Anthropic Hires Former OpenAI Co-Founder Karpathy for Pre-Training Research
AI researcher Andrej Karpathy joins Anthropic to lead a new team using Claude to accelerate large-scale model pre-training. The high-profile hire signals a strategic shift toward AI-assisted research to stay competitive in the frontier model race.
Andrej Karpathy officially joins Anthropic this week to work on the pre-training team under lead Nick Joseph. Pre-training represents the most compute-intensive phase of building frontier models, providing Claude with its core knowledge and capabilities. Karpathy expresses strong excitement about returning to hands-on research and development during what he considers a highly formative period for large language models.
Anthropic tasks Karpathy with building a specialized team focused on using Claude to accelerate pre-training research. Because Karpathy possesses a rare ability to bridge LLM theory and large-scale training practice, this move highlights Anthropic's belief that AI-assisted research is the key to competing with rivals like OpenAI and Google. This strategic hire emphasizes smarter research methods over relying purely on raw computing power.
Karpathy brings a impressive resume to Anthropic, including co-founding OpenAI and leading Tesla's Autopilot and Full Self-Driving programs. He briefly returned to OpenAI in 2023 before departing to found Eureka Labs, an AI education startup whose current status remains unclear. Despite his new role, Karpathy states he remains deeply passionate about education and plans to resume his educational work in the future.
