Self-proclaimed ChatGPT co-inventor launches 'Jev' model claiming 400x cost cut
hardimanjames · x · 2026-09-18
An account claiming to have "co-invented ChatGPT" and spent 2 years in stealth on a new training method (RLCD) announced a supposed frontier model called Jev, claiming:
- 20-200x faster than existing models
- 40-400x cheaper (output tokens free)
- Frontier "composable intelligence" optimized for decisions
The claims are highly dubious: the identity is unverified, and the name Jev appears to nod to Jevons Paradox, fueling suspicion it is a hoax or performance art. Boosters praise the launch timing as impeccable. Treat as an unverified, likely trolling announcement.
