ChatGPT co-inventor launches Jev, a frontier model claiming 20-200x speed and 40-400x cost gains
JFPuget · x · 2026-09-19
An author claiming to have co-invented ChatGPT has spent two years in stealth building RLCD, a new training method, and Jev, a new frontier model focused on composable intelligence optimized for decisions.
- Claims 20-200x faster and 40-400x cheaper (with free output tokens)
- Positioned as a decision-optimized model rather than a chat model
- The author calls it 'the shortest path to AI-based economic revolution'
All numbers are self-reported and unverified.
