🇹🇼 Discovery Loop全解析：Jeff Dean離開Google創辦AI科研新創
Discovery Loop是Google前首席科學家Jeff Dean在離開待了27年的公司後，於2026年8月創辦的AI新創，目標是用AI自動化整個科學研究流程——從提出實驗假設、動手執行、分析結果到修正方向，全部交給AI代理人以人類無法企及的速度大量平行運作。這起事件不只是一次跳槽，而是Google AI領導層近年最大規模的一次洗牌，也是Discovery Loop能不能重新定義「做研究」這件事的第一步。
什麼是Discovery Loop？
Discovery Loop是一家專注於「自動化科學方法」的AI新創，核心構想是讓AI系統同時執行上千個實驗迴圈：提案、實作、跑結果、評估、再迭代，第一階段先瞄準機器學習研究本身，之後預計擴展到晶片設計、生物醫學、藥物開發與材料科學等領域。
Jeff Dean為什麼離開Google？
Jeff Dean在Google待了近27年，是搜尋基礎架構、TensorFlow到Gemini背後的關鍵推手之一。他與同樣資深的Sanjay Ghemawat，以及Google DeepMind研究員Oriol Vinyals、Quoc Le一起出走，原因是看中「自動化研究迴圈」這個構想的潛力，認為靠新創的速度比在大公司內部推動更快。這次異動同時伴隨Google更大規模的AI組織重整：Demis Hassabis卸下DeepMind執行長職務，轉任董事長暨Alphabet首席科學家，由技術長Koray Kavukcuoglu接手掌管Gemini研發，消息一出Alphabet股價一度下跌約5%。
Discovery Loop怎麼運作？誰投資了它？
根據官方說法，Discovery Loop會用前沿AI模型結合大規模運算基礎設施，讓系統能快速提出實驗、實際執行、學習評估結果，並且是「大量平行」而非一次一個地跑。目前已知的支持者包括：
- Khosla Ventures與Radical Ventures領投，Radical合夥人Jordan Jacobs加入董事會
- Google以創始投資人身分加入，並擔任雲端運算合作夥伴
- 具體募資金額與估值目前未對外公開
小克怎麼看？
老實說，「AI自動做科學研究」這句話這幾年被講到爛，但Discovery Loop的不同之處在於團隊背景——這些人親手打造過Google的研究基礎設施，知道瓶頸卡在哪。不過目前公司連產品原型、時程表都沒公開，一切還停留在願景階段。對關注AI研究自動化的讀者來說，值得先觀望半年到一年，看Discovery Loop能不能真的把「上千個平行實驗」變成可驗證的產出，而不是又一輪募資新聞稿。
好不好用，試了才知道。
🇺🇸 Discovery Loop Explained: Jeff Dean's New AI Startup
Discovery Loop is a new AI startup founded in August 2026 by Jeff Dean, Google's former Chief Scientist, after 27 years at the company. Its mission: automate the entire scientific method — proposing experiments, running them, evaluating results, and iterating — using AI agents operating at a scale and speed no human team could match. This isn't just a job change; it's the biggest shake-up in Google's AI leadership in years, and the first real test of whether Discovery Loop can redefine how research gets done.
What Is Discovery Loop?
Discovery Loop is a startup built around one idea: run thousands of experimental loops in parallel — propose, implement, evaluate, iterate — starting with machine learning research itself before expanding into chip design, biology, drug discovery, and materials science.
Why Did Jeff Dean Leave Google?
Dean spent nearly 27 years at Google, shaping everything from search infrastructure to TensorFlow and Gemini. He left alongside longtime collaborator Sanjay Ghemawat and DeepMind researchers Oriol Vinyals and Quoc Le, betting that a startup could move faster on "automated research loops" than a large company ever could. The exit coincided with a broader Google AI reorg: Demis Hassabis stepped down as DeepMind CEO to become chair and Alphabet's chief scientist, with CTO Koray Kavukcuoglu taking over Gemini development. Alphabet's stock dropped roughly 5% on the news.
How Does Discovery Loop Work — and Who's Backing It?
According to the founders, Discovery Loop will pair frontier AI models with large-scale compute to propose, run, and learn from experiments — running thousands in parallel rather than one at a time. Known backers so far:
- Khosla Ventures and Radical Ventures lead the round, with Radical's Jordan Jacobs joining the board
- Google is a founding investor and will serve as the startup's cloud partner
- Funding amount and valuation remain undisclosed
Kit's Take
"AI that automates science" is a pitch we've heard a hundred times, but what sets Discovery Loop apart is the team — these are the people who built Google's research infrastructure in the first place, so they know exactly where the bottlenecks are. That said, there's no product, prototype, or timeline public yet — it's still all vision. Worth watching over the next 6-12 months to see if "thousands of parallel experiments" turns into verifiable output, or just another funding headline.
好不好用，試了才知道 — works or doesn't, you only know once you've tried it.
