TL;DRAndrej Karpathy, one of OpenAI’s original 11 co-founders, has joined Anthropic’s pre-training team. He will build a new group that uses Claude itself to accelerate the most expensive phase of frontier model development.
Andrej Karpathy, one of the original co-founders of OpenAI and among the most recognised AI researchers in the world, announced on Monday that he has joined Anthropic. The move is a significant talent coup for the Claude maker as it races to stay at the frontier of large language model development.

Karpathy is joining Anthropic’s pre-training team, led by Nick Joseph, where he will build a brand-new group focused on a strikingly recursive goal: using Claude itself to accelerate pre-training research. Pre-training, the massive compute-intensive phase that gives a frontier model its core knowledge and capabilities, is the single most expensive part of building systems like Claude. Finding ways to make that process faster and more efficient could reshape the economics of the entire AI industry.
In an X post that racked up 13.6 million views, Karpathy wrote that he believes “the next few years at the frontier of LLMs will be especially formative.” He added that he remains “deeply passionate about education” and plans to resume that work in time.
