Dan Hendrycks (born 1994or1995 ^[1] ) is an American machine learning researcher. He serves as the director of the Center for AI Safety, a nonprofit organization based in San Francisco, California.

Early life and education

Hendrycks was raised in a Christian evangelical household in Marshfield, Missouri. ^{[2] [3]} He received a B.S. from the University of Chicago in 2018 and a Ph.D. from the University of California, Berkeley in Computer Science in 2022. ^[4]

Career and research

Hendrycks' research focuses on topics that include machine learning safety, machine ethics, and robustness.

He credits his participation in the effective altruism (EA) movement-linked 80,000 Hours program for his career focus towards AI safety, though denied being an advocate for EA. ^[2]

Hendrycks is the main author of the research paper that introduced the activation function GELU in 2016, ^[5] and of the paper that introduced the language model benchmark MMLU (Massive Multitask Language Understanding) in 2020. ^{[6] [7]}

In February 2022, Hendrycks co-authored recommendations for the US National Institute of Standards and Technology (NIST) to inform the management of risks from artificial intelligence. ^{[8] [9]}

In September 2022, Hendrycks wrote a paper providing a framework for analyzing the impact of AI research on societal risks. ^{[10] [11]} He later published a paper in March 2023 examining how natural selection and competitive pressures could shape the goals of artificial agents. ^{[12] [13] [14]} This was followed by "An Overview of Catastrophic AI Risks", which discusses four categories of risks: malicious use, AI race dynamics, organizational risks, and rogue AI agents. ^{[15] [16]}

Hendrycks is the safety adviser of xAI, an AI startup company founded by Elon Musk in 2023. To avoid any potential conflicts of interest, he receives a symbolic one-dollar salary and holds no company equity. ^{[1] [17]} In November 2024, he also joined Scale AI as an advisor collecting a one-dollar salary. ^[18] Hendrycks is the creator of Humanity's Last Exam, a benchmark for evaluating the capabilities of large language models, which he developed in collaboration with Scale AI. ^{[19] [20]}

In 2024 Hendrycks published a 568 page book entitled "Introduction to AI Safety, Ethics, and Society" based on courseware he had previously developed. ^[21]
