI) and eventually artificial superintelligence (ASI).
我们知道,大模型有三个阶段:预训练、后训练、在线推理。过去几个月最大的改变是,业内基本有了共识,就是伊利亚宣称的说法,预训练时代结束了,著名的预训练的 scaling law 的经验法则貌似走到了头,进入平台期。于是有了推理模型(OpenAI O 系列,以及deepseek R 系列等)的兴起,强调的是后训练的思维链强化学习的投入以及对于在线推理时间(所谓 test time compute)的利用。推理模型也确实在数学、代码以及文字创造性方面展现了前所未有的亮眼成绩。
推理模型的后训练 scaling 刚开始,能走多远,还不清晰。但这个轨迹可以从 o1 变成 o3,以及 r1 到据说今后一两个月随时可能发布的 r2 等能力增强上,慢慢看到。最后这个推理阶段的 test time scaling 呢?
前阵子我跟国内最早鼓吹 scaling 三条S曲线的老友 Junlin 说,根本就没看到什么 test time scaling 呀,因为用户不能掌控模型的 test time compute,它花多少时间/算力,啥时候完成我给它的指令任务,是大模型自己决定的,test time 并不是可以“伸缩”(scaling)的呢。Junlin说,目前确实如此。
这几天玩大模型 deep research,逐渐体会到一点 test time scaling 的伸缩可能性。答案的端倪出现了。说到底就是,如果一个query 或课题,有没有一条曲线表示,如果你给它更多的思考和响应时间,它就完成得更好。具体说,在 o3-mini 下,有一个 button 叫 deep research,用户可以选择用或者不用。如果不用,你的问题也会有思维链,因为你一开始就选择了已经后训练强化的 o3 推理模型。推理模型的思维过程通常是一两分钟吧。但是如果你同时又按下 deep research 按钮,它最终完成任务的推理时间是加n倍的等待时间,可以长达10来分钟。这至少让我们看到了,模型不变,但推理现场的缩放时间不同,其结果是不同的。这应该算是 test time scaling 的前序或影子了。
那它是怎么做到的呢?让用户可以根据自己的课题的难易或挑战性,以及自己可以容忍的等待时间,来对同一个课题做不同的 test time compute 的投入,以便生成不同的结果呢?原来,它用的是某种 agent 的思路。deep research 这个按钮所提供的功能,实际上就是一个研究性推理的 agent。agent 是 LLM-native 的附加 feature,但不需要改变模型,它所改变的是在推理阶段与用户的交互方式。目前这种交互非常简单,只有一轮,但所开辟的这个 test time scaling 方向,预计可以继续探索与用户更长更多的交互,来帮助最大化 test time compute 的效果。
如果 test time compute scaling 并不是很快就遇到瓶颈,可以想象将来的 deep research 可以与用户互动很长的时间去完成一个非常复杂的项目,也许不是分钟量级的推理时间投入了,完全可以想象大模型投入 hours 甚至 days 来完成一个高难课题,譬如一个人类研究员需要几个月甚至几年才能完成的项目,或者完成一个人类无法完成的研究项目。当前的 deep research 非常简单,它在得到用户的 prompt/query 后,立即分解问题,并反问用户五六个简单的问题,来确认这个研究所需要的资料来源、广度、深度以及注意事项。得到用户的反馈以后,模型开始接受用户更新的资料(if any),并用 search 来收集更多的相关资料,然后按照任务的分解以及与用户确认过的计划和信息,对于每一个来源做分析,最后综合贯通,形成研究报告。这样一来,它所需要耗费的推理时间自然就加长了,因为任务不再是单一的任务,资料也不仅仅是自己模型内部已经消化了的知识,而是现场搜索的更多来源,处理这一切都需要时间。
对于推理模型的后编辑阶段的强化学习以及它在推理阶段的 test time compute 的投入,这两阶段的 scaling 征程刚刚开始。希望这两条S曲线还可以稳定上升一段时间,让 scaling 的接力赛助力我们在通用智能(AGI)和超级智能(ASI)的道路上不断前行。
In today's rapidly evolving artificial intelligence landscape, deep learning models have become the core engine driving technological innovation. However, behind these impressive achievements, deep learning faces several fundamental limitations that are not merely technical implementation challenges but are determined by the essence of its methodological approach.
This article explores the core limitations of deep learning beyond the well-known "black box" problem and analyzes their mathematical origins.
I. "Original Sin" of Data-Driven Approaches: Philosophical Dilemma of Statistical Learning
Confusion Between Correlation and Causation
Deep learning models are essentially high-dimensional probability density estimators. Their core objective is to find the best approximation of the conditional probability distribution P(y|x;θ) through parameters θ. Models learn from large volumes of training data, attempting to capture statistical patterns of various sizes and generalize them to unknown data. However, this statistical learning paradigm leads to a fundamental problem: models learn P(y|x) rather than P(x→y) – statistical correlation rather than causal relationships.
Consider a simple example: an AI medical system might discover that a certain type of rash is highly correlated with malaria diagnoses (possibly because the data was collected in regions with mosquito proliferation issues). The model establishes a pseudo-causal relationship of "rash → malaria" while overlooking temperature, humidity, and other actual disease factors.
This "causal misplacement" leads to poor model performance in new environments:
In regions without mosquito problems, the model may over-diagnose malaria
When facing new infectious diseases, the model may misclassify them as known categories
When the diagnostic environment changes, model performance significantly deteriorates
Information Bottleneck and Compression Distortion
According to information bottleneck theory, neural networks need to perform a special kind of information compression during training: discarding information in input X that is irrelevant to prediction Y while preserving all relevant information. Mathematically, this is expressed as maximizing:
I(Z;Y) - β·I(X;Z)
Where Z is the intermediate representation, I denotes mutual information, and β is a trade-off coefficient.
When training data is insufficient or biased, this compression process encounters serious problems:
Discarding genuine causal signals (e.g., cell morphological features in medical images)
Preserving pseudo-correlative signals (e.g., using hospital wall colors as diagnostic criteria)
The essence of this "lossy compression" causes models to grasp incorrect features in new environments. In fact, when H(Y|X) is incorrectly minimized, the model establishes data defect-driven false information channels rather than accurate mappings of reality.
II. The Low-Dimensional Manifold Hypothesis for Natural Data
A classic assumption in machine learning theory is that natural data resides on low-dimensional manifolds within high-dimensional spaces. Taking a simple example of a two-dimensional manifold in three-dimensional space, it resembles folded paper – although data points exist in 3D space, the intrinsic structure is 2D. Manifolds possess local Euclidean properties of smoothness and continuity: the neighborhood of any point on the manifold can be mapped to a low-dimensional Euclidean space. For instance, when a face rotates, the image slides continuously on the manifold without sudden changes.
Basic Concepts
High-dimensional space: Refers to mathematical spaces with dimensions far greater than 3. For example, a 100x100 pixel image exists in a 10,000-dimensional space (each pixel being one dimension).
Low-dimensional manifold: A continuous, smooth low-dimensional structure embedded in high-dimensional space. For example, a two-dimensional surface in three-dimensional space, or a structure of dozens of dimensions in a space of millions of dimensions. For instance, all ways of writing the digit "2" in a 784-dimensional pixel space form an approximately 10-dimensional manifold (controlling stroke thickness, tilt, curvature, etc.).
Why Natural Data Forms Low-Dimensional Manifolds
Natural data (such as video, images, audio, text) may seem to contain high-dimensional features but is constrained by physical laws and semantic restrictions, exhibiting low-dimensional characteristics:
Physical constraints:
A facial photograph's parameters are limited by bone structure, lighting angle, facial muscle movements, etc., with actual degrees of freedom potentially fewer than 50 dimensions.
Semantic constraints:
In textual data, grammatical rules and semantic coherence restrict seemingly unlimited vocabulary combinations to a finite meaning space. Other modal data is similar, also constrained by relationships between atomic units (tokens).
Dimensionality Reduction and Feature Extraction
The information "compression" in models is actually a process of dimensionality reduction and feature extraction. For example, the hierarchical structure of Convolutional Neural Networks (CNNs) progressively strips away redundant dimensions, approaching the essence of data manifolds. Shallow layers extract edges (local linear structures), while deeper layers combine them into object parts (global manifold structures). Manifold Learning explicitly recovers the intrinsic low-dimensional structure of data.
Taking 3D object recognition as an example: The translation and rotation of objects in 3D space form a 6-dimensional manifold (3 translations + 3 rotations). When related video image data is embedded in high-dimensional pixel space, ideal 3D object recognition involves dimensionality reduction to its 6-dimensional manifold, identifying objects through feature extraction.
III. Adversarial Examples: Fragility at Distribution Boundaries
Adversarial examples refer to samples that, through minor perturbations to original input samples, can cause deep learning models to produce incorrect outputs. For instance, a slightly modified panda image might be identified as a turtle with 99% confidence by AI.
The existence of adversarial examples reveals structural defects in data manifolds, challenging the traditional manifold hypothesis discussed above and exposing its fragility:
Natural data manifolds contain numerous "holes": areas not covered by training data
Manifold boundaries have high-curvature regions: minor perturbations can cross category boundaries
Theoretically, the possible combinations of high-resolution color images far exceed astronomical numbers. While natural images are constrained by physical laws, substantially reducing the effective space, it remains far from being adequately covered by existing datasets. This data sparsity is one fundamental reason why deep learning models are susceptible to adversarial attacks and struggle to generalize to extreme scenarios.
This sparse coverage allows attackers to find vulnerable points near decision boundaries. For example, adding carefully designed noise to a panda image that is almost imperceptible to the human eye can cause an image recognition model to misclassify it as a turtle.
Adversarial examples are not random but systematically exploit the geometric structure of model decision boundaries. A panda image being identified as a turtle is not due to random noise but because the noise is precisely added in the direction of the shortest path to the decision boundary.
Failure of Lipschitz Continuity
Lipschitz continuity is a metric for measuring how sensitive a function is to input changes. The higher the Lipschitz constant (L-value) of a deep network, the more sensitive the model is to input perturbations. The L-value of actual deep networks in adversarial directions can reach 10^3 magnitude, meaning that even minor perturbations may cause dramatic changes in model output. For example, in an autonomous driving system, if the image recognition model is overly sensitive to input perturbations, it might misidentify a large truck crossing an intersection as sky, leading to incorrect driving decisions.
Ideal classification models should satisfy the Lipschitz continuity condition, meaning that minimal input changes should only lead to limited output changes:
‖f(x+δ)-f(x)‖ ≤ L‖δ‖
Mathematical expression meaning:
‖model(input+small change) - model(input)‖ ≤ L × ‖small change‖
L is the "sensitivity coefficient," smaller L is better.
The failure of Lipschitz continuity causes input space to exhibit strong anisotropy (i.e., sensitivity in different directions varies dramatically). Imagine standing in complex terrain:
Natural perturbation directions (L≈1): Like walking on a gentle slope, moving 1 meter changes elevation by 1 meter, movement is safe and controllable
Adversarial perturbation directions (L≫1, e.g., L=10³): Like standing at a cliff edge, moving 1 centimeter might result in a 100-meter fall
This geometric structure makes it difficult for data augmentation based on uniform sampling to cover high-risk areas, as these areas have extremely low probability in natural data distribution but are "close" in Euclidean distance. For example:
Natural direction: Not sensitive to perturbations like lighting changes, blur, etc. (L≈1) ➔ Model can correctly handle everyday image variations
Adversarial direction: Specific minor perturbations cause dramatic changes (L=10³) ➔ Like applying "magic noise" to images, causing model misclassification
The Danger:
Exploited by attackers: Finding high-L directions to create adversarial examples is like knowing cliff locations and specifically targeting vulnerable points
Difficult to defend: Regular training covering all directions is prohibitively expensive, like requiring hikers to adapt to all terrain types, which is unrealistic
IV. The Mathematical Chasm Between Interpolation and Extrapolation
Interpolation Success vs. Extrapolation Failure
Deep learning models perform excellently on interpolation tasks but often fail in extrapolation tasks. This is not coincidental but determined by the essence of statistical learning:
Interpolation: Predicting points within the support set of the training data distribution, equivalent to filling gaps in known regions
Extrapolation: Predicting points outside the support set of the training data distribution, equivalent to exploring unknown regions
The success of modern deep learning largely depends on the assumption that "training distribution ≈ testing distribution." When this assumption is broken, extrapolation problems become severe, and model performance deteriorates dramatically.
Differential Geometric Explanation of Extrapolation Failure
Imagine you are a geographer drawing terrain maps:
Input space (M): The entire Earth's surface, containing plains, mountains, canyons, and various terrains
Data distribution (P_data): Regions explored by humans (cities, roads, farmland, etc.)
Classification model (f): Maps drawn based on terrain features (marking where forests, deserts are)
Decision boundaries: Transition zones between different terrains (e.g., transition between forest and grassland)
Tangent Space: Trends in terrain changes in explored areas. For example, in plains, slopes are gentle in east, west, north, and south directions (corresponding to natural perturbation directions).
The normal bundle refers to directions perpendicular to explored areas, such as suddenly appearing cliffs.
Key problem: Maps are accurate in explored regions but fail in unknown cliff areas.
When moving in unknown cliff areas, test data falls in the normal bundle of the training data distribution, and model generalization performance drops dramatically. This situation can be characterized by the following inequality:
Where κ is the curvature radius of the decision boundary, comparable to the width of the transition zone between forest and grassland on the map; δ is the perturbation vector, i.e., the direction of movement.
∇ₓ log P_data(x): "Terrain steepness" of data distribution
In frequently visited human areas (like cities), terrain is gentle (small gradient)
In uninhabited areas (like deep sea), terrain is steep (large gradient)
It is impossible to effectively cover unknown cliff areas through conventional training data augmentation because they have extremely low probability in the training distribution. Conventional data augmentation is like exploring in known areas and will not actively explore cliff directions because (1) the probability is extremely low: normal people don't deliberately jump off cliffs; (2) the cost is prohibitively high: exploring all dangerous directions requires infinite resources.
Consequence: When map users accidentally walk to the edge of a cliff, the navigation provided by the map fails; the map cannot predict whether you will fall off the cliff or discover a new continent.
Beyond Data-Driven Artificial Intelligence
The limitations of deep learning are not temporary technical difficulties but methodological boundaries determined by its "data-driven" nature. Relying solely on statistical patterns in data makes it difficult to achieve true causal understanding, out-of-distribution generalization, and reliable security guarantees.
One future direction may be to combine data-driven learning with structured prior logical symbolic systems, creating hybrid systems that can both leverage massive data and possess causal reasoning capabilities.
李普希茨连续性是衡量函数对输入变化敏感程度的一个指标。深度网络的李普希茨常数(L值)越大,表示模型对输入的扰动越敏感。实际深度网络的 L 值在对抗方向上可达 10^3量级,这意味着即使微小的扰动也可能导致模型输出发生剧烈变化。例如,自动驾驶系统中的图像识别模型如果对输入的扰动过于敏感,就可能将前方横穿路口的大卡车误识别为天空,从而导致错误的驾驶决策。
理想的分类模型应满足李普希茨连续条件,即输入的微小变化只能导致输出的有限变化:
‖f(x+δ)-f(x)‖ ≤ L‖δ‖
数学表达含义:‖模型(输入+小改动) - 模型(输入)‖ ≤ L × ‖小改动‖
L是"敏感系数",L越小越好。
信息瓶颈理论的启示:信息瓶颈理论认为,一个好的模型应当在保持对输出预测有用信息的同时压缩无关的输入信息。在深度学习中,隐藏层可以被看作输入信息到输出信息的“瓶颈”。研究发现,深度神经网络的训练过程可能包含两个阶段:先是拟合训练数据,尽可能记住输入细节;随后进入压缩阶段,有意或无意地丢弃与输出无关的冗余信息 (Anatomize Deep Learning with Information Theory | Lil'Log)。这种压缩有助于提升泛化能力,因为模型专注于关键信息而忽略噪声。信息瓶颈观点为泛化提供了理论解释:模型最终学到的是关于输出的充分简洁表示,而非输入的完整细节。如果一个模型无法有效压缩信息,仍记忆了大量与任务无关的细节,它在新样本上表现往往较差。这一定程度上解释了为何适当的正则化和表示压缩有利于泛化。
理想情况下,分类函数应该是足够平滑的,对输入的小扰动保持稳定。然而,深度神经网络通常缺乏全局的李普希茨连续性约束,其输出对输入变化非常敏感。当网络在训练数据上高度拟合时,在某些方向的梯度会变得很大。这意味着存在较大的局部李普希茨常数——输入的一微小变化可以引起输出置信度的巨大变化,从而跨越决策边界。研究已表明,仅修改图像的几个像素就可能导致DNN完全错误地分类,这强调了此类模型局部稳定性的缺失 (Frontiers | Multivariate Lipschitz Analysis of the Stability of Neural Networks)。形式上,如果一个模型$f(x)$的李普希茨常数$L$非常大,那么$|x'-x|$虽很小,但$|f(x')-f(x)|$可能超过判别阈值,导致类别变化。对抗样本正是利用了这一点:通过沿着梯度方向施加精心设计的微小扰动,攻击者使模型输出发生非线性放大,从而产生错误分类。直观来说,深度网络在输入空间形成了复杂的山谷和峰峦,对抗扰动就像在谷底推了一把,看似平静的输出瞬间跃上海拔。稳定性与精确拟合间存在矛盾:理论和实证结果都指出,提高模型对对抗扰动的鲁棒性常常要以牺牲部分标准精度为代价 (Frontiers | Multivariate Lipschitz Analysis of the Stability of Neural Networks)。这被视为深度学习中的一种基本权衡:追求对训练数据的极致拟合(高精度)会导致决策函数过于陡峭,从而难以兼顾对输入噪声的稳定性。这种李普希茨连续性的失效解释了为何神经网络在非常局部的范围内缺乏鲁棒性,也指导我们通过控制梯度范数(例如谱范数约束)来提升模型稳健性。
3.3 微分几何视角:测地线攻击路径与决策边界曲率
从微分几何的角度,可以将输入空间视为带有测度的流形,分类决策边界则是嵌入其中的一个超曲面。测地线攻击路径指的是在输入空间中,连接原始样本与目标对抗样本的最短路径。如果模型足够鲁棒,那么在原始类别流形内沿任意短路径都不应越界;但实际情况是,攻击者可以找到一条极短的路径穿过决策边界,将样本送入错误类别。这条路径往往偏离数据流形,抄近道绕过了模型对流形内数据的防御。决策边界的曲率在其中扮演重要角色:如果边界在样本附近高度弯曲或复杂起伏,那么存在局部区域使得很小的扰动即可达到另一侧类别。研究发现,通过对抗训练等方法增强鲁棒性,会显著降低决策边界在输入空间的曲率,使其更加平滑 ([PDF] Robustness via Curvature Regularization, and Vice Versa)。也就是说,脆弱模型的决策边界可能是“皱巴巴”的,充满高曲率的小曲面,导致分类区域犬牙交错;而鲁棒模型的边界更趋于平滑和笔直,需要更大的扰动才能跨越 ([PDF] Robustness via Curvature Regularization, and Vice Versa)。在微分几何上,可以将对抗扰动视作在决策边界法向方向上的微小位移。对抗攻击等价于找到一条绕过边界的捷径,而边界曲率越大,这条捷径越短。比如,当决策边界在样本点附近形成一个凸起,攻击者沿垂直于边界方向前进一点点就跌下凸起进入另一侧分类区域。这解释了测地线极短且几乎贴着数据流形表面的攻击路径是如何存在的。此外,高曲率还意味着不同方向上的鲁棒性各异,模型在某些特征方向上特别脆弱。综合来看,微分几何视角揭示:深度模型决策边界的形状不够平滑规整,存在曲率过大的薄弱环节,这使得对抗样本能够以最小的“能量”越过边界成功欺骗模型。
鲁棒优化:从优化的角度,将训练目标改为极小极大问题,提升模型在最坏情况下的性能。这与对抗训练本质相同,即在损失函数中加入对扰动的最大化过程,寻找模型决策在局部的最坏情况并据此更新参数。一些改进的方法如PGD(投影梯度下降)对抗训练、TRADES等,都属于鲁棒优化范畴。它们通过更强的攻击迭代或修改损失项来提高鲁棒性。然而,这类方法经常面临计算成本高昂的问题,而且当扰动范围增加或攻击方式改变时,模型鲁棒性可能急剧下降 (Adversarial Attack and Defense: A Survey)。鲁棒优化也难以防御分布外或物理世界中的攻击(如真实场景的光线变化、打印再拍摄攻击),因为这些超出了简单范畴内扰动的假设。
数据缺陷的量化表达:对于深度模型因数据导致的泛化问题,有学者借鉴物理概念提出了类似**“正交灾难”和“不确定性原理”的观点加以描述。正交灾难指的是在高维空间中,不同样本或特征方向往往近似正交,导致模型难以在各方向上同时保持良好性能——在一个方向上精细拟合数据(降低误差),可能会牺牲在另一个正交方向上的泛化,从而陷入维度灾难的困境。这可以类比于量子多体系统中的正交性灾难:状态空间维度巨大,以致一个微小扰动就使系统基态与原本几乎正交,重叠率骤降。对应到深度学习,微小的分布变化可能令原模型与新形态的“真实函数”几乎无重叠,需要完全重新学习,这解释了模型对分布变化如此敏感的原因。同时,不确定性原理被用来类比深度模型中精度与鲁棒性**的不可同时最大化 (On The Uncertainty Principle of Neural Networks)。有研究提出,网络对输入的识别能力和对扰动的抗噪能力是一对互相制约的“共轭变量” (On The Uncertainty Principle of Neural Networks)——提高对特征的敏感度(提升精度)会降低对梯度扰动的鲁棒性,反之亦然 (On The Uncertainty Principle of Neural Networks)。这种观点将深度学习的权衡提升到原理层面,提示我们在设计模型时必须接受某种形式的折衷,如同测不准原理限制同时精确测定粒子的位置和动量一样。对这些现象的量化分析,能够加深我们对模型固有局限的理论理解,为突破现有瓶颈提供指引。
