Andrej Karpathy Joins Anthropic

Andrej Karpathy, a prominent AI researcher known for his work at Tesla and OpenAI, has joined Anthropic. After leaving Tesla in 2022, Karpathy became an influential public educator in AI. He announced his move to Anthropic on X (formerly Twitter) on May 19 (2026), expressing his excitement to return to R&D, believing the next few years at the frontier of LLMs (Large Language Models) will be especially formative.

Strengthening LLM Pre-training and AI Research

At Anthropic, Karpathy will focus on pre-training under team lead Nick Joseph. Pre-training is a large-scale training process crucial for building the core knowledge and capabilities of LLMs like 'Claude,' and it requires significant computational resources. By bringing Karpathy on board, Anthropic aims to strengthen its AI research capabilities, signaling a strategy to stay competitive with OpenAI and Google through AI-assisted research rather than pure compute power. In a related move, Anthropic also recruited Chris Rohlf, a cybersecurity veteran, to its 'frontier red team' to stress-test advanced AI models against severe threats, demonstrating a multi-faceted approach to AI development.
