Jev, from a ChatGPT co-creator, makes AI decisions 200x faster and 400x cheaper
rubenhassid · x · 2026-09-21
Jev, a new viral app from one of the co-creators of ChatGPT, rethinks how AI answers questions by skipping text generation entirely.
- The problem: chatbots generate answers word by word, so even a yes/no question produces a paragraph the app must parse, risking hallucination.
- The approach: you describe a situation and ask a clear question with options (like a multiple-choice question); Jev returns a decision plus a confidence score.
- The numbers: the creator claims Jev is 200x faster and 400x cheaper than chatbots — so cheap you'd struggle to spend $5.
- The post includes copy-paste prompts. Jev is framed as a smart yes/no button making hundreds of decisions in parallel, not a better chatbot.
