ChatGPT co-inventor launches Jev, a decision-optimized model claiming 20-200x speed and 40-400x cost gains

The co-inventor of ChatGPT announced Jev, a new frontier model built over 2 years in stealth using a training method called RLCD, positioned as composable intelligence optimized for decisions: 20-200x faster and 40-400x cheaper than general chat models, with output tokens free. Instead of plain text it returns answers as code, making it easy for developers to classify inputs — e.g., triage support tickets by team, user frustration, and urgency. The author claims it is the shortest path to AI-based economic revolution.
