Andrej Karpathy has officially joined Anthropic to spearhead a new team dedicated to accelerating pre-training research, forcing a temporary pause on his education startup, Eureka Labs.
While the industry digests his move to Anthropic, podcast hosts are reflecting on his relentless technical curiosity. On a recent episode of the Lex Fridman Podcast, Jean-Baptiste Kempf noted his ability to pick up complex skills on the fly, remarking, "Karpathy learned assembly because of the tweets, by the way. I just... He start-".
The transition marks a shift from the founder-led autonomy of Eureka Labs back into the high-stakes environment of foundational model development. Observers expect Karpathy to apply the same "assembly-level" intensity to Claude that he previously demonstrated in his open-source advocacy and curriculum building.
