This is now v2 with minified JS! This version features a minimal GPT implementation with native browser execution through data URI with <40 lines of minified JS and no external dependencies
It makes use of the DecompressionStream Web API and a similiar logic to my past project of running a DOOM-like game from a QR code
you can quite literally "train" and run inference of a GPT model from your mobile device
Would love to hear what you think about it !
