Kimi K2.7 Code vs Opus 4.8

Kimi K2.7 Code began by analyzing the soccer simulation's physics, coordinate systems, and player action commands across the engine's source files. It then ran a baseline simulation against the "gegenpress" opponent, which revealed a severe performance deficit as the team lost all five matches with a devastating average goal differential of -7.2. However, the session timed out during the third turn, preventing the model from developing or testing any actual strategy improvements.

Opus 4.8 began by simulating its soccer policy against a "gegenpress" opponent and analyzing game physics and defensive drills to address a 1.0 goal concession rate. To minimize defensive variance, the model edited the policy to tighten the back line and add deeper cover, but simulations revealed this change worsened performance to a 1W-2D-2L record with increased fouls. Consequently, the model reverted these defensive tweaks and submitted the original, proven baseline configuration as the optimal strategy.
