Dario Amodei (born 1983) is an American artificial intelligence researcher and entrepreneur who serves as the co-founder and chief executive officer of Anthropic, the AI safety company behind the large language model series Claude. Before founding Anthropic, Amodei held the position of vice president of research at OpenAI, one of the most prominent AI research laboratories in the world. His career has been shaped by a dual concern: advancing the capabilities of AI systems while simultaneously working to ensure their safety and alignment with human values. Amodei has become one of the most prominent voices in public debates about both the transformative potential and the existential risks posed by advanced AI. He has testified before the United States Senate on the dangers of AI-enabled bioweapons and has written extensively on subjects ranging from AI safety policy to the potential for AI to drive dramatic improvements in science, medicine, and human welfare. In 2025, he was named to the Time 100 list of the most influential people in the world. He has expressed concern about what he describes as the "overnight" and accidental concentration of power in the hands of individuals leading AI companies, including himself.

Early Life

Dario Amodei was born in 1983 in San Francisco, California. He grew up in the San Francisco Bay Area and attended Lowell High School, one of the oldest public high schools in the city, known for its academically rigorous curriculum. His sister, Daniela Amodei, would later become his co-founder at Anthropic, where she serves as president.

Amodei developed an early interest in the sciences, particularly in understanding complex systems. His academic trajectory led him to pursue graduate work at the intersection of physics, neuroscience, and computational methods, reflecting an interdisciplinary approach that would later define his work in artificial intelligence. His educational background in biophysics and computational neuroscience provided him with a deep understanding of how biological neural circuits function—knowledge that informed his subsequent transition into the field of artificial neural networks and machine learning.

Education

Amodei earned his Ph.D. from Princeton University in 2011. His doctoral dissertation, titled "Network-Scale Electrophysiology: Measuring and Understanding the Collective Behavior of Neural Circuits," examined how large populations of neurons operate collectively, an area of research with direct conceptual parallels to the artificial neural networks that underpin modern AI systems. His doctoral advisors were Michael J. Berry and William Bialek, both prominent researchers in theoretical biophysics and neuroscience.

Amodei was a recipient of a fellowship from the Fannie and John Hertz Foundation, a prestigious award given to graduate students in the applied physical, biological, and engineering sciences who show exceptional promise for innovative research. The Hertz Fellowship is highly competitive, and its recipients have included numerous notable scientists and technology leaders.

Career

Early Research

Following his doctoral work at Princeton, Amodei pursued research that bridged computational neuroscience and machine learning. His academic publications, spanning topics in neural electrophysiology and computational methods, are indexed in major scientific databases including Scopus and Google Scholar. His transition from neuroscience to artificial intelligence reflected a broader trend in the field, as researchers trained in understanding biological intelligence increasingly turned their attention to building artificial systems capable of complex reasoning and learning.

OpenAI

Amodei joined OpenAI, the San Francisco-based AI research organization, where he rose to the position of vice president of research. At OpenAI, he played a significant role in the organization's research agenda, contributing to efforts in scaling AI models and studying the safety properties of large language models.

During his tenure at OpenAI, Amodei was closely involved with the development and scaling of GPT series models and research into AI alignment—the challenge of ensuring that AI systems behave in ways consistent with human intentions and values. His time at OpenAI placed him at the center of some of the most consequential technical developments in modern AI, as the organization's work on large language models helped catalyze an industry-wide race to develop increasingly capable AI systems.

However, Amodei and several of his colleagues at OpenAI grew concerned about the organization's direction, particularly regarding its approach to safety research and its evolving corporate governance structure. These concerns ultimately led Amodei, along with his sister Daniela and several other senior researchers, to depart OpenAI and establish a new organization with a different approach to AI development and safety.

During the 2023 OpenAI leadership crisis, in which OpenAI's board of directors briefly removed CEO Sam Altman, OpenAI's board reportedly approached Amodei about potentially returning to lead OpenAI or exploring a merger between OpenAI and Anthropic. Amodei declined these overtures.

Founding of Anthropic

In 2021, Amodei co-founded Anthropic alongside his sister Daniela Amodei and a group of former OpenAI researchers. The company was established with a stated mission of building AI systems that are safe, beneficial, and understandable. Anthropic adopted a public benefit corporation structure, a legal designation intended to balance the pursuit of profit with a broader commitment to social good.

Anthropic distinguished itself from competitors through its emphasis on AI safety research as a core part of its business strategy rather than an adjunct to capability development. The company introduced the concept of "constitutional AI," a technique for training AI systems to follow a set of principles designed to make their outputs more helpful, harmless, and honest. This approach represented a departure from conventional reinforcement learning from human feedback (RLHF) methods and drew significant attention from the AI research community.

Under Amodei's leadership, Anthropic developed and released the Claude series of large language models, which became one of the principal competitors to OpenAI's ChatGPT and Google's Gemini in the commercial AI market. The company attracted substantial investment, raising billions of dollars in funding from investors including Google and Spark Capital, among others.

Public Advocacy and Policy Engagement

Amodei has emerged as one of the most visible figures in public discourse about the future of artificial intelligence, offering assessments of both the technology's potential benefits and its risks that tend to emphasize the magnitude of both.

In July 2023, Amodei testified before members of the United States Senate, warning of the potential for AI systems to be used in the development of biological weapons. He described scenarios in which advanced AI could lower the barriers for non-state actors seeking to create dangerous pathogens, a warning that contributed to growing congressional attention to AI regulation.

In interviews and public appearances, Amodei has discussed what he characterizes as a range of AI risks spanning different time horizons. In a 2023 interview with Fortune, he outlined short-term risks such as misinformation and deepfakes, medium-term risks related to economic disruption and labor displacement, and long-term risks including the possibility that superintelligent AI systems could pose existential threats to humanity if not properly aligned with human values.

In a July 2023 episode of The New York Times podcast, Amodei discussed what he described as the "paradoxes" of AI safety—the tension between developing increasingly powerful AI systems and ensuring that those systems remain under meaningful human control.

"Machines of Loving Grace"

In October 2024, Amodei published a lengthy essay on his personal website titled "Machines of Loving Grace," in which he laid out a detailed and optimistic vision of how advanced AI could transform multiple domains of human life, including biology and medicine, neuroscience, economic development, and governance. The essay's title is a reference to Richard Brautigan's 1967 poem "All Watched Over by Machines of Loving Grace."

In the essay, Amodei argued that if AI development proceeds well—a conditional he repeatedly emphasized—the technology could compress decades of scientific progress into a few years, leading to breakthroughs in curing diseases, extending human lifespans, and lifting developing nations out of poverty. He discussed the potential for AI to accelerate drug discovery, improve diagnostics, and transform clinical trials, while also acknowledging the significant challenges in ensuring these benefits are broadly distributed rather than concentrated among wealthy nations and individuals.

The essay drew significant attention in both the technology industry and the broader media. Fast Company described it as "a smart look at our AI future" that stood out for its specificity and willingness to engage with concrete scenarios rather than vague generalities.

Views on AI Governance and Geopolitics

Amodei is a proponent of what he describes as an "entente" strategy for AI governance, in which a coalition of democratic nations would develop and deploy advanced AI systems—including in military applications—to achieve a decisive strategic advantage over authoritarian adversaries. Under this framework, the benefits of AI would be shared with cooperating nations, creating incentives for broader international participation in a rules-based AI governance order. This position reflects Amodei's view that advanced AI will inevitably be developed and that the key question is which values and governance structures will shape its deployment.

In February 2026, Amodei publicly expressed discomfort with the concentration of power that has resulted from the rapid development of AI technology, noting that there is a "certain randomness" to how individuals leading powerful AI companies end up in their positions. He described this concentration as both "overnight" and "accidental," suggesting that the governance structures surrounding AI development have not kept pace with the technology's growing influence.

Personal Life

Amodei's sister, Daniela Amodei, is the co-founder and president of Anthropic. The siblings' close professional collaboration has been a defining feature of Anthropic's leadership structure, with Dario focusing primarily on research and technical strategy and Daniela overseeing business operations and organizational development.

Amodei maintains a personal website at darioamodei.com, where he publishes essays and writings on AI policy, safety, and the future of the technology. He has been described in profiles as someone who approaches AI development with a combination of intellectual rigor drawn from his scientific training and a deep concern about the societal implications of the technology he is helping to build.

Recognition

In 2023, Amodei was included on Time magazine's inaugural TIME100 AI list, which recognized the 100 most influential people in artificial intelligence. Princeton University noted that six of its alumni and faculty were included on the list.

In 2025, Amodei was named to the Time 100 list, Time magazine's annual compilation of the 100 most influential people in the world, reflecting his growing prominence not only within the technology industry but in broader global affairs.

Amodei is a fellow of the Fannie and John Hertz Foundation, which supported his doctoral research at Princeton. His doctoral thesis remains accessible through Princeton University's DataSpace repository.

His research contributions are documented across multiple academic databases, including the Association for Computing Machinery (ACM) Digital Library, Scopus, zbMATH, and Google Scholar.

Legacy

Amodei's career trajectory—from computational neuroscientist to vice president of research at OpenAI to co-founder and CEO of Anthropic—has placed him at the center of the development of large language models and the broader debate over AI safety and governance. His decision to leave OpenAI and establish Anthropic as a safety-focused competitor has been interpreted as one of the defining moments in the institutional history of the AI industry, reflecting a philosophical divide over how to balance capability advancement with safety research.

Through Anthropic, Amodei has championed the idea that safety research and commercial AI development are not inherently in tension—that companies can pursue frontier AI capabilities while simultaneously investing in techniques to make those systems more controllable and aligned with human values. The company's constitutional AI approach and its emphasis on interpretability research have influenced how the broader industry thinks about responsible AI development.

Amodei's public writings and policy engagements have contributed to shaping the terms of the debate over AI regulation. His testimony before the U.S. Senate on AI-enabled bioweapons risks helped elevate biosecurity as a central concern in AI policy discussions. His "Machines of Loving Grace" essay offered one of the more detailed public visions from an industry leader of how AI could drive positive outcomes across multiple domains, while his concurrent warnings about catastrophic risks have underscored the stakes involved in AI development.

His expressed concern about the accidental concentration of power in the hands of AI company leaders—including himself—has added a self-reflective dimension to the governance debate that is relatively unusual among technology executives.
