GLM-5.3 edges out GLM-5.2 in complex reasoning, but lags in code generation

A benchmark comparison reveals that GLM-5.3 outperforms GLM-5.2 on several complex reasoning tasks, including causal analysis and constraint satisfaction. However, both models struggled with an extreme mathematics problem, failing to produce a visible answer within token and time limits. GLM-5.2 demonstrated superior performance in generating executable optimization code, passing a hidden test suite, while GLM-5.3 required multiple retries and still failed to produce the optimal solution.
