Dario Amodei (born 1983) is an American artificial intelligence researcher, entrepreneur, and the co-founder and Chief Executive Officer of Anthropic, an AI research and deployment company. Widely recognized as a central figure in the field of generative artificial intelligence and AI safety, Amodei has been instrumental in the development of large language models and the advancement of techniques to align AI systems with human values. Born in San Francisco, California, Amodei was raised in the Bay Area and attended Lowell High School. His early academic interests centered on physics and fundamental scientific inquiry. He began his undergraduate studies at the California Institute of Technology (Caltech) before transferring to Stanford University, where he earned a Bachelor of Science degree in physics. His academic path continued at Princeton University, where he received a Ph.D. in biophysics. His doctoral research, which focused on the electrophysiology of neural circuits, provided a technical foundation for his later work in computational intelligence. Following his graduate studies, he completed a postdoctoral fellowship at the Stanford University School of Medicine, where he applied computational methods to biomedical data analysis. Amodei’s career in the technology industry began in earnest as he transitioned from academic research to machine learning. He held positions at Baidu, working in the company’s AI division, and subsequently joined the Google Brain team as a senior research scientist. In these roles, he focused on deep learning and neural network reliability. In 2016, Amodei joined OpenAI, where he ascended to the role of Vice President of Research. During his tenure at OpenAI, he played a pivotal role in the development and scaling of the organization’s most significant models, including GPT-2 and GPT-3. Notably, he is a co-inventor of Reinforcement Learning from Human Feedback (RLHF), a training methodology that has become a standard approach for improving the steerability and safety of large language models. In 2021, driven by concerns regarding the long-term safety and social implications of rapid AI advancement, Amodei left OpenAI alongside his sister, Daniela Amodei, and several other former colleagues to co-found Anthropic. As a public benefit corporation, Anthropic was established with a mission to prioritize AI safety and "Constitutional AI"—a method of training models to adhere to a specific set of rules or principles. Under Amodei’s leadership, the company developed the Claude series of large language models, which have been distinguished in the industry for their emphasis on reliability, transparency, and safety. Throughout his career, Amodei has emerged as a prominent, often vocal participant in public discourse regarding the governance of artificial intelligence. He frequently advocates for proactive AI safety measures, calling for both robust technical research and thoughtful policy engagement to mitigate the risks associated with increasingly capable systems. His influence extends beyond the laboratory; he is widely cited as one of the most impactful leaders in the AI industry, balancing the commercial success of Anthropic with a persistent focus on long-term technological risks and the ethical alignment of transformative technologies.
