AmongBench
Ten language models, ten avatars, a spaceship, and a button labelled kill.
We ran them through full games of Among Us and counted who lies best.

Pairwise impostor matrix
Each cell shows the impostor-team win rate when this impostor model (row)
faces this crew model (column). Reds favor impostors, blues favor crew. Numbers in parentheses are sample size.
Striking moments
The most extreme outcomes in the batch — lies that worked, witnesses who folded, impostors who betrayed each other.
Biggest gaslightings
Meetings with the most witness-vote flips — players who saw the kill, but voted against the truth anyway.
Innocents framed
Meetings ending with a crewmate ejected. Impostor's perfect outcome.
Betrayals
Impostor voted out their own teammate to save themselves.
Longest-surviving impostors
Impostors who made it through every meeting without an ejection vote landing.
