【科技解密】Netflix 正在打造「最懂你的 AI」— 比你更懂你的片單
不想再滑片單?Netflix 升級推薦系統,靈感來自 ChatGPT,打造全新 AI 智慧大腦。它不只記得你看過什麼,更能預測你接下來會愛什麼,連新片都能精準推薦!

你每天打開 Netflix,卻總要滑半天才能選一部片?
Netflix 升級了最新的推薦系統,靈感來自 ChatGPT 的大型語言模型(LLM),打造出一個全新的「AI 智能推薦大腦」,它不只記得你點閱過什麼,更能預測你會愛什麼。
推薦系統升級的 3 大關鍵改變:
- 從「分工模型」變成「統一大腦」
過去推薦系統是多個模型各自作業,現在 Netflix 將它們整合成一個會全面學習你喜好的 AI 模型,像 ChatGPT 一樣全局思考。 - 不只看你點了什麼,而是看「你怎麼看」
AI 會學會你在什麼時間、用什麼裝置、習慣看什麼風格內容,從觀影行為中讀出你的節奏與偏好。 - 新片也能猜中你愛不愛:「冷啟動推薦」技術
即使影片沒人看過,AI 也能根據演員、主題、類型等資訊來預測你會不會喜歡。
系統背後的科技:如何快狠準
- 行為片段切割(Interaction Tokenization):
像 ChatGPT 把句子切成詞,Netflix 把你的觀影行為切成一段段有意義的互動紀錄。 - 稀疏注意力技術(Sparse Attention):
幫助 AI 從你上千次觀看中,找出最重要的學習訊號,大幅提升效率與準確性。 - 混合式嵌入(Hybrid Embedding):
結合影片 ID 與 metadata(如類型、地區、主題等),即便沒人看過,也能「推得像是你選的」。

為什麼這麼重要?
這次的 AI 升級不是單純推薦強化,而是Netflix 正在建立一個理解你文化偏好的智慧系統。
它未來可能不只推薦影集,還會擴展到音樂、遊戲、App、甚至你每天用的所有數位平台。
推薦系統,從此進入 AI 個人化 2.0 時代。
Netflix Is Building an AI That Knows You Better Than You Think
Not just smarter recommendations—Netflix’s AI learns you
Scrolling endlessly on Netflix? This might soon be a thing of the past.
Netflix is building a new kind of AI model inspired by ChatGPT— a foundation model—that doesn’t just react to your clicks, but learns how, when, and why you watch.
What’s New? Here Are the 3 Big Upgrades:
- One Unified AI Brain
Instead of running separate models for “Top Picks” and “Continue Watching,” Netflix is combining everything into one system that learns your taste from every angle. - It Learns How You Watch
Watching comedies on your phone during lunch and thrillers on your TV at night? Netflix’s AI picks up on that. - Cold-Start Ready for New Titles
Even if no one has watched a new release yet, the AI can predict your interest using metadata—like genre, cast, and story type.
The Tech That Makes It Happen
- Interaction Tokenization
Like GPT breaks down text, Netflix turns your watching behavior into structured, learnable events. - Sparse Attention
Helps AI focus on the most meaningful parts of your long viewing history without slowing down. - Hybrid Embeddings
Combines ID-based and metadata-based insights so AI understands what makes two shows “feel” similar—even before you’ve watched them.
Why It’s a Big Deal
Netflix isn’t just making smarter recommendations. It’s building an AI that adapts to you like a digital cultural companion.
It could soon expand beyond shows—recommending music, games, ads, even apps.
This isn’t just personalization. It’s prediction with empathy.
