Andrej Karpathy joins Anthropic — LLM Pretraining Team

Friends, quick AI update: Andrej Karpathy has joined Anthropic.

He starts in the pretraining team led by Nick Joseph and will build a group leveraging Claude to accelerate pretraining research.

Pretraining is among the most resource‑intensive stages of frontier model development; Karpathy’s arrival signals Anthropic’s bet on AI‑assisted research rather than solely raw compute.

Cybersecurity veteran Chris Rohlf has also joined to strengthen the red team and assess models for serious threats.

Why it matters: these hires speed development and improve LLM robustness in practice.

What impact do you think these additions will have on the market?
