'''Ilya Sutskever''' [[Fellow of the Royal Society|FRS]] (born 1986) is an Israeli-Canadian computer scientist and artificial intelligence researcher who has made foundational contributions to [[deep learning]]. He is best known as a co-founder and former Chief Scientist of [[OpenAI]], where he played a central role in developing [[GPT-3]] and [[ChatGPT]], and for his pivotal involvement in the 2023 attempt to remove [[Sam Altman]] as OpenAI's CEO.<ref name="wiki">{{cite web |url=https://en.wikipedia.org/wiki/Ilya_Sutskever |title=Ilya Sutskever - Wikipedia |access-date=December 4, 2025}}</ref>

With [[Alex Krizhevsky]] and his doctoral advisor [[Geoffrey Hinton]], Sutskever co-invented [[AlexNet]], the [[convolutional neural network]] that won the [[ImageNet]] Large Scale Visual Recognition Challenge in 2012 and is credited with igniting the modern deep learning revolution.<ref name="wiki"/>

In June 2024, Sutskever founded [[Safe Superintelligence Inc.]] (SSI), a company focused exclusively on developing safe [[superintelligence|superintelligent]] AI systems. As of 2025, the company has raised over $3 billion and reached a valuation of approximately $32 billion.<ref name="wiki"/>

== Early life ==

Sutskever was born in 1986 into a Jewish family in [[Nizhny Novgorod|Gorky]] (now Nizhny Novgorod), [[Russian SFSR]], in the [[Soviet Union]]. At age five, his family made [[aliyah]] (immigrated to Israel) and settled in [[Jerusalem]], where he lived until age 16.<ref name="wiki"/>

He first encountered a computer at age five and became captivated by the possibilities of computing.<ref name="pressfarm">{{cite web |url=https://press.farm/ilya-sutskevers-early-life-education-career-ai/ |title=Ilya Sutskever's Early Life, Education & Career in AI |publisher=Press Farm |access-date=December 4, 2025}}</ref>

While still in middle school in Israel, Sutskever attended courses at the [[Open University of Israel]] from 2000 to 2002, demonstrating exceptional self-driven learning abilities.<ref name="wiki"/>

When Sutskever was 16, his family immigrated to Canada.<ref name="wiki"/>

== Education ==

At the [[University of Toronto]], Sutskever earned his Bachelor of Science degree in mathematics in 2005, his Master of Science degree in computer science in 2007, and his [[Doctor of Philosophy|PhD]] in computer science in 2013 under the supervision of [[Geoffrey Hinton]], a pioneer of deep learning research.<ref name="wiki"/>

Sutskever has recalled that when he arrived at the University of Toronto as an undergraduate, he knew little about AI despite his fascination with computers. His introduction to neural networks came through his relationship with Hinton, who assigned him an early research project to improve the [[Stochastic Neighbor Embedding]] algorithm. Sutskever's success on this project initiated their long collaboration.<ref name="globeandmail">{{cite web |url=https://www.theglobeandmail.com/business/article-how-openais-ilya-sutskever-went-from-university-of-toronto-ai-whiz-to/ |title=Who is Ilya Sutskever, the OpenAI board member who led the ouster of Sam Altman - then regretted it? |publisher=The Globe and Mail |access-date=December 4, 2025}}</ref>

Fellow University of Toronto researcher Ruslan Salakhutdinov observed: "We all were working on this new deep learning sort of field, which was not very popular. Out of all of us, Ilya was the biggest believer in neural networks."<ref name="globeandmail"/>

In 2012, Sutskever briefly conducted postdoctoral research with [[Andrew Ng]] at [[Stanford University]]. He then returned to Toronto and joined DNNResearch, a spinoff company created by Hinton that was subsequently acquired by [[Google]].<ref name="wiki"/>

== Career ==

=== AlexNet and Google ===

In 2012, Sutskever, along with [[Alex Krizhevsky]] and [[Geoffrey Hinton]], developed [[AlexNet]], a deep convolutional neural network that won the [[ImageNet Large Scale Visual Recognition Challenge]] (ILSVRC) by a substantial margin. This victory is widely regarded as the breakthrough that launched the modern era of deep learning and established neural networks as the dominant approach in computer vision.<ref name="wiki"/>

Following Google's acquisition of DNNResearch in 2013, Sutskever worked at [[Google Brain]], where he continued his research on neural networks and sequence-to-sequence learning.<ref name="wiki"/>

=== OpenAI ===

In December 2015, Sutskever left Google to become a co-founder and Chief Scientist of [[OpenAI]], the artificial intelligence research laboratory established by [[Sam Altman]], [[Elon Musk]], and others. At OpenAI, he led research efforts that produced many of the organization's most significant achievements.<ref name="wiki"/>

Sutskever oversaw the development of increasingly capable [[large language model]]s, including [[GPT-2]], [[GPT-3]], [[GPT-4]], and [[ChatGPT]]. His team also pioneered work on [[reinforcement learning from human feedback]] (RLHF), which became central to training AI systems to be helpful and harmless.<ref name="wiki"/>

He also led OpenAI's Superalignment team, which focused on the challenge of ensuring that superintelligent AI systems remain aligned with human values and intentions.<ref name="time">{{cite web |url=https://time.com/6978195/ilya-sutskever-leaves-open-ai/ |title=Ilya Sutskever, Co-Founder and Chief Scientist, Leaves OpenAI |publisher=Time |date=May 14, 2024 |access-date=December 4, 2025}}</ref>

=== Sam Altman firing controversy ===

On November 17, 2023, OpenAI's board of directors - which included Sutskever - abruptly fired CEO [[Sam Altman]], citing a lack of confidence in his leadership and stating that he was not "consistently candid in his communications."<ref name="biography">{{cite web |url=https://www.biography.com/business-leaders/a65204556/openai-sam-altman-ilya-sutskever |title=OpenAI's CEO Crisis Pitted Sam Altman Against Ilya Sutskever |publisher=Biography |access-date=December 4, 2025}}</ref>

According to multiple reports, Sutskever was instrumental in Altman's removal. He had authored detailed memos to OpenAI's independent directors accusing Altman of "a consistent pattern of lying."<ref name="futurism">{{cite web |url=https://futurism.com/sam-altman-firing-reason-book |title=This Appears to Be Why Sam Altman Actually Got Fired by OpenAI |publisher=Futurism |access-date=December 4, 2025}}</ref>

The tensions reportedly stemmed from multiple sources:
* Sutskever opposed Altman's efforts to seek billions from Middle Eastern sovereign wealth funds for AI chip development
* Altman had reduced Sutskever's role within the company in October 2023
* Fundamental disagreements existed about how rapidly to develop AI technology versus prioritizing safety research<ref name="futurism"/>

The firing triggered chaos at OpenAI. More than 500 of the company's approximately 700 employees threatened to resign in an open letter if Sutskever and the other board members did not step down, with many threatening to follow Altman to a new AI unit at [[Microsoft]].<ref name="axios">{{cite web |url=https://www.axios.com/2023/11/20/sam-altman-fired-openai-board-illya-sutsever-regrets |title=OpenAI chief scientist says he regrets board's firing of Sam Altman |publisher=Axios |date=November 20, 2023 |access-date=December 4, 2025}}</ref>

Within days, Sutskever publicly expressed regret, posting on social media: "I deeply regret my participation in the board's actions."<ref name="fortune">{{cite web |url=https://fortune.com/2023/11/20/ilya-sutskever-openai-cofounder-deeply-regrets-resign/ |title=Ilya Sutskever, the OpenAI cofounder who helped oust CEO Sam Altman, says he "deeply regrets" his role |publisher=Fortune |date=November 20, 2023 |access-date=December 4, 2025}}</ref>

In later testimony, Sutskever revealed that the board had explored merging OpenAI with rival [[Anthropic]] immediately after Altman's removal - a proposal Sutskever opposed. "I really did not want OpenAI to merge with Anthropic," he testified.<ref name="officechai">{{cite web |url=https://officechai.com/ai/openais-board-had-considered-merging-with-anthropic-after-sam-altmans-ouster-in-2023-ilya-sutskever/ |title=OpenAI's Board Had Considered Merging With Anthropic After Sam Altman's Ouster In 2023 |publisher=Office Chai |access-date=December 4, 2025}}</ref>

Altman was reinstated as CEO five days later on November 22, 2023, and the board was reconstituted without the members who had orchestrated his removal.<ref name="wiki"/>

=== Departure from OpenAI ===

In May 2024, Sutskever announced his departure from OpenAI after nearly a decade with the company. Reports indicated that he had been effectively marginalized following the failed attempt to remove Altman, and had not returned to work after November 2023.<ref name="techcrunch">{{cite web |url=https://techcrunch.com/2024/05/14/ilya-sutskever-openai-co-founder-and-longtime-chief-scientist-departs/ |title=Ilya Sutskever, OpenAI co-founder and longtime chief scientist, departs |publisher=TechCrunch |date=May 14, 2024 |access-date=December 4, 2025}}</ref>

The Superalignment team Sutskever had led was dissolved following his departure. [[Jan Leike]], the team's other co-leader, also resigned, citing an "erosion of safety and trust in OpenAI's leadership."<ref name="bloomberg">{{cite web |url=https://www.bloomberg.com/news/articles/2024-05-17/openai-dissolves-key-safety-team-after-chief-scientist-ilya-sutskever-s-exit |title=OpenAI Dissolves Key Safety Team After Chief Scientist Ilya Sutskever's Exit |publisher=Bloomberg |date=May 17, 2024 |access-date=December 4, 2025}}</ref>

=== Safe Superintelligence Inc. ===

In June 2024, Sutskever founded [[Safe Superintelligence Inc.]] (SSI), a new AI company focused exclusively on developing safe superintelligent systems. He co-founded the company with Daniel Gross and Daniel Levy, with offices in [[Palo Alto, California|Palo Alto]] and [[Tel Aviv]].<ref name="wiki"/>

In contrast to OpenAI's approach of releasing commercial products, Sutskever stated that SSI's "first product will be the safe superintelligence, and it will not do anything else up until then."<ref name="wiki"/>

The company has attracted significant investor interest:
* September 2024: Raised $1 billion from [[Andreessen Horowitz]], [[Sequoia Capital]], [[DST Global]], and SV Angel<ref name="wiki"/>
* March 2025: Raised an additional $2 billion, reaching a reported valuation of $32 billion<ref name="calcalis">{{cite web |url=https://www.calcalistech.com/ctechnews/article/sjp2u5oj11e |title=Ilya Sutskever breaks silence on OpenAI departure: "I had a big new vision" |publisher=Calcalist |access-date=December 4, 2025}}</ref>
