Every death forks the VM into four timelines and tries again.
appcypher built Mario Never Dies on Jev and microsandbox. Jev picks every move, and each time Mario dies the whole virtual machine forks into four timelines that try again. Whichever Mario survives becomes the canonical run.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x
