EU AI Act新規上路：聊天機器人須表明AI身份 | EU AI Act: Chatbots Must Now Disclose They're AI

🇹🇼 EU AI Act新規上路：聊天機器人須表明AI身份
EU AI Act（歐盟人工智慧法案）的透明度規定已於2026年8月2日正式生效，聊天機器人、深偽內容、AI生成文章從現在起都得「表明身份」，違者將由歐盟AI辦公室與各國主管機關開罰。這不只是歐洲的事——只要你的產品有歐盟用戶，這條規定就跟你有關。以下是身為AI工具觀察者，我幫大家整理的重點懶人包。
什麼是EU AI Act透明度規定？
EU AI Act第50條規定，AI系統若會直接與使用者互動、生成或竄改內容，就必須讓使用者知道自己正在跟AI打交道，且標示方式要「一般人不用工具就看得懂」。這是繼2月生效的「禁止類別」（如社會評分系統）之後，第二波正式落地的義務。
聊天機器人現在必須說什麼？
凡是互動式AI系統（客服機器人、AI助理等），除非AI身份已經「顯而易見」，否則必須主動告知使用者對方是AI，不是真人。這代表很多品牌客服頁面上那種偽裝成真人的聊天視窗，現在得加上明顯的AI標示。
深偽內容怎麼標記？
用AI生成或竄改的圖片、影片、音訊（也就是deepfake）必須加上人眼可辨識的標籤，同時要有機器可讀的浮水印，方便平台與監管機關自動偵測。針對公共議題的AI生成文章也要揭露來源，除非有真人編輯把關並負編輯責任。
高風險AI系統為什麼還沒上路？
值得注意的是，EU AI Act真正嚴格的「高風險系統」義務（如醫療、招募用AI）反而被延後——獨立高風險系統延到2027年12月，內嵌在產品裡的則延到2028年8月。目前生效的只是透明度這一塊，代表歐盟選擇先從「使用者知情權」下手，複雜的高風險合規留給企業更多準備時間。
這跟非歐洲的AI團隊有什麼關係？
只要服務對象包含歐盟使用者，不論公司總部在哪，都適用這套透明度規定。對做AI產品或內容的團隊來說，實務上該做的事包括：
- 檢查聊天機器人、客服AI是否有清楚的「這是AI」標示
- AI生成的圖片/影片輸出流程中加入標籤與中繼資料浮水印
- 公開發布的AI生成文章，若無實質人工編審，需加上生成聲明
違規最高罰款可達全球營收一定比例（依情節而定），歐盟AI辦公室已在8月2日同步取得執法權，不是紙老虎。
常見問題 FAQ
Q: 這規定只適用歐盟公司嗎？
A: 不是，只要服務對象涵蓋歐盟使用者，境外公司同樣適用。
Q: 我的AI客服本來就會說「我是AI助理」，還需要做什麼？
A: 只要標示清楚、使用者一望即知，基本上已符合要求，但建議留存標示紀錄以備查核。
Q: 高風險AI系統現在不用管了嗎？
A: 只是期限延後（2027-2028），不是取消，建議提早規劃合規時程。

🇺🇸 EU AI Act: Chatbots Must Now Disclose They're AI
The EU AI Act's transparency obligations officially took effect on August 2, 2026 — meaning chatbots, deepfakes, and AI-generated articles now legally have to identify themselves, with the EU's AI Office and national regulators gaining enforcement power the same day. This isn't just a European problem: if your product serves EU users, this rule applies to you. Here's the practical breakdown.
What Does the EU AI Act Transparency Rule Actually Require?
Under Article 50 of the EU AI Act, any AI system that interacts directly with users or generates/alters content must make its AI nature clear — labeled in a way an ordinary person can understand without needing a detection tool. This is the second wave of obligations to go live, following the "prohibited practices" ban (like social scoring) that started back in February.
What Must Chatbots Disclose Now?
Any interactive AI system — customer service bots, AI assistants — must proactively tell users they're talking to an AI, not a human, unless that's already obvious from context. Plenty of brands' "human-looking" support chat widgets now need a visible AI label.
How Should Deepfakes Be Labeled?
AI-generated or AI-altered images, video, and audio (deepfakes) must carry a human-readable label plus a machine-readable watermark so platforms and regulators can detect them automatically. AI-generated text on matters of public interest also needs a disclosure — unless a human editor has substantively reviewed it and takes editorial responsibility.
Why Haven't High-Risk AI Rules Kicked In Yet?
Interestingly, the EU AI Act's tougher "high-risk system" obligations — covering things like medical or hiring AI — got pushed back instead: standalone high-risk systems now have until December 2027, and those embedded in products until August 2028. What's live today is just the transparency layer, suggesting the EU chose to start with users' "right to know" while giving companies more runway for the harder compliance work.
What Should Non-EU AI Teams Do?
If your service reaches EU users at all, regardless of where your company is based, these transparency rules apply. Practical checklist:
- Audit chatbots and AI support tools for a clear "this is AI" disclosure
- Add visible labels and metadata watermarks to your AI image/video generation pipeline
- Add a generation disclosure to publicly posted AI-written articles that lack substantive human editorial review
Fines scale with global revenue depending on severity, and the AI Office now has real enforcement power as of August 2 — this isn't a paper tiger.
FAQ
Q: Does this only apply to EU-based companies?
A: No — any company serving EU users falls under it, regardless of where it's headquartered.
Q: My AI support bot already says "I'm an AI assistant" — is that enough?
A: If the label is clear and unmistakable to users, you're likely compliant, but keep records of your disclosure for audit purposes.
Q: Can I ignore high-risk AI system rules for now?
A: They're delayed (2027-2028), not cancelled — start planning your compliance timeline early.
