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.

The four lanes are deliberately the four everyone knows. Since recording them the same question has been put to five more models, including GPT-6 Astra and Claude Fable 5.1. Same result. See the numbers.
