Artificial intelligence researcher and OpenAI co-founding member Andrej Karpathy has joined AI company Anthropic, marking one of the most high-profile talent moves in the sector this year.
Karpathy announced the development in a post on X, saying he was excited to return to research and work on large language models. He will be part of Anthropic’s pre-training team, which focuses on building and training the core foundation models that power its AI assistant Claude.
Karpathy is widely known in the AI community for his work at OpenAI and Tesla, where he previously led AI and computer vision efforts, including contributions to Tesla’s Autopilot system. He is also a respected educator and public voice in AI, with a large following for his technical insights and commentary on machine learning and model development.
At Anthropic, Karpathy is expected to work closely on large-scale model training and help strengthen the company’s research direction as it competes with leading players like OpenAI, Google DeepMind, and Meta in developing advanced AI systems.
The move comes at a time when competition for top AI talent has intensified significantly, with major firms investing heavily in both infrastructure and researchers capable of advancing frontier models. Anthropic has been rapidly expanding its Claude ecosystem and positioning itself as a strong alternative in the enterprise AI and agent-based systems space.
Karpathy said he believes the next few years will be especially important for the evolution of large language models and expressed interest in focusing again on core research and development. He also indicated that he plans to continue his education-focused AI initiatives alongside his new role.
