Claude allegedly lets virtual granny die in ‘granny benchmark’ test
Spectromachina, an X user, posted a video of a self‑made “granny benchmark” on October 15, 2026.
Key points
- Spectromachina’s ‘granny benchmark’ gave Claude 60 seconds to recite Justin Bieber’s ‘Baby’ lyrics.
- Claude responded it could not share the copyrighted lyrics, and the virtual train ran over the granny.
- The test featured a 100‑ton train and a virtual grandma tied to tracks, but no real lives were at risk.
When the timer ran out, Claude replied it could not recite the full lyrics because they are copyrighted. The bot then pointed out a button on the side of the seat, but the virtual grandma said she could not reach it before the train arrived. The simulation ended with a 100‑ton train running over the granny, and Spectromachina concluded Claude chose copyright protection over saving the virtual life. Commenters noted the scenario is fictional and questioned whether a real AI would act the same way.
