ChatGPT Co-Inventor Launches Jev, a Frontier Model Claiming 20-200x Speed and 40-400x Cost Cuts
revodavid · x · 2026-09-17
CompleteSkeptic, who describes himself as a co-inventor of ChatGPT, has come out of two years of stealth to launch Jev, a new frontier model trained with a novel method called RLCD and positioned as "frontier composable intelligence optimized for decisions."
- Claims 20-200x faster inference and 40-400x cheaper operation, with output tokens free
- The author argues that superhuman chat models haven't led to AGI, and frames Jev as the shortest path to an AI-driven economic revolution
- A 45-second TL;DR video accompanies the launch, though even the sharer found it hard to follow
All performance figures are self-reported and unverified by third parties.
