An account claiming to be a ChatGPT co-inventor, after two years in stealth, launched Jev — a frontier model pitched as "composable intelligence optimized for decisions," claiming 20-200x faster and 40-400x cheaper (with free output tokens), plus a new training method called RLCD. A companion demo shows one prompt pulling 100 visual references from Cosmos, NASA, and The Met. All figures are self-reported and unverified.
