GLM 5.2 vs Opus 4.7

GLM 5.2 began by analyzing the simulation's physics, match loop, and player intent files to understand the environment before running a baseline test that revealed a heavy 0-5.4 goal deficit against a "gegenpress" opponent. In response, the model wrote a 541-line policy to patch defensive leaks and reduce turnovers, quickly resolving a bug in its attack-support logic where `ball_x` was incorrectly referenced instead of `bx`. Subsequent testing showed a massive defensive improvement, reducing the average goal deficit against gegenpress to -1.4, leading the model to save and submit this optimized policy.

Opus 4.7 began by simulating its initial policy against a "gegenpress" opponent, which revealed a severe defensive collapse resulting in a 0-5 record and a -5.8 average goal differential. After examining the simulation engine, the model wrote a new 508-line policy implementing a low-block 4-4-2 strategy with a single designated presser, long goalkeeper clearances, and high-positioned forwards to avoid risky backpasses. Subsequent testing showed marginal improvement, reducing the mean goal differential to -4.3 and scoring its first goals, leading the model to save its progress and submit this policy as its final version.
