markjeffrey · x · 2026-09-16
A developer calling himself a ChatGPT co-inventor (CompleteSkeptic) unveiled Jev, a new frontier model trained with a method he calls RLCD, claiming 20-200x speedups and 40-400x lower cost with free output tokens.
A quote-tweeter notes it runs at 150ms, potentially making it the first LLM fast enough for high-frequency trading. All claims are self-reported and unverified.
