ChatGPT co-inventor launches Jev: 20-200x faster, 40-400x cheaper decision model
hardimanjames · x · 2026-09-16
@CompleteSkeptic, a self-described co-inventor of ChatGPT, launched Jev after two years in stealth: a frontier model trained with a new method (RLCD) claiming 20-200x speedups, 40-400x lower cost (free output tokens), and "composable intelligence" optimized for decisions. Commenters read it as an abstraction shift — modeling decision spaces as typed probabilistic outputs with composable uncertainty, neural nets handling semantics while deterministic code handles thresholds, flow and policy, like a "probabilistic if statement."
