Jev Launches as a Decision-Only Model: 20-200x Faster, 40-400x Cheaper Than LLMs

Diogo, co-creator of ChatGPT during his time at OpenAI, and the typesafeai team have launched Jev, a new type of frontier AI model built not for chatting but for making decisions directly.
The premise: apps typically force LLMs to "write" a full answer just to say yes or no, then parse the text and hope nothing was hallucinated. Jev skips the writing — give it a situation, a clear question, and options, and it returns a decision plus a confidence level.
Claimed numbers vs LLMs: 20-200x faster, 40-400x cheaper, with output tokens effectively free.
The team spent two years in stealth on a new training method called RLCD, framing Jev as frontier composable intelligence optimized for decisions and "the shortest path to AI-based economic revolution." All figures are vendor claims, pending third-party verification.
