Karpathy joins Anthropic: 700 experiments in 2 days, knowledge graphs boost his loop
blaizedsouza · x · 2026-09-06
A thread rounds up what's checkable about Andrej Karpathy's first 14 weeks at Anthropic: the viral "1000x better with graph engineering" claim has no traceable source, but Anthropic's own knowledge-graph cookbook is public, and Karpathy's autoresearch loop ran 700 experiments in 2 days, surfacing 20 optimizations on its own. The author wired the graph approach into his own setup and says Claude skipped stock answers on the very first reply. The quoted article covers building loops, graphs and dynamic workflows in the order you should actually build them.
