Jev returns a decision in 227ms. The chat models take 2.5 to 3.5 seconds.

Four lanes, one game: same serve, same rules, same question, asked of a different model in each. One answer moves the ball one step, so every ball travels at its own model's answer time and nothing is skipped or sped up. Jev is a typed-decision model rather than a chat model, and Pong is the Atari game chat models handle worst, so a loop that won't wait is the fair place to see what that's worth.
