ChatGPT co-inventor launches Jev, claiming 20-200x speed and 40-400x cost gains

After two years in stealth, @CompleteSkeptic — who describes himself as a ChatGPT co-inventor — launched Jev, a new frontier model from TypeSafe AI built with a claimed new training method called RLCD.
Key claims:
- 20-200x faster and 40-400x cheaper than existing options, with output tokens free
- "Frontier composable intelligence" optimized for decisions, pitched as the shortest path to an AI-driven economic revolution
- Framed around the question of why superhuman chat models haven't produced AGI
A demo use case called Toothless shows Jev running as an always-on voice AI that can tell in real time whether you're talking to it or to someone else nearby — addressing the unnatural wake-word flow of Siri/Alexa and ChatGPT voice's 1:1-only limitation.
Note: performance figures are unverified vendor claims.
