   Karpathy launches HackerTube, a Claude Code-built video recommender

   cnBeta reports that Andrej Karpathy released HackerTube, a weekend project that uses recommendations found in two decades of Hacker News comments to assemble a video library. Karpathy says Claude Code, running Claude Opus 5.5 with medium reasoning effort, analyzed 43 million comments, selected 6,454 repeatedly recommended videos, and assisted with development and deployment. He also says the project took about two hours, while HackerTube requires no account and stores usage state in the local browser session.
