Post-ChatGPT researcher launches Jev, claiming 20-200x faster and 40-400x cheaper frontier model
ZhitingHu · x · 2026-09-19
- A researcher claiming to have co-invented ChatGPT announces Jev, a new type of frontier model built with a novel training method called RLCD, developed in stealth over two years.
- Claimed specs: 20-200x faster, 40-400x cheaper (output tokens free), framed as "frontier composable intelligence optimized for decisions" and "the shortest path to AI-based economic revolution."
- Researcher Zhiting Hu notes Jev echoes ALIGN, a text-alignment system her team built three years ago: next-token prediction is general but inefficient for many downstream tasks; a reusable discriminative function balances generalization and efficiency; pairing a large generator (LLM) with a small judge (ALIGN/Jev) improves overall system reliability.
- Claims come from the founder's own announcement, unverified by third parties.
