ChatGPT co-inventor launches Jev model claiming 20-200x speed and 40-400x cost cuts

A ChatGPT co-inventor unveiled Jev, a new frontier model trained with a novel method called RLCD after two years in stealth, claiming 20-200x faster inference, 40-400x lower cost with free output tokens, and 'frontier composable intelligence' optimized for decisions.
The post frames it with a neuroscience analogy: brains need a fast, dumb System 1 to free the slower, smarter System 2 for what matters. Likewise, a model smart enough to control a robotic hand can't also do frontier math if its context window is polluted with vision/control tokens — pairing a powerful model with a faster, still-intelligent one is the way forward.
