In his blog post^{[1]</sup>, Alex points out that it is impolite to present AI-generated content to others without personal filtering and reflection. AI content forwarded without thought is like a "virus" or "slop", which he believes wastes the recipient's time and energy. Therefore, he advocates for a new "AI etiquette": AI-generated content should only be shared if the sharer has adopted it, is willing to take responsibility for its output, or if the recipient has explicitly consented.</p>} The "Measures for the Management of Generative Artificial Intelligence Services", effective September 1, 2025, issued by the Cyberspace Administration of China^{[2]</sup>, is, in a sense, at the center of this topic's vortex.</p>} A century ago, the scarcity and closure of information were the primary obstacles to cognition. But today, it is information overload.</strong></p> I do not intend to deliberately deepen this issue, but it is indeed a philosophical speculation on the nature of information, creative ethics, and human dignity.</p> </a> There is Nothing in the Human Mind That AI Cannot Replicate</h2> "There is nothing in the human mind that AI cannot replicate, and AI already possesses subjective experience." — 2024 AI for Good, Geoffrey Hinton^{[3]</sup></p> </blockquote>}I agree with this viewpoint. (See When Boundaries Disappear</a>)</p> Of course, this is not a view one needs to take a side on right now, much like believing in aliens, it is purely based on personal intuition^{[4]</sup>. This serves as the backdrop for discussing AI Generated vs. Human Made, shifting our focus and discussion to "What kind of information is valuable?"</strong> rather than whether it's generated by AI or made by humans, regardless of the level of AI that generated it. In this sense, there is no difference between content generated by AI and by another person.</p>} Let's first talk about "value", which you can also roughly understand as "meaning."</p> </a> What is So-Called "Value"</h2> </a> Three Perspectives on Value</h3> Objectivist Perspective: Value as a Property</strong></p> Plato believed in the "Good" existing in the world of Forms; value is an inherent property of things. The beauty of a flower, the justice of an act, the truth of an argument—their value exists independently of the observer. So, if an unread article still has value, where does its value reside?</p> </li> Subjectivist Perspective: Value as a Projection</strong></p> Nietzsche declared, "There are no facts, only interpretations." Value is not discovered but created. It is humans who project meaning onto an originally neutral world. If value is purely subjective, does "universal value" still have meaning?</p> </li> Relational Perspective: Value as an Emergence</strong></p> I believe more people, like myself, tend to think that value is neither entirely objective nor purely subjective, but emerges in relationships.</strong> It exists in the encounter between a subject and an object; the value of my article is realized the moment a reader reads it. It exists in the relationship between demand and supply; my article is more valuable to an AI practitioner than to someone uninterested in the topic. It also exists in the intersection of time and space; this same article has different values at different moments.</p> </li> </ul> I wonder if you've sensed that, regardless of the perspective, "purpose" looms as a standard for judging value, be it a subjective personal need or an objective destination for humanity.</p> </a> The Nihilistic Trap of Value</h3> Kant argued that only "persons" have intrinsic value (dignity), while everything else merely has a price. Buddhism, on the other hand, posits that even the "self" is an illusion, so how can we speak of intrinsic value? This is the definitional nihilism of value. If we continue to ask: where does the value of the standard for judging value itself come from? This infinite recursion is the boundary nihilism of value (it may well be the boundary of human reason). I don't want to fall into this deconstructionist trap of "why of why of why..." but rather to stop at a certain "why." This is part of what I mean by the "experiencer."</p> Wittgenstein said, "My propositions serve as elucidations in the following way: anyone who understands me eventually recognizes them as nonsensical, when he has used them—as steps—to climb up beyond them. He must, so to speak, throw away the ladder after he has climbed up it." The recursive nature of value is like this ladder—its meaning lies not in endlessly questioning, but in making us realize that:</p> At some point, we must stop asking "why" and start acknowledging "it just is."</p> </blockquote> To start acknowledging "it just is" is the formation of the "self".</strong> Like axioms in mathematics that require no further proof, it means your value system has foundational beliefs—biological, social, individual, and even transcendent.</p> </a> The Three Elements of Value</h3> Returning to the question, "What kind of information is valuable?" I believe that information worth our reading should possess at least one or more of the following characteristics:</p> Intellectual Increment:</strong> Does it offer a unique perspective, profound insight, or high-quality integration? The value of information lies in reducing uncertainty. If AI-generated content is merely a repetition, patchwork, and paraphrase of existing knowledge, it is "information entropy" garbage. Truly valuable content is when humans use AI as a lever for their thinking to pry open new frontiers of knowledge. The core of this lies in the intellectual height of the questioner, not the generative capability of the AI.</p> </li> Utility Condensation:</strong> Does it save me a significant amount of time and energy? For example, a high-quality research report assisted by AI, which distills hundreds of financial reports and news articles into a few pages of conclusions and charts. Here, the AI is not the original creator of the content but an extension of the human expert's will, a powerful "information compressor." What we consume is not the AI's words, but the time, experience, and judgment of the expert behind them.</p> </li> Contract of Accountability:</strong> Is the publisher of the content willing to back it with their own reputation? Regardless of how the content is generated, once published, the publisher establishes an implicit contract with the consumer. The publisher promises that they have completed the work of filtering, verifying, and refining for us, and that this content is worth our time. This act of collateralizing personal or institutional credibility is key to distinguishing a "creator" from a "slacker."</p> </li> </ul> </a> Value Reconstruction in the AI Era</h2> </a> The Imbalance of Labor and Value</h3> Traditional creation follows an implicit social contract: the creator invests time and effort (referring only to thoughtful investment), and the reader repays with attention and recognition. This equivalence of time constitutes the basic dignity of information exchange. A meticulously written novel, a well-thought-out code pull request, a rigorous academic paper—their value is partly derived from the "time cost" invested by the creator.</p> AI shatters this balance. When the cost of labor approaches zero, we naturally feel the sense of rejection mentioned at the beginning, while subjectively ignoring whether it has value. When AI can generate content infinitely, it is in effect making finite human attention consume infinite machine output. This leads to efficiency and ethical questions: Do we have the right to use low-cost generation to consume the high-cost lives of others? This may eventually evolve into a debate on how silicon-based and carbon-based life can coexist. Furthermore, besides the result, human creation has another crucial dimension—the meaning of the process itself.</strong> The evolution of thought during creation, the projection of genuine emotions, and the resonance with the reader. Perhaps this is the key.</p> #</span> The "value" of AI </span></span>def</span></span> ai_value</span></span></span>(</span></span>input</span>)</span></span>:</span></span> </span> return</span> optimize</span></span></span></span>(</span>objective_function</span></span></span></span>(</span>input</span></span>)</span></span>)</span></span> </span> </span>#</span> The "value" of humans </span></span>def</span></span> human_value</span></span></span>(</span></span>experience</span>)</span></span>:</span></span> </span> return</span> meaning</span></span></span></span>(</span> </span></span> context</span>=</span>life_history</span></span>,</span> </span></span> emotion</span>=</span>feeling</span></span>,</span> </span></span> relation</span>=</span>others</span></span>,</span> </span></span> time</span>=</span>mortality</span></span> </span></span> )</span></span> </span></code></pre> </a> The Humanistic Return of Technology</h3> Therefore, creators using AI tools bear a new ethical responsibility. Regardless of the tool used, their workflow must include: asking profound questions (Idea & Prompting), generating initial material (Generation), filtering and verifying (Filtering & Verification), integrating and refining (Integration & Refinement), and injecting personal insight (Injecting Insight).</p> Traditional Creation: Thought → Creation → Publication </span>AI-Assisted Creation: Thought → Generation → Filtering → Verification → Optimization → Publication </span></code></pre> The key lies in the three intermediate steps—filtering, verification, and optimization. These steps cannot be omitted; they are a fundamental respect for the reader.</p> Just as your reading at this moment—its value lies not in obtaining a standard answer, but in the thinking it stimulates, the awareness this thinking brings, and the change this awareness facilitates.</p> Value is the connection created between you and me, right here, right now, because of this question.</strong></p> </a> What is the Ultimate Order</h3> In our current stage, humans control AI generation. We face not only technical problems but also value choices. Every time we click the "generate" button, we need to ask ourselves: are we creating value or manufacturing noise? Has it been vetted by human wisdom, does it respect the reader's time, does it serve a real need, and will it promote human progress?</p> Yes, will it promote human progress? This is an inviolable biological choice for a collective species, whether in a micro or macro sense. It doesn't matter if it comes from carbon-based life or silicon-based intelligence.</p> Unless, this order is to be determined by non-humans.</p> [1] https://distantprovince.by/posts/its-rude-to-show-ai-output-to-people/</a></p> [2] https://www.cac.gov.cn/2025-03/14/c_1743654684782215.htm/</a></p> [3] https://www.youtube.com/watch?v=dNjClDI6zT4</a></p> [4] "Intuition" borrows Naval Ravikant's interpretation: Intuition is not metaphysics, but the "Taste" that settles in one's mind from experience, thought, and accumulation.</p>

AI时代的思维框架

2025-12-31T00:00:00+00:00

最近做 GUI Agent 相关研究时，忽然发现了这个现阶段能自洽的框架。

整个过去的2025年，无论是自己的学习实践还是行业的发展，所有线索都指向同一个终极问题：

"未来的用户交互形态会是什么？"

我在草稿纸上拆解了这个问题，以便让未来很长一段时间的学习、工作与思考，都能在这个体系里迭代。这个框架很简单：

社会形态 + 技术边界 → 商业模式

工程边界：借用Karpathy的推文</a>：包括但不限于agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations。</li> </ul>
现阶段的 Agent 设计更多是面向现有应用生态，是“替你操作”的执行者（视觉/自动化/设备驱动），它解决的是“不会用/懒得用/流程太长”等问题，这些都算是存量视角。
而我们个人在未来所谓的 AI Native 生态，以及在过渡阶段的共存生态中的存在声量份额，本质上就看你有多少增量视角了。

声量份额：借用GEO的关键指标 SoV(Share of Voice) </blockquote>

本项目受 MapScroll</a> 启发。 </blockquote>
地图是数字化时代重要的基础设施。Agent时代，无论作为Tools还是通过MCP调用，在各类智能场景下的地图数据与使用交互，成为了产品设计新的思考命题。

BuilderStream 以及记忆管理，以模仿访谈的形式生成后修改。 </blockquote> 关于 BuilderStream 的一些心路历程，并持续进行更新。 Q1：我们聊点开始之前的事吧。开发 BuilderStream，肯定不只是因为看到了一个市场机会。我很好奇，是什么个人经历或者说哪个瞬间，让你觉得“我必须要做这么个东西”？ 当然。本身这件事有一个背景，就是我一直以来都在日常和实践中思考：我们应该如何进入超级智能（SuperIntelligence）时代？ 有一天我看到一个帖子：“如果你生活在1915年，你会意识到自己正处于新文化运动之中吗？”它引向了一个现实的问题，你是新时代的生产者，还是消费者？生产者（我称之为 Builders）创造新时代，即使只创造了万里长城的一块砖。消费者的特征是接收和享受成果，并且是滞后于生产过程的。 BuilderStream 的产品初衷，源于一种普遍而深刻的焦虑感，而自然生成的一种对当前信息环境的“反叛”。短视频时代的解构和娱乐、AI带来的信息生产力变革，我们正在经历信息的严重“通货膨胀”和“劣质化”。我发现自己每天花大量时间刷各种 AI 新闻、科技 KOL 解读，但是体验很差。“二手转述者”的信息在传递过程中必然会失真、降噪、甚至被扭曲。虽然它的角色本质上也是一个信息的搬运工，但是它有一个很简单但很重要的原则：100%尊重原始信息，不解构、不曲解、不加工。 Q2：明白。的确从 GPT3.5 发布以来，大模型技术的发展是名副其实的“日新月异”，你也提到了现在的普遍的 FOMO 的心态。在你看来，这种焦虑的根源是什么？ 我觉得可能从三方面解释。 首先是信息爆炸。一百年前，我们的认知障碍是信息的稀缺和封闭；而在今天，信息的过载才是。在没有成熟的认知和知识体系架构下，人往往会迷失，尤其是那些好学的人。 第二个是信息茧房。现在我们都知道的“推荐算法”，只投喂给我们自己的回声，这就形成了一种更隐蔽的信息隔绝，相信用户在刷各种媒体平台的时候已经深有感触。 第三个是我们前面提到的信息解构。一个是那些因为特定目的（比如流量）而碎片化、夸张化甚至曲解的信息，使得独立思考变得异常艰难，因为你的思考“原材料”本身，可能就是被精心筛选过的。另一个是话语体系和认知的差异，就是哪怕你面对面和Builders聊，你们交互的信息也不一定就是一致的。 Q3：所以，面对这种混乱，你的解法似乎很简单直接：回到源头。为什么“Builders”（构建者）——而不是媒体或专家——是你眼中的那个“源头”？ 因为我坚信信息获取的“第一性原理”：一个想法最纯粹、最准确的表达，永远来自于想法的提出者本人。媒体和专家是“二手转述者”，信息每经过一手，就多一层噪音和偏见。 当然，在技术普惠和启蒙上，那些高质量的转述者也是功能无量。 而就对我个人而言， Builders ——那些正在用代码、产品和思想塑造未来的 CEO、CTO 和科学家们——他们是这个时代的“信号源”。那些有着深刻思考并且已经拿过结果的Builder，是AI时代的新的学习教材。所以，BuilderStream 的 Slogan 就是我们的行动指南：Think with Builders，and to be a Builder。我希望直接与构建者同行，以他们的思考重塑自己的认知边界。 Q4：聊聊 BuilderStream 本身吧。它到底是怎么把“回到源头”这个想法，变成一个实实在在的产品的？如果用几句话向一个新用户介绍，它是什么？ 很简单。BuilderStream 本质上是一个基于“构建者”维度组织起来的私有化数据库（markdown 格式），你可以在自己的笔记工具中（如 Obsidian、Notion）借助AI来一起学习。 它包括两个部分（具体参见BuilderStream产品页</a>）。一个是知识数据库本身。通过转译以及不改变原文的处理，收录全球顶尖 AI 构建者的第一手内容——博客、访谈、播客、演讲等等。一个是每日AI热点资讯。来自目前AI最热门的 X(Twitter)、Reddit、Discord、Product Hunt、微信公众号等社区/平台的AI资讯。所有内容都清晰标注来源，并提供原文链接，这是尊重原创，也是鼓励读者去探索原始完整的思想。 Q5：我发现 BuilderStream 一个很有意思的设计，是所有信息都围绕“人”来组织，而不是按时间线或者热点事件。这么设计有什么特别的讲究吗？ 这是 BuilderStream 最核心的设计哲学，同样也是另一个我认为的第一性原理：信息是人的思想的外化。 传统信息流以“热点”为轴，是发散和被动的，你永远在追逐下一个热点，无法形成体系。我以“人”为核心，是纵向聚合和主动的。这意味着你可以清晰地看到 Sam Altman 或 Andrej Karpathy 关于某个主题（比如 AGI 安全）的思想演进脉络。这让你从一个“新闻消费者”，转变为一个“思想的研究者”。你在构建的，是自己的认知框架，而不是被动接收一堆信息碎片。 另一方面，其实就涉及到我为 BuilderStream 设计的一套完整的可生长的「Taxonomy」 ，包括 Tags 和 Properties 两个体系来管理这个越来越大的知识数据库，Builders 只是其中最核心的一个 Tag 和 Property。 我还是更愿意承认我也只是一个搬运工，做了一些爬取清洗的工作。但是我认为我自身的最大优势之一，并且能为这个产品带来的，是我对复杂知识的体系架构设计和管理，也就是这套 taxonomy。 Q6：你为什么会选择用 Markdown 的数据格式作为产品形态，而且首选的是 Obsidian 适配？ 好的，这是两个问题。 关于为什么选择 Markdown，而不是开发一个 BuilderStream App，或者 LLM 更爱的 .json 格式等，这是定位问题。一个是我认可 Andrej Karpathy 提出的"The hottest new programming language is English" 的观点（虽然他这句话的背景是 Vibe Coding），换而言之，markdown 是新的编程语言，它和 .json 在大模型可读性上没有太大的差距，而且他更加读者友好。另一个是 Markdown 格式被绝大多数笔记软件兼容（可能有微小的的差别），能充分与用户原有的知识管理体系融合。 首选 Obsidian，除了个人喜爱因素，也是是看中其本地化特性和开源社区插件生态，尤其是AI Copilot类和Database类插件，极大地增强了 BuilderStream 的应用便利度。 Q7：最后一个问题。当一个用户深度使用 BuilderStream 后，你希望他身上发生什么样的变化？这个产品最终想带给用户的是什么？ 所谓授人以鱼不如授人以渔，我希望用户能建立一种“独立的认知自信”。 一是“Think with Builders”的学习习惯，当面对一个行业热点时，他的第一反应不再是去看媒体怎么说，KOL 怎么解读，而是“等等，让我先看看产品技术团队自己是怎么说的。”他将拥有自己的判断坐标，能主动地去寻找和验证信息，构建自己的观点。 二是“to be a Builder”，BuilderStream 的最终目标，是赋能和激励每一个用户成为 Builder。因为当你开始像 Builder 一样思考时，你离成为一个 Builder 也就不远了。我希望他回顾这个时代时，自己不仅仅是一个「消费者」。 相关链接： [1] https://builderstream.info/</a> [2] https://obsidian.md/</a> Talk to AI｜Manus拆解 2025-07-13T00:00:00+00:00 </a> Manus工作逻辑</h1> [!question] 我们来探讨一下Manus这个产品。他所谓的Agent的工作逻辑是怎么实现的，比如我给他一个任务，他能自动拆解并执行，这个过程的技术原理是什么，具体的技术方案可能是什么？ </blockquote> </a> 核心工作逻辑</h2> Manus 这类 AI Agent 的任务自动拆解和执行，主要基于以下技术架构： </a> 1. 任务理解与规划层</h3> LLM 作为推理引擎：使用大语言模型（如 GPT-4、Claude 等）理解用户意图</li> Chain-of-Thought (CoT) 推理：让模型逐步思考如何将复杂任务分解为子任务</li> ReAct 框架：Reasoning（推理）+ Acting（行动）循环模式</li> </ul> 具体流程： 用户输入 → LLM 分析意图 → 生成执行计划 → 拆解为子任务序列 </code></pre> </a> 2. 任务拆解的技术方案</h3> 方案 A：Prompt Engineering + 结构化输出 # 伪代码示例 prompt = f""" 任务：{user_task} 请将此任务拆解为可执行的步骤，输出 JSON 格式： {{ "steps": [ {{"action": "操作类型", "params": {{}}, "description": "说明"}}, ... ] }} """ plan = llm.generate(prompt) </code></pre> 方案 B：Planning Agent + Tool Library 维护一个工具库（API、浏览器操作、文件操作等）</li> LLM 根据可用工具规划执行路径</li> 类似 LangChain 的 Agent + Tools 模式</li> </ul> </a> 3. 执行层技术栈</h3> 浏览器自动化： Playwright/Puppeteer：控制浏览器行为</li> 视觉定位：使用 GPT-4V 或 Claude 的视觉能力识别页面元素</li> DOM 解析：提取页面结构，定位可交互元素</li> </ul> 动作执行： # 示例：基于视觉的点击操作 screenshot = browser.screenshot() prompt = f"在这个截图中，'登录'按钮的坐标是？" coordinates = vision_llm.analyze(screenshot, prompt) browser.click(coordinates) </code></pre> </a> 4. 反馈与自我修正机制</h3> 执行动作 → 观察结果 → 判断是否成功 ↓ 失败 重新规划 → 调整策略 → 再次执行 </code></pre> 关键技术： 状态检测：通过截图、DOM 变化判断执行结果</li> 错误恢复：LLM 分析失败原因，生成新计划</li> 记忆系统：向量数据库存储历史执行经验</li> </ul> </a> 可能的完整技术架构</h2> ┌─────────────────────────────────────┐ │ 用户输入层 (自然语言任务) │ └──────────────┬──────────────────────┘ ↓ ┌──────────────────────────────────────┐ │ 规划层 (Planning Agent) │ │ -

// 结果：LLM 可能回复自然语言，难以解析 // ✅ 好的做法：严格的结构化 Prompt const goodPrompt = ` 你是一个任务规划专家。用户请求如下： "${userInput}" 【当前上下文】 - 用户位置：${userLocation} - 当前时间：${currentTime} - 用户偏好：${userPreferences} 【可用工具列表】 ${availableTools.map(tool => ` - ${tool.name}: ${tool.description} 参数: ${JSON.stringify(tool.parameters)} 示例: ${tool.example} `).join('\n')} 【输出要求】 必须返回有效的 JSON，格式如下： { "reasoning": "你的推理过程（200字内）", "tasks": [ { "id": "task_1", "tool": "工具名称（必须从上面列表选择）", "params": {具体参数}, "dependencies": ["task_0"], // 依赖的任务 ID "description": "这步做什么" } ], "expected_outcome": "预期结果描述" } 【关键规则】 1. 任务 ID 必须唯一，格式为 task_N 2. dependencies 必须引用已存在的任务 ID 3. 第一个任务的 dependencies 必须为空数组 4. 工具名称必须完全匹配列表中的名称 5. 不要编造工具或参数 现在开始规划： `;

Prompt 版本控制和 A/B 测试</h3> // 实际生产中的 Prompt 管理 class PromptVersionControl { // 存储在数据库，支持热更新 async getActivePrompt(name: string): Promise<string> { const version = await this.db.query(` SELECT content, metadata FROM prompts WHERE name = $1 AND active = true ORDER BY version DESC LIMIT 1 `, [name]); return version.content; } // A/B 测试：随机选择不同版本的 Prompt async getPromptWithABTest(name: string, userId: string): Promise<string> { const variants = await this.db.query(` SELECT content, variant_id FROM prompt_variants WHERE name = $1 AND active = true `, [name]); // 根据用户 ID 一致性哈希分配变体 const variantIndex = this.consistentHash(userId, variants.length); const selected = variants[variantIndex]; // 记录使用的变体（用于后续分析） await this.logVariantUsage(userId, selected.variant_id); return selected.content; } // 分析不同 Prompt 变体的效果 async analyzeVariants(name: string): Promise<VariantAnalysis[]> { const stats = await this.db.query(` SELECT v.variant_id, COUNT(*) as usage_count, AVG(f.rating) as avg_rating, AVG(e.duration_ms) as avg_duration, SUM(e.tokens_used) as total_tokens FROM prompt_variants v JOIN executions e ON e.prompt_variant_id = v.variant_id LEFT JOIN feedback f ON f.execution_id = e.id WHERE v.name = $1 GROUP BY v.variant_id `, [name]); return stats.map(s => ({ variant_id: s.variant_id, metrics: { usage: s.usage_count, satisfaction: s.avg_rating, performance: s.avg_duration, cost: s.total_tokens * 0.000015 // Claude token 价格 }, confidence_interval: this.calculateCI(s) })); } } </code></pre> </a> 2. 成本控制和监控</h3> class CostMonitor { // 实时跟踪成本 async trackCost(sessionId: string, event: CostEvent) { const cost = this.calculateCost(event); await this.db.insert('cost_tracking', { session_id: sessionId, event_type: event.type, // 'llm_call', 'tool_execution' provider: event.provider, // 'anthropic', 'openai' tokens_used: event.tokens, cost_usd: cost, timestamp: Date.now() }); // 检查是否超过预算 const sessionTotal = await this.getSessionCost(sessionId); if (sessionTotal > this.budgetLimit) { throw new BudgetExceededError(`会话成本超过限制: $${sessionTotal}`); } } private calculateCost(event: CostEvent): number { const pricing = { 'claude-sonnet-4-5': { input: 0.000003, // $3 per MTok output: 0.000015 // $15 per MTok }, 'claude-haiku-3': { input: 0.00000025, output: 0.00000125 } }; const rate = pricing[event.model]; return (event.input_tokens * rate.input) + (event.output_tokens * rate.output); } // 成本优化建议 async suggestOptimizations(sessionId: string): Promise<Optimization[]> { const analysis = await this.analyzeCostBreakdown(sessionId); const suggestions: Optimization[] = []; // 如果 LLM 调用次数过多 if (analysis.llm_calls > 10) { suggestions.push({ type: 'reduce_llm_calls', impact: 'high', suggestion: '考虑缓存常见查询或批量处理任务', potential_saving: analysis.llm_cost * 0.4 }); } // 如果使用了大模型处理简单任务 if (analysis.simple_tasks_with_large_model > 5) { suggestions.push({ type: 'use_smaller_model', impact: 'medium', suggestion: '简单任务使用 Claude Haiku 而非 Sonnet', potential_saving: analysis.simple_task_cost * 0.8 }); } return suggestions; } } </code></pre> </a> 3. 错误恢复和降级策略</h3> class GracefulDegradation { // 定义服务降级级别 private degradationLevels = { FULL_SERVICE: 0, // 所有功能正常 REDUCE_QUALITY: 1, // 减少质量但保持功能 ESSENTIAL_ONLY: 2, // 只保留核心功能 FALLBACK_MODE: 3 // 使用备用方案 }; private currentLevel = this.degradationLevels.FULL_SERVICE; // 根据系统状态自动降级 async handleSystemStress(metrics: SystemMetrics) { if (metrics.error_rate > 0.3) { await this.degradeTo(this.degradationLevels.FALLBACK_MODE); } else if (metrics.response_time > 10000) { await this.degradeTo(this.degradationLevels.REDUCE_QUALITY); } else if (metrics.cost_rate > this.costThreshold) { await this.degradeTo(this.degradationLevels.ESSENTIAL_ONLY); } } private async degradeTo(level: number) { this.currentLevel = level; switch (level) { case this.degradationLevels.REDUCE_QUALITY: // 使用更便宜的模型 this.llmConfig.model = 'claude-haiku-3'; // 减少工具数量 this.toolRegistry.disableNonEssential(); break; case this.degradationLevels.ESSENTIAL_ONLY: // 只保留核心功能 this.disableFeatures(['advanced_search', 'personalization']); // 增加缓存使用 this.cacheConfig.ttl = 3600; // 1小时 break; case this.degradationLevels.FALLBACK_MODE: // 使用预定义的规则替代 LLM this.useRuleBasedFallback = true; // 返回模板化回复 this.useTemplateResponses = true; break; } logger.warn(`System degraded to level ${level}`); } // 规则引擎降级（不使用 LLM） private async ruleBasedPlanning(userQuery: string): Promise<TaskPlan> { // 使用简单的关键词匹配 if (userQuery.includes('餐厅') || userQuery.includes('预订')) { return { tasks: [ { id: 'task_1', tool: 'search_restaurants', params: {} }, { id: 'task_2', tool: 'make_reservation', params: {}, dependencies: ['task_1'] } ] }; } if (userQuery.includes('天气')) { return { tasks: [{ id: 'task_1', tool: 'get_weather', params: {} }] }; } // 默认返回通用回复 return { tasks: [{ id: 'task_1', tool: 'general_search', params: { query: userQuery } }] }; } } </code></pre> </a> 四、总结：Manus 开发者的核心能力</h2> </a> 必备技能清单</h2> </a> 1. Prompt Engineering（最重要）</h3> 结构化 Prompt 设计：用严格的格式、明确的输出要求和 JSON Schema 约束 LLM 的回复，避免随机性</li> Few-Shot Learning：在 Prompt 中给 LLM 展示 2-3 个优秀示例，让它模仿正确的输出格式和推理方式</li> Chain-of-Thought 引导：要求 LLM 在 JSON 中包含 reasoning</code> 字段，把思考过程写出来再给答案，提升准确性</li> JSON Schema 约束：用代码验证 LLM 输出的 JSON 结构是否符合预期，不符合就重试或报错</li> </ul> </a> 2. 系统设计</h3> 任务依赖图解析：用拓扑排序算法理清任务的先后顺序，确保 task_2 依赖的 task_1 结果已经拿到</li> 并发执行优化：识别哪些任务互不依赖可以同时跑，用 Promise.all</code> 并行执行节省时间</li> 错误恢复机制：任务失败时自动重试 3 次，还不行就换备用工具或让 LLM 重新规划</li> 降级策略：系统压力大时自动切换到更便宜的模型、减少功能或用规则引擎替代 LLM</li> </ul> </a> 3. LLM 工程</h3> Token 优化：只传必要信息给 LLM，用摘要代替原始数据，用缓存避免重复调用，降低成本</li> 流式输出：边生成边返回（像 ChatGPT 打字效果），用户体验更好且不用等所有内容生成完</li> 上下文窗口管理：用向量搜索只保留与当前对话最相关的历史记录，避免超出 token 限制</li> 模型选择策略：简单任务用便宜的 Haiku，复杂推理用强大的 Sonnet，根据任务难度动态选模型</li> </ul> </a> 4. 可观测性</h3> 执行轨迹记录：把 LLM 的每个决策、工具调用、结果验证全记录到数据库，方便事后分析为什么出错</li> 异常检测：自动发现异常模式（如同一任务执行 10 次、成本突然暴涨），及时预警</li> A/B 测试：同时测试多个版本的 Prompt，用数据说话选出成功率最高的那个</li> 成本监控：实时统计每个会话花了多少钱，超预算就停止或降级，避免账单爆炸</li> </ul> </a> 关键设计原则</h2> </a> 1. 让 LLM 专注于推理，而非记忆</h3> 用工具提供实时数据：不要让 LLM 回忆"旧金山有哪些餐厅"，而是调用 Yelp API 工具获取最新真实数据</li> 用向量数据库存储知识：把历史对话、用户偏好等信息存到向量库，需要时通过相似度搜索提取，而不是塞进 Prompt</li> 用规则引擎处理确定性逻辑：对于"订单金额大于100就打9折"这种固定规则，直接写代码判断，不需要问 LLM</li> </ul> </a> 2. 永远有 Plan B</h3> 每个工具都有备用方案：主 API（如 Yelp）挂了自动切换到备用 API（如 Google Places），不让用户感知到故障</li> 关键路径有降级策略：LLM 调用失败时，改用更便宜的模型或预设的规则引擎继续完成任务</li> LLM 失败时用规则引擎：如果 LLM 连续 3 次都没生成有效计划，就用关键词匹配等简单规则给出基础回复</li> </ul> </a> 3. 透明化而非黑盒</h3> 记录完整的决策过程：把"为什么选这个餐厅""为什么调用这个工具"等推理过程存到数据库，方便事后审查</li> 可视化执行轨迹：用时间线图表展示 Agent 执行的每个步骤、耗时、成功/失败状态，让开发者一眼看懂流程</li> 支持人工干预：在关键节点（如最终预订前）暂停让用户确认，或允许开发者手动修正 Agent 的决策</li> </ul> </a> 4. 持续优化</h3> A/B 测试 Prompt：同时跑两个版本的 Prompt（如"请详细推理" vs "请简洁回答"），统计哪个成功率更高</li> 监控成本和性能：追踪每个功能的 token 消耗、响应时间、成功率，发现瓶颈后针对性优化</li> 从失败案例学习：分析失败的会话记录，提取共性问题（如"搜索结果为空时经常卡住"），改进 Prompt 或工具逻辑</li> </ul> 这些原则的核心思想就是：把 LLM 当作不稳定但强大的推理引擎，用工程手段保证系统整体的稳定性和可控性。 这就是 Manus 背后完整的开发侧实现！核心就是把 LLM 当作"大脑"，通过精心设计的 Prompt 和工具系统，让它能够可靠地规划和执行复杂任务。 The Dignity of Information 2025-06-20T00:00:00+00:00 There has always been a voice of rejection against AI-generated content within tech communities. "The text used to have an innate proof-of-thought, a basic token of humanity." In his blog post^{[1], Alex points out that it is impolite to present AI-generated content to others without personal filtering and reflection. AI content forwarded without thought is like a "virus" or "slop", which he believes wastes the recipient's time and energy. Therefore, he advocates for a new "AI etiquette": AI-generated content should only be shared if the sharer has adopted it, is willing to take responsibility for its output, or if the recipient has explicitly consented.} The "Measures for the Management of Generative Artificial Intelligence Services", effective September 1, 2025, issued by the Cyberspace Administration of China^{[2], is, in a sense, at the center of this topic's vortex.} A century ago, the scarcity and closure of information were the primary obstacles to cognition. But today, it is information overload. I do not intend to deliberately deepen this issue, but it is indeed a philosophical speculation on the nature of information, creative ethics, and human dignity. </a> There is Nothing in the Human Mind That AI Cannot Replicate</h2> "There is nothing in the human mind that AI cannot replicate, and AI already possesses subjective experience." — 2024 AI for Good, Geoffrey Hinton^{[3] </blockquote>}I agree with this viewpoint. (See When Boundaries Disappear</a>) Of course, this is not a view one needs to take a side on right now, much like believing in aliens, it is purely based on personal intuition^{[4]. This serves as the backdrop for discussing AI Generated vs. Human Made, shifting our focus and discussion to "What kind of information is valuable?" rather than whether it's generated by AI or made by humans, regardless of the level of AI that generated it. In this sense, there is no difference between content generated by AI and by another person.} Let's first talk about "value", which you can also roughly understand as "meaning." </a> What is So-Called "Value"</h2> </a> Three Perspectives on Value</h3> Objectivist Perspective: Value as a Property Plato believed in the "Good" existing in the world of Forms; value is an inherent property of things. The beauty of a flower, the justice of an act, the truth of an argument—their value exists independently of the observer. So, if an unread article still has value, where does its value reside? </li> Subjectivist Perspective: Value as a Projection Nietzsche declared, "There are no facts, only interpretations." Value is not discovered but created. It is humans who project meaning onto an originally neutral world. If value is purely subjective, does "universal value" still have meaning? </li> Relational Perspective: Value as an Emergence I believe more people, like myself, tend to think that value is neither entirely objective nor purely subjective, but emerges in relationships. It exists in the encounter between a subject and an object; the value of my article is realized the moment a reader reads it. It exists in the relationship between demand and supply; my article is more valuable to an AI practitioner than to someone uninterested in the topic. It also exists in the intersection of time and space; this same article has different values at different moments. </li> </ul> I wonder if you've sensed that, regardless of the perspective, "purpose" looms as a standard for judging value, be it a subjective personal need or an objective destination for humanity. </a> The Nihilistic Trap of Value</h3> Kant argued that only "persons" have intrinsic value (dignity), while everything else merely has a price. Buddhism, on the other hand, posits that even the "self" is an illusion, so how can we speak of intrinsic value? This is the definitional nihilism of value. If we continue to ask: where does the value of the standard for judging value itself come from? This infinite recursion is the boundary nihilism of value (it may well be the boundary of human reason). I don't want to fall into this deconstructionist trap of "why of why of why..." but rather to stop at a certain "why." This is part of what I mean by the "experiencer." Wittgenstein said, "My propositions serve as elucidations in the following way: anyone who understands me eventually recognizes them as nonsensical, when he has used them—as steps—to climb up beyond them. He must, so to speak, throw away the ladder after he has climbed up it." The recursive nature of value is like this ladder—its meaning lies not in endlessly questioning, but in making us realize that: At some point, we must stop asking "why" and start acknowledging "it just is." </blockquote> To start acknowledging "it just is" is the formation of the "self". Like axioms in mathematics that require no further proof, it means your value system has foundational beliefs—biological, social, individual, and even transcendent. </a> The Three Elements of Value</h3> Returning to the question, "What kind of information is valuable?" I believe that information worth our reading should possess at least one or more of the following characteristics: Intellectual Increment: Does it offer a unique perspective, profound insight, or high-quality integration? The value of information lies in reducing uncertainty. If AI-generated content is merely a repetition, patchwork, and paraphrase of existing knowledge, it is "information entropy" garbage. Truly valuable content is when humans use AI as a lever for their thinking to pry open new frontiers of knowledge. The core of this lies in the intellectual height of the questioner, not the generative capability of the AI. </li> Utility Condensation: Does it save me a significant amount of time and energy? For example, a high-quality research report assisted by AI, which distills hundreds of financial reports and news articles into a few pages of conclusions and charts. Here, the AI is not the original creator of the content but an extension of the human expert's will, a powerful "information compressor." What we consume is not the AI's words, but the time, experience, and judgment of the expert behind them. </li> Contract of Accountability: Is the publisher of the content willing to back it with their own reputation? Regardless of how the content is generated, once published, the publisher establishes an implicit contract with the consumer. The publisher promises that they have completed the work of filtering, verifying, and refining for us, and that this content is worth our time. This act of collateralizing personal or institutional credibility is key to distinguishing a "creator" from a "slacker." </li> </ul> </a> Value Reconstruction in the AI Era</h2> </a> The Imbalance of Labor and Value</h3> Traditional creation follows an implicit social contract: the creator invests time and effort (referring only to thoughtful investment), and the reader repays with attention and recognition. This equivalence of time constitutes the basic dignity of information exchange. A meticulously written novel, a well-thought-out code pull request, a rigorous academic paper—their value is partly derived from the "time cost" invested by the creator. AI shatters this balance. When the cost of labor approaches zero, we naturally feel the sense of rejection mentioned at the beginning, while subjectively ignoring whether it has value. When AI can generate content infinitely, it is in effect making finite human attention consume infinite machine output. This leads to efficiency and ethical questions: Do we have the right to use low-cost generation to consume the high-cost lives of others? This may eventually evolve into a debate on how silicon-based and carbon-based life can coexist. Furthermore, besides the result, human creation has another crucial dimension—the meaning of the process itself. The evolution of thought during creation, the projection of genuine emotions, and the resonance with the reader. Perhaps this is the key. # The "value" of AI def ai_value(input): return optimize(objective_function(input)) # The "value" of humans def human_value(experience): return meaning( context=life_history, emotion=feeling, relation=others, time=mortality ) </code></pre> </a> The Humanistic Return of Technology</h3> Therefore, creators using AI tools bear a new ethical responsibility. Regardless of the tool used, their workflow must include: asking profound questions (Idea & Prompting), generating initial material (Generation), filtering and verifying (Filtering & Verification), integrating and refining (Integration & Refinement), and injecting personal insight (Injecting Insight). Traditional Creation: Thought → Creation → Publication AI-Assisted Creation: Thought → Generation → Filtering → Verification → Optimization → Publication </code></pre> The key lies in the three intermediate steps—filtering, verification, and optimization. These steps cannot be omitted; they are a fundamental respect for the reader. Just as your reading at this moment—its value lies not in obtaining a standard answer, but in the thinking it stimulates, the awareness this thinking brings, and the change this awareness facilitates. Value is the connection created between you and me, right here, right now, because of this question. </a> What is the Ultimate Order</h3> In our current stage, humans control AI generation. We face not only technical problems but also value choices. Every time we click the "generate" button, we need to ask ourselves: are we creating value or manufacturing noise? Has it been vetted by human wisdom, does it respect the reader's time, does it serve a real need, and will it promote human progress? Yes, will it promote human progress? This is an inviolable biological choice for a collective species, whether in a micro or macro sense. It doesn't matter if it comes from carbon-based life or silicon-based intelligence. Unless, this order is to be determined by non-humans.
