Jev, the first decision-only AI model, makes calls in 200ms for a fraction of a cent
Cole Medin · youtube · 2026-09-21
Cole Medin demos Jev, a new class of AI model that generates no text at all—it takes a state and a list of typed questions and returns probabilistic decisions in 200ms at negligible cost. Use cases he tested include playing his indie game at three decisions per second, triaging every open PR in his repo, and routing each agent request to the right model. His core claim: any gate in your AI coding setup that used to be a regex or a slow LLM call is now a candidate for Jev. Community demos include Jev playing Doom, browser automation via browser-use/jev-ultrafast, Jev vs. LLMs at Pong, and the Awesome Jev collection.
