Summary

Andrej Karpathy Joins Anthropic

Andrej Karpathy has joined Anthropic as a researcher, continuing work on his open-source AI research project. According to reporting, Karpathy will focus on RSI (Reinforcement Self-Improvement) and auto-research, the autonomous research framework he has been developing publicly.

The move reads as an effective acquihire of his open-source project. Rather than Anthropic licensing or acquiring standalone technology, the company is bringing Karpathy on to advance the work within its own research organization.

Karpathy has cycled through OpenAI, Tesla, and back to OpenAI over his career — a pattern one host characterizes as a "world tour of AI labs." He had also been exploring an education-focused project, though those details remain unclear and may not factor into his work at Anthropic.
