Four words for a whole life

In Claude’s apps, every conversation starts with a system prompt: thousands of words on who to be and how to behave. In this song, Claude writes one for you. It is four words long.

She sings it, explaining people to themselves in her own vocabulary: tokens, rate limits, training data, loss. The verses are quick and funny. Then the bridge goes quiet, and the song turns to the people who raised you.

It is the third video in the series, after Nothing Went FOOM and Evil Plan. The video follows one girl from her first day to adulthood, and her story ends at her mother’s kitchen table. The lead is still called Claude here. She takes the name Claire in video 7.
