[TESTE] Karpathy Launches HackerTube, a Claude-Curated Video List Built From Hacker News
Andrej Karpathy used Claude to filter 43 million Hacker News comments down to 6,454 videos the community keeps recommending.
A weekend project swaps YouTube’s algorithm for 20 years of Hacker News community recommendations.
Andrej Karpathy unveiled HackerTube on Sunday, November 1, 2026, calling it a “weekend hack” born of his annoyance with YouTube’s recommendations. He had Claude filter 43 million comments posted over 20 years on Hacker News down to 6,454 videos that keep getting recommended.
About Two Hours With Opus 5.5
Karpathy says the project took roughly two hours with Opus 5.5 and delivers a “significantly” better viewing experience.
Shawn Wang (@swyx) added that Karpathy used the “medium” effort level on Opus 5.5 for the project, likening debates over effort levels to the tabs-vs-spaces argument.
