ChatGPT co-inventor launches Jev, a decision-optimized frontier model claiming 193x speed, 445x cost savings
mazzaTalk · x · 2026-09-19
CompleteSkeptic, who claims to be a ChatGPT co-inventor, spent two years in stealth building a new training method (RLCD) and a new frontier model called Jev from TypeSafe AI, designed to skip chat and output structured decisions with confidence scores.
- Claimed 20-200x faster and 40-400x cheaper (free output tokens); a Chinese-language repost cites 193x faster and 445x cheaper on specific tasks
- Ships with an open-source plugin that compresses context to fight long-task memory loss
- Author calls it the shortest path to an AI-driven economic revolution
Setup: request access, have Codex install the TypeSafe Skill, create an API key, and append "Use the TypeSafe skill" to prompts. Claims are unverified by third parties.
