My 10 year old son Troy has made a card game. It has 27 characters, each with different powers. You can download it here https://www.dropbox.com/s/jrgphx4vn95va4z/LegimonChristmasSet2013.pdf His goal is to have 100 kids play it, and he wants to give it away free as a Christmas present so that more kids can play it.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
