Treat this as a split decision. DeepSeek V4 Pro (Max) makes more sense if coding is the priority or you want the cheaper token bill; GLM-5.2 is the better fit if agentic is the priority.
Confidence note. This is a partial-evidence comparison with 34 shared benchmark results across 7 evidence categories; 4 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
DeepSeek V4 Pro (Max) and GLM-5.2 finish on the same BenchAlign overall score, so this is less about a single winner and more about where the edge shows up. The BenchAlign headline says tie; the benchmark table is where the real choice happens.
GLM-5.2 is also the more expensive model on tokens at $1.40 input / $4.40 output per 1M tokens, versus $0.43 input / $0.87 output per 1M tokens for DeepSeek V4 Pro (Max). That is roughly 5.1x on output cost alone.
