ChatGPT co-inventor unveils Jev, a prediction-only model claiming 20-200x speed, 40-400x cheaper
danshipper · x · 2026-09-16
@CompleteSkeptic, claiming to be a ChatGPT co-inventor, emerged from two years of stealth to release RLCD (a new training method) and Jev, a frontier model that generates no text and only makes predictions — a 'thinking engine, not a text engine.'
Key claims:
- 20-200x faster and 40-400x cheaper than LLMs, with free output tokens
- Positioned as frontier composable intelligence optimized for decisions, not chat
- The author argues 'arbitrary prediction' is closer to real brains than LLMs and the shortest path to an AI-driven economic revolution
Boosters point to a DOOM demo buried in the thread. Note: claims are self-reported and unverified.
