These Jev game cases are the ones people screenshot: a playable fight scene, a first-person shooter, a browser game that runs without a game engine. What makes them a Jev use case rather than a chat-model trick is where the model sits — it does not write the game, it answers continuous typed questions (chase, wait, flank or retreat?) that the game loop executes in JavaScript.

Read them as evidence about latency and cost more than about graphics. A decision per entity per frame is only viable because a Jev call returns a label with a probability in milliseconds, and because output tokens are close to zero. Snippets below are the authors' own posts, kept with the original video.
