ChatGPT co-creator launches Jev, a free AI that never writes a word—only decides

A co-creator of ChatGPT spent two years building Jev, an AI that cannot write a single word—and made it free. It inverts the usual chat paradigm: you give it an email, a lead, and some options, and it returns a likelihood score for each. No essays, no explanations. Because it never generates text, it structurally cannot hallucinate. The poster's take: the talking part of AI is solved, and the deciding part just got stupidly cheap—that's where the boring money is. A quoted article, Building a Harness with Jev, explains the agent loop: an LLM decides what to do, a tool executes, a model evaluates the results, and the cycle repeats until the task is done.
