Here are the results from the Pac-Man bench. It does pretty well for the price, around Sonnet 5.5.
Kimi K3.1 Pro ties Sonnet 5.5 at 93, for $0.68 and 11 min vs Sonnet's $1.61 and 14 min.

On mobile Kimi definitely wins from the UX point of view
Until I looked, I thought I'd see Kimi vs Claude competitive gaming with pacman.
That would have been interesting to watch, which model gets the highest score.
Interestingly, the Kimi one seems to implement the safe spot bug from the arcade original [1], while the Claude one doesn’t.
The prompt says that the agent shouldn’t look up existing implementations on the internet, so I’m guessing that the implementation is baked in?
