Self-described ChatGPT co-inventor launches Jev, claiming 20-200x speed at 40-400x lower cost

CompleteSkeptic, describing himself as a ChatGPT co-inventor, launched Jev after two years in stealth: a new frontier model trained with a new method called RLCD, claiming 20-200x faster, 40-400x cheaper (output tokens free), and "frontier composable intelligence optimized for decisions" — billed as the shortest path to an AI-based economic revolution.

lateinteraction's take: Jev is what you'd design if you took DSPy's Predict(Signature) abstraction seriously enough to build a foundation model for executing it. Unverified claims; no architecture details or benchmarks public yet.
