Stop using your most expensive model for every decision. In our Minesweeper experiment (open-source code below), JEV crushed every other model we tested on speed and cost. JEV: 8s / ~$0.003 Fable 5.1: 100s / ~$2.41 Astra: 128s / ~$8.75 Grok 4.6: 158s / ~$0.55 Where would you put JEV to work in your company?
