ChatGPT co-inventor launches Jev, a decision-focused AI model claiming 20-200x speed and 40-400x cost gains
HeyAmit_ · x · 2026-09-16
A self-described ChatGPT co-inventor, after two years in stealth, has released Jev, a new frontier AI model trained with a method called RLCD.
Key claims:
- Jev is optimized for decisions rather than text: it returns typed, structured decisions with probabilities and confidence scores that software can directly act on
- Claimed 20-200x faster and 40-400x cheaper (with free output tokens) versus existing models
- The software itself knows when to act and when to escalate to a human
The author frames it as the missing link between superhuman chat models and AGI, and the shortest path to an AI-driven economic revolution. The numbers are unverified marketing claims so far.
