DavidKPiano's Jevspresso: XState constrains, Jev decides in a coffee-machine AI demo

DavidKPiano · x · 2026-10-03

DavidKhourshid (XState creator) released "Jevspresso", a playful demo combining state machines with an AI model: XState defines what transitions are possible, while Jev decides the next move. You can order in plain language—or deliberately break things and watch how the model copes with invalid states. A hands-on showcase of constraining LLM actions with formal state machines.
