Baby Rap Lab

Your laptop writes a rap for little ones, sings it in a human-sounding voice and drops it on a beat. Every bit of AI here runs on this computer.

What just happened?

Writing: a small language model predicts the next token (a word or piece of a word) over and over. Purple flashes are new tokens.

Singing: Kokoro, an 82-million-parameter text-to-speech model, turns each line into a voice.

Beat: no AI here, just code: a drum and a xylophone made from maths, with each line dropped onto a bar.
