Stealth startup launches Jev, claiming 20-200x faster and 40-400x cheaper than frontier models with free output tokens

An account claiming to be a ChatGPT co-inventor has emerged from two years of stealth to launch RLCD, a new training method, and Jev, a frontier model described as composable intelligence optimized for decisions.

The quote-tweeter argues going all-in on structured output is the killer use case: cheap model intelligence filling schemas and driving backend logic, with Jev's free output economics potentially taking over smart automation. All claims are unverified vendor marketing — treat with skepticism until independent benchmarks appear.
