Andrej Karpathy announced on Tuesday that he has joined Anthropic and will work on the AI company's pretraining team. Karpathy, a founding member of OpenAI and former director of AI at Tesla, stated that he is excited to return to research and development work. He added that he remains passionate about education and plans to resume related projects in the future.
Karpathy helped launch OpenAI as a founding research scientist. He later served as Tesla's AI director before rejoining OpenAI in 2023 and leaving the company again in February 2024. After departing OpenAI, Karpathy founded Eureka Labs, an AI-focused education company.
Anthropic said Karpathy will work on large-scale testing of its Claude models under the pretraining team led by Nick Joseph, a former OpenAI employee who joined Anthropic early. Business Insider reported that interest in Anthropic has increased in 2026 following advancements in its Claude Code and Cowork tools and a dispute with the Trump administration.
The same report noted that Anthropic's rivalry with OpenAI has intensified, with OpenAI CEO Sam Altman recently accusing Anthropic of contributing to hostility directed at him.
