Ex-ChatGPT co-inventor launches Jev, a decision model claiming 20-200x speedup over LLMs
rohanpaul_ai · x · 2026-09-17
An author claiming to have co-invented ChatGPT and spent two years in stealth on a new training method (RLCD) announces Jev, a new model type optimized for making software decisions rather than generating text.
- Claimed 20-200x faster and 40-400x cheaper than LLMs (with free output tokens) by skipping token-by-token generation
- Instead of generating text that software must parse and validate, Jev takes data plus a predefined question and returns a typed choice or score with probabilities and confidence
- Described as a smart if-statement: a support app can ask if a ticket is urgent, policy-violating, and which queue it belongs to, then act directly
- All figures are vendor claims, unverified by third parties.
