OpenAI co-founder Andrej Karpathy joins Anthropic’s pre-training team
# OpenAI Co-Founder Joins Anthropic to Lead AI Training Andrej Karpathy, a key figure at OpenAI, is moving to Anthropic to lead the team responsible for teaching AI models like Claude how to understand and respond to questions. This work—called pre-training—is both extremely expensive and crucial to building powerful AI systems, so landing someone of Karpathy's experience is a significant win for Anthropic in the competitive race to develop better AI.
Pre-training is responsible for the large-scale training runs that give Claude its core knowledge and capabilities, according to the company. It's also one of the most expensive, compute-intensive phases of building a frontier model.
