Question: Who is Jared Kaplan at Anthropic?

Answer:

Jared Kaplan — Co-Founder & Chief Science Officer at Anthropic

Background & Education

Jared Daniel Kaplan is a theoretical physicist and AI researcher. He holds a bachelor’s degree in physics and mathematics from Stanford University and a PhD in physics from Harvard University, where his doctoral thesis focused on aspects of holography, advised by Nima Arkani-Hamed.

He spent the first 15 years of his career as a theoretical physicist in academia. Prior to co-founding Anthropic, he was instrumental in building GPT-3 and Codex at OpenAI.

Role at Anthropic

Jared Kaplan is the Chief Science Officer and Co-Founder of Anthropic, an AI lab whose research and products prioritize safety at the frontier. As a public benefit corporation, Anthropic is dedicated to building AI systems that benefit humanity.

In October 2024, Anthropic announced that Kaplan would also serve as the company’s “Responsible Scaling Officer”, overseeing its Responsible Scaling Policy (RSP). In this role, he determines the safety assessments and precautions to adopt before model release.

Key Contributions to AI

1. Scaling Laws Kaplan’s research on scaling laws revolutionized the AI industry by providing a framework for understanding and predicting the behavior of advanced AI systems, guiding resource allocation, and shaping the development of transformative technologies. His landmark 2020 paper, Scaling Laws for Neural Language Models, established that AI model performance improves predictably with increased size, data, and compute.

2. Constitutional AI Kaplan also helped pioneer Constitutional AI, an approach to AI development that aims to create AI systems constrained by and aligned with a set of predetermined principles and values.

3. GPT-3 & Large Language Models While at OpenAI, he co-authored Language Models are Few-Shot Learners (2020), one of the foundational papers behind GPT-3.

Academic Work

Kaplan has been an associate professor at Johns Hopkins University’s Department of Physics & Astronomy since 2012. His academic research interests span quantum gravity, holography (AdS/CFT), conformal field theory, and related topics in particle physics and cosmology.

Net Worth & Recognition

As of 2026, Forbes estimated Kaplan’s net worth at $3.7 billion. He has received notable fellowships and awards including a Hertz Fellowship, a Sloan Research Fellowship, and an NSF CAREER award.

In summary, Jared Kaplan is one of the most influential figures in modern AI — both as a scientist who laid the theoretical groundwork for how large language models scale, and as a leader shaping AI safety practices at one of the world’s top AI labs.
