Andrej Karpathy joins Anthropic

The title says Andrej Karpathy joins Anthropic; the post only includes an X link, a Hacker News comments link, 46 points, and 3 comments, and does not disclose his role, team, or start date.

Why it matters: HKR-H and HKR-R pass: Karpathy moving to Anthropic is a high-signal talent story for Claude watchers and AI-lab hiring. HKR-K is thin because the post gives no role, team, or start date, so it stays in the 78–84 band.
