Karpathy ships HackerTube in ~2 hours with Claude Opus 5.5
Andrej Karpathy released HackerTube on October 31, a YouTube‑style site seeded with 6,454 videos pulled from 40,000 Hacker News comments that recommend videos. The content spans 2007‑2026 across 150 topics.
Key points
- Karpathy built HackerTube from 6,454 videos in about two hours
- Claude Opus 5.5 drove the build, Claude Sonnet filtered comments
- Karpathy’s manual work was limited to a Google Cloud key, VPS, and domain
Karpathy says the build took about two hours. Claude Opus 5.5 performed the bulk of the work, while Claude Sonnet handled comment filtering inside Claude Code. Karpathy’s only manual tasks were creating a Google Cloud API key, booting a VPS, and buying the domain.
The project illustrates how a developer can rely on Claude to automate data extraction and content curation, reducing traditional engineering effort to a few configuration steps.
