Jeff Dean, Google\u2019s chief scientist, and three other artificial intelligence researchers are leaving the company to form their own start-up, a move that exposes the changing power structure inside Google and shows there is still plenty of venture money willing to back new A.I. ideas.<\/p>\n
Dr. Dean, Google\u2019s 30th employee, is widely regarded as one of the most important figures in the history of the company. He played a key role in creating the global computer network powering its search business and was one of the company\u2019s early leaders in A.I. research.<\/p>\n
His profile inside Google appeared to wane in recent years as other executives, including the co-founder Sergey Brin, asserted control over Google\u2019s all-in bet on A.I. But Dr. Dean remained one of the key engineers driving the creation of the company\u2019s most important technologies.<\/p>\n
His new company, called Discovery Loop, joins a growing list of prominent start-ups chasing a goal that has obsessed Silicon Valley researchers for decades. Dr. Dean and his collaborators want to build A.I. that can improve itself with little or no help from humans.<\/p>\n
They believe that this mind-bending process, called recursive self-improvement<\/a>, can significantly accelerate the development of A.I. The same techniques, they say, can then help design new kinds of computer hardware, discover new drugs, create new materials and speed other forms of scientific discovery.<\/p>\n \u201cWe think there is opportunity for A.I. to more fully automate what has traditionally been a very human-intensive experimental loop,\u201d Dr. Dean said in an interview at his home in Silicon Valley. \u201cYou will get both a higher quantity and a higher quality of experiments, and that will lead to scientific breakthroughs and advances.\u201d<\/p>\n As Google battles to match the A.I. delivered by smaller companies like OpenAI and Anthropic, prominent researchers, lured by a deep pool of venture funding and the chance to run their own companies, continue to leave the tech giant.<\/p>\n Over the past year, Google lost several top researchers<\/a>, including Peter Norvig, who spent 25 years as Google\u2019s head of research, to A.I. start-ups<\/a> such as Recursive Superintelligence, one of the many other companies focused on recursive self-improvement.<\/p>\n \u201cIt is just a very different environment inside a start-up. It is much more fast-paced and focused,\u201d said Tim Rockt\u00e4schel, who left Google earlier this year to help found Recursive Superintelligence. \u201cYou are a smaller team. There is much less bureaucracy and politics.\u201d<\/p>\n Dr. Dean, 58, expected to leave Google in the next few days for his new job as the start-up\u2019s chief executive. He will be joined by Sanjay Ghemawat, his close collaborator of more than two decades; Quoc Le, whose research helped inspire the creation of today\u2019s A.I. chatbots<\/a>; and Oriol Vinyals, who had overseen the design of Google\u2019s chatbot technologies with Dr. Dean since 2023.<\/p>\n The new company is backed by seed funding from Radical Ventures, Khosla Ventures and several Silicon Valley investors, including Google\u2019s parent company. The departing Google researchers declined to reveal how much money their start-up has raised, but they appear to be leaving Google on good terms. Google\u2019s parent company, Alphabet, has also agreed to provide the computing power they need to build their A.I. technologies for at least the next year, Dr. Dean said.<\/p>\n \u201cOver 27 years, Jeff and Sanjay helped to drive some of the most significant technology transitions, from our early search infrastructure to the neural networks that helped create the modern A.I. era,\u201d Google\u2019s chief executive, Sundar Pichai, said in a statement. \u201cOn a personal note, it\u2019s been a privilege to work alongside Jeff and Sanjay.\u201d<\/p>\n Google will collaborate with the new start-up, Mr. Pichai said.<\/p>\n Dr. Vinyals said he believed it was important to have the freedom to shape their own company. \u201cHaving extreme focus is very powerful,\u201d he said in an interview. \u201cThe ultimate form of extreme focus is when it is the only thing that matters \u2014 when it aligns with the mission of the company.\u201d<\/p>\n Dr. Dean joined Google in 1999. Along with Dr. Ghemawat and others, he designed the enormously complex software systems<\/a> that allowed Google\u2019s search engine to reliably and efficiently respond to search queries from billions of people across the world.<\/p>\n With names like MapReduce, BigTable and Spanner, these systems served as a template for the rest of the industry, showing companies like Amazon and Meta how to juggle traffic from a global audience. Dr. Dean and Dr. Ghemawat are the only two Google employees to be named a \u201csenior fellow,\u201d the company\u2019s highest technical honor.<\/p>\n In 2011, Dr. Dean led the creation of Google Brain, an A.I. research lab that touched off an industrywide push toward A.I<\/a>. The lab\u2019s early hires included Dr. Le and Dr. Vinyals, who helped develop a language translation technology, later called Google Translate, that proved to be a significant milestone in the race to A.I.<\/a><\/p>\n But after Google\u2019s team of researchers, including Dr. Le and Dr. Vinyals, helped to pioneer the technology<\/a> that drives today\u2019s chatbots, the company was slow to realize its potential. Months after OpenAI released ChatGPT, jump-starting the A.I. boom in late 2022, the tech giant merged Google Brain with DeepMind, its London-based research lab.<\/p>\n The DeepMind founder Demis Hassabis led the new lab, called Google DeepMind, while Dr. Dean and Dr. Vinyals oversaw the design of Gemini, the company\u2019s answer to ChatGPT. In 2024, a third pioneering researcher, Noam Shazeer, joined them in this role, before departing the company less than two months ago to join OpenAI.<\/p>\n When Mr. Brin returned to Google, the company accelerated its A.I. work, but its technologies, by some measurements, continue to trail those produced by U.S. start-ups like Anthropic and OpenAI \u2014 or even Chinese companies like Moonshot and Z.ai<\/a>.<\/p>\n As Google has begun to work more closely with the Trump administration, Dr. Dean has been among a number of employees to push back against the government.<\/p>\n Earlier this year, he was one of the few Silicon Valley executives to speak out when federal agents killed protesters in Minneapolis, calling the shootings \u201cabsolutely shameful<\/a>.\u201d He was also among the Google employees who filed a legal brief in support of a suit that Anthropic filed against the Defense Department<\/a>, after the Pentagon barred government agencies from using the start-up\u2019s technologies.<\/p>\n Dr. Dean said that unlike Google, his new company would operate as a public benefit corporation, or P.B.C., which is a for-profit corporation designed to create public and social good. Anthropic, OpenAI and other A.I. companies have adopted a similar structure.<\/p>\n \u201cThere is a lot of good that can be done in the world if we can distribute scientific discoveries broadly,\u201d he said. \u201cWe might make decisions that are not necessarily in the company\u2019s purist financial interests.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Jeff Dean, Google\u2019s chief scientist, and three other artificial intelligence researchers are leaving the company to form their…\n","protected":false},"author":2,"featured_media":130512,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[25,1555,16950,5044,16952,65298,65293,132,7543,1153,16951,65294,65297,65295,63736,1585,65296],"class_list":["post-130511","post","type-post","status-publish","format-standard","has-post-thumbnail","category-google","tag-artificial-intelligence","tag-computers-and-the-internet","tag-dean","tag-deepmind","tag-deepmind-technologies-ltd","tag-discovery-loop","tag-ghemawat","tag-google","tag-google-deepmind","tag-google-inc","tag-jeff-1968","tag-le","tag-oriol","tag-quoc","tag-sanjay","tag-start-ups","tag-vinyals"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/130511","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/comments?post=130511"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/130511\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/130512"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=130511"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=130511"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=130511"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
