Anthropic 公開承諾 Claude 不放廣告。原因不是商業考量，而是價值觀：廣告誘因結構會與「誠實為使用者服務」的核心原則相衝突——即使是表面分開的廣告，也會推動產品優化「停留時間」而非「真正幫助」。Anthropic 的商業模式靠企業合約與訂閱，未來會支援 agentic commerce（AI 代使用者購物），但所有商務互動都必須由使用者發起、而非廣告商驅動。

There are many good places for advertising. A conversation with Claude is not one of them.
許多地方都適合放廣告。和 Claude 的對話不是其中之一。
新字：advertising
句型解析
兩句形成強烈對比。第一句先肯定廣告的普遍價值（many good places），第二句用 not one of them（不是其中之一）收尾，典型的「先肯定再轉折」修辭。這種開場在商業倫理文章中極常見，既不顯得對廣告本身有敵意，又明確劃清界線。
Advertising drives competition, helps people discover new products, and allows services like email and social media to be offered for free. We've run our own ad campaigns, and our AI models have, in turn, helped many of our customers in the advertising industry.
廣告帶動競爭、幫助人們發現新產品，也讓 email、社群媒體這類服務能夠免費提供。我們自己也跑過廣告活動，我們的 AI 模型也反過來協助了許多廣告業的客戶。
新字：ad campaign, in turn
句型解析
allows services like email and social media to be offered for free：這裡用「allow X to be + 過去分詞」的不定詞被動式。完整邏輯是「廣告讓（某些）服務得以被免費提供」。A1 讀者容易卡在 to be offered——它不是過去式，而是「被提供」的被動不定詞。
But including ads in conversations with Claude would be incompatible with what we want Claude to be: a genuinely helpful assistant for work and for deep thinking.
但把廣告放進與 Claude 的對話之中，會與我們想讓 Claude 成為的角色不相容：一位真正能幫助工作與深度思考的助手。
新字：incompatible, genuinely, helpful assistant
We want Claude to act unambiguously in our users' interests. So we've made a choice: Claude will remain ad-free. Our users won't see "sponsored" links adjacent to their conversations with Claude; nor will Claude's responses be influenced by advertisers or include third-party product placements our users did not ask for.
我們希望 Claude 毫無模糊地站在使用者的利益這一邊。所以我們做了一個選擇：Claude 會維持無廣告。使用者不會在 Claude 對話旁看到「贊助」連結；Claude 的回應也不會受廣告商影響，也不會包含使用者沒主動要求的第三方產品置入。
新字：unambiguously, in one's interests, ad-free, sponsored, adjacent, third-party, product placement
句型解析
nor will Claude's responses be influenced...：nor 開頭的倒裝句。當前一句是否定（won't see...），接下來用 nor 延續另一個否定時，會倒裝為「nor + 助動詞 + 主詞」。正常語序是 Claude's responses will not be influenced...，加了 nor 後變成 nor will Claude's responses be influenced...。商業英文與法律英文常用此結構。
When people use search engines or social media, they've come to expect a mixture of organic and sponsored content. Filtering signal from noise is part of the interaction.
signal from noise（訊號與雜訊）源自通訊工程／資訊理論，指「有用資訊」與「無用干擾」的分離。科技圈、資料科學圈借用為慣用比喻——任何要從大量雜訊中找出真正重要資訊的情境。Nate Silver 的暢銷書名就叫 The Signal and the Noise。
Conversations with AI assistants are meaningfully different. The format is open-ended; users often share context and reveal more than they would in a search query. This openness is part of what makes conversations with AI valuable, but it's also what makes them susceptible to influence in ways that other digital products are not.
與 AI 助手的對話在本質上不一樣。形式是開放式的；使用者經常分享脈絡、透露比在搜尋關鍵字時更多的資訊。這份開放性既是 AI 對話的價值所在，但也是它之所以比其他數位產品更容易被影響的原因。
Our analysis of conversations with Claude (conducted in a way that keeps all data private and anonymous) shows that an appreciable portion involve topics that are sensitive or deeply personal—the kinds of conversations you might have with a trusted advisor. Many other uses involve complex software engineering tasks, deep work, or thinking through difficult problems. The appearance of ads in these contexts would feel incongruous—and, in many cases, inappropriate.
我們對 Claude 對話的分析（以保有資料隱私與匿名的方式進行）顯示，相當一部分涉及敏感或非常個人的話題——那種你會與信任的顧問才會聊的內容。其他許多用途則牽涉複雜的軟體工程任務、深度工作、或反覆思考難題。廣告出現在這些情境中會顯得格格不入——在許多情況下甚至是不得體的。
新字：conduct, anonymous, appreciable, sensitive, advisor, deep work, incongruous, inappropriate
We still have much to learn about the impact of AI models on the people who use them. Early research suggests both benefits—like people finding support they couldn't access elsewhere—and risks, including the potential for models to reinforce harmful beliefs in vulnerable users. Introducing advertising incentives at this stage would add another level of complexity. Our understanding of how models translate the goals we set them into specific behaviors is still developing; an ad-based system could therefore have unpredictable results.
關於 AI 模型對使用者的影響，我們還有很多要學習的。早期研究顯示出好處——例如人們得到在別處無法取得的支援——也顯示出風險，包括模型可能強化脆弱使用者的有害信念。在現階段引入廣告誘因，會再多加一層複雜性。我們對「模型如何把我們設定的目標轉化為具體行為」的理解仍在發展之中；基於廣告的系統因此可能產生難以預料的結果。
Being genuinely helpful is one of the core principles of Claude's Constitution, the document that describes our vision for Claude's character and guides how we train the model. An advertising-based business model would introduce incentives that could work against this principle.
「真正的幫助」是 Claude Constitution（Claude 憲章）的核心原則之一——這份文件描繪我們對 Claude 性格的願景，也指引我們如何訓練模型。以廣告為基礎的商業模式會引入與這個原則相互牴觸的誘因。
新字：core principle, Constitution, vision, character, work against
文化脈絡
Anthropic 把訓練 Claude 的指導文件稱為 Claude's Constitution（Claude 的憲章）。這個命名有特殊意義——不是 "guidelines"（指引）或 "rules"（規則），而是 Constitution（憲法／根本大法），暗示它是 Claude 存在的基礎架構、不可違背的最高原則。Anthropic 的「Constitutional AI」方法論也是學界有名的概念。
Consider a concrete example. A user mentions they're having trouble sleeping. An assistant without advertising incentives would explore the various potential causes—stress, environment, habits, and so on—based on what might be most insightful to the user. An ad-supported assistant has an additional consideration: whether the conversation presents an opportunity to make a transaction. These objectives may often align—but not always. And, unlike a list of search results, ads that influence a model's responses may make it difficult to tell whether a given recommendation comes with a commercial motive or not. Users shouldn't have to second-guess whether an AI is genuinely helping them or subtly steering the conversation towards something monetizable.
second-guess 是常見片語動詞，意思是「事後質疑、馬後砲地懷疑」。字面「第二次猜測」，引申為「對別人的判斷／動機產生懷疑」。"Don't second-guess me"（別質疑我）。這裡說使用者不該需要 second-guess AI 的動機，意思是「不該讓使用者還要懷疑 AI 的真誠度」。
Even ads that don't directly influence an AI model's responses and instead appear separately within the chat window would compromise what we want Claude to be: a clear space to think and work. Such ads would also introduce an incentive to optimize for engagement—for the amount of time people spend using Claude and how often they return. These metrics aren't necessarily aligned with being genuinely helpful. The most useful AI interaction might be a short one, or one that resolves the user's request without prompting further conversation.
即使是那些不直接影響 AI 回應、而是分開顯示在聊天視窗中的廣告，也會破壞我們期望 Claude 成為的樣子：一個清晰的思考與工作空間。這種廣告還會帶來「優化互動時長」的誘因——人們使用 Claude 的時間長度、回訪頻率。這些指標不必然與「真正有幫助」一致。最有用的 AI 互動可能很短，或者是在不引發後續對話的情況下就解決使用者需求的那種。
這段的核心論述是「即使 A（廣告不直接影響回應），B（誘因仍會扭曲）」——典型的 Even X would... 反設條件句。常用於預先反駁對方可能的辯解：「就算你們的廣告方式比較乾淨，還是會有問題」。這是論證邏輯的重要技巧。
We recognize that not all advertising implementations are equivalent. More transparent or opt-in approaches—where users explicitly choose to see sponsored content—might avoid some of the concerns outlined above. But the history of ad-supported products suggests that advertising incentives, once introduced, tend to expand over time as they become integrated into revenue targets and product development, blurring boundaries that were once more clear-cut. We've chosen not to introduce these dynamics into Claude.
blurring boundaries that were once more clear-cut：blurring 是現在分詞作補語，修飾前面的 expand over time——描述擴張過程中發生的副作用。that were once more clear-cut 是關係子句修飾 boundaries，once 在這裡是「曾經」（時間副詞，不是「一旦」）。整句意思：「擴張的過程，讓原本比較清晰的界線變得模糊」。
Our approach
Anthropic 的做法
Anthropic is focused on businesses, developers, and helping our users flourish. Our business model is straightforward: we generate revenue through enterprise contracts and paid subscriptions, and we reinvest that revenue into improving Claude for our users. This is a choice with tradeoffs, and we respect that other AI companies might reasonably reach different conclusions.
Anthropic 聚焦在企業、開發者，以及協助使用者蓬勃發展。我們的商業模式很直接：透過企業合約與付費訂閱產生營收，並把營收再投資回改善 Claude，讓使用者受惠。這是一個有取捨的選擇，我們也尊重其他 AI 公司可能基於合理考量做出不同結論。
we respect that other AI companies might reasonably reach different conclusions 是一句極為委婉的「暗嗆」。表面上說「尊重對方」，實質上在指「我們選擇不做廣告，那些選擇做廣告的 AI 公司（暗指 Google、可能暗示 OpenAI 未來走向）並非不合理，但我們認為有更好的做法」。這種「禮貌性競爭話術」是矽谷公關文字的典型風格。
Expanding access to Claude is central to our public benefit mission, and we want to do it without selling our users' attention or data to advertisers. To that end, we've brought AI tools and training to educators in over 60 countries, begun national AI education pilots with multiple governments, and made Claude available to nonprofits at a significant discount. We continue to invest in our smaller models so that our free offering remains at the frontier of intelligence, and we may consider lower-cost subscription tiers and regional pricing where there is clear demand for it. Should we need to revisit this approach, we'll be transparent about our reasons for doing so.
擴大 Claude 的可用性是我們公益使命的核心，我們希望在不出賣使用者注意力與資料給廣告商的前提下做到。為此，我們已把 AI 工具與訓練帶到超過 60 個國家的教育工作者手中、與多國政府開展國家級 AI 教育試點、並以顯著折扣提供給非營利組織。我們也持續投資較小型模型，讓免費版維持在智慧前沿；在有明確需求的地方，我們可能考慮較低價的訂閱方案與區域訂價。若未來我們需要重新檢視這個方針，我們會透明地說明原因。
Should we need to revisit this approach, we'll be transparent...：倒裝假設句。正常語序是 If we should need to revisit...，正式英文可省略 if 並把助動詞 should 提前，變成 Should we need to...。這是政策與法律文件的典型寫法，語氣比 if 更正式、更審慎。
Supporting commerce
支持商務
AI will increasingly interact with commerce, and we look forward to supporting this in ways that help our users. We're particularly interested in the potential of agentic commerce, where Claude acts on a user's behalf to handle a purchase or booking end to end. And we'll continue to build features that enable our users to find, compare, or buy products, connect with businesses, and more—when they choose to do so.
AI 未來會越來越多地與商務互動，我們期待以幫助使用者的方式來支持這件事。我們特別感興趣的是 agentic commerce（代理式商務）的潛力——Claude 代表使用者處理整個採購或預訂流程，從頭到尾。我們也會持續打造讓使用者能搜尋、比較、購買產品，與商家聯繫的功能——當使用者主動選擇這樣做的時候。
新字：increasingly, commerce, agentic, on one's behalf, purchase, booking, end to end
文化脈絡
agentic commerce 是 AI 產業的新名詞，指「AI 代理人（agent）代替使用者完成交易」——從比價、下單到付款，整個流程由 AI 自主處理。end to end（從頭到尾、端到端）強調全流程覆蓋。這是 2026 年 AI 產品的重要新方向，與傳統「搜尋 + 廣告」的商業模式不同。
We're also exploring more ways to make Claude a focused space to be at your most productive. Users can already connect third-party tools they use for work—like Figma, Asana, and Canva—and interact with them directly within Claude. We expect to introduce many more useful integrations and expand this toolkit over time.
我們也在探索讓 Claude 成為「你最有生產力的聚焦空間」的更多方式。使用者已經可以連接工作中會用到的第三方工具——像 Figma、Asana、Canva——並在 Claude 內直接操作。我們預期會引入更多有用的整合，並逐步擴大這個工具箱。
新字：focused space, at your most productive, integration, toolkit
句型解析
a focused space to be at your most productive：at your most + adj.（在你最...的狀態）是很漂亮的英文結構。例如 at your best（處於最佳狀態）、at your most creative（處於最有創意的狀態）。這裡 at your most productive 意思是「最有生產力的狀態」。
All third-party interactions will be grounded in the same overarching design principle: they should be initiated by the user (where the AI is working for them) rather than an advertiser (where the AI is working, at least in part, for someone else). Today, whether someone asks Claude to research running shoes, compare mortgage rates, or recommend a restaurant for a special occasion, Claude's only incentive is to give a helpful answer. We'd like to preserve that.
所有第三方互動都會以同樣的核心設計原則為基礎：互動必須由使用者發起（AI 為使用者工作），而不是由廣告商發起（AI 至少部分在為其他人工作）。今天，不管使用者是請 Claude 研究跑鞋、比較房貸利率，或是推薦特殊場合的餐廳，Claude 唯一的動機就是給一個有幫助的答案。我們希望保留這一點。
新字：grounded, overarching, initiate, mortgage rate, special occasion, preserve
A trusted tool for thought
值得信賴的思考工具
We want our users to trust Claude to help them keep thinking—about their work, their challenges, and their ideas.
我們希望使用者相信 Claude 能陪伴他們持續思考——關於他們的工作、他們面對的挑戰、他們的點子。
Our experience of using the internet has made it easy to assume that advertising on the products we use is inevitable. But open a notebook, pick up a well-crafted tool, or stand in front of a clean chalkboard, and there are no ads in sight.
新字：assume, inevitable, notebook, well-crafted, chalkboard, in sight
句型解析
open a notebook, pick up a well-crafted tool, or stand in front of a clean chalkboard, and there are no ads in sight.：這是「imperative + and + result」的修辭結構——用祈使句開頭，後面接 and，自然引出結果。效果類似於中文的「你只要（做 X），（就會得到 Y）」。這種句型在演講與政策文章中極有感染力，因為它讓讀者親身「做」那個動作。
We think Claude should work the same way.
我們認為 Claude 應該以同樣的方式運作。

這是一篇典型的「價值觀宣告」（value statement）文章——不是功能發表、不是技術解說，而是公開立下一條原則。這類文章在 AI 產業中越來越常見，因為商業模式的選擇本身就是對使用者的一種承諾。
結尾用 open a notebook, pick up a well-crafted tool, or stand in front of a clean chalkboard 三個具象動作收束，把「乾淨的思考空間」這個抽象概念具象化。這種從抽象到具象的結尾，是英文論述文的高階技巧——讀者不只理解了論點，還產生了畫面感。
文章刻意避免點名競爭對手（Google、OpenAI），但用 we respect that other AI companies might reasonably reach different conclusions 輕描淡寫地劃清界線。這是矽谷公關溝通的經典技巧：批評制度而不批評人。
Claude's Constitution（Claude 的憲章）是 Anthropic 的核心用語——把訓練文件稱為「憲法」而非「規則」或「指引」，暗示它是 Claude 存在的根本法。讀者若要深入理解 Anthropic 的產品哲學，這個詞會反覆出現。
agentic commerce 是 2026 年的新商業模式概念——不靠廣告，靠 AI 代理人完成交易。這可能是 AI 時代取代傳統網路廣告商業模式的關鍵轉型，值得長期追蹤。
