Pick GLM-4.6 if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if mathematics is the priority or you need the larger 1M context window.
Confidence note. This is a partial-evidence comparison with 13 shared benchmark results across 6 evidence categories; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
GLM-4.6 is clearly ahead on the BenchAlign aggregate, 55.12 to 51.11. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GLM-4.6 is the reasoning model in the pair, while GPT-4.1 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-4.1 gives you the larger context window at 1M, compared with 200K for GLM-4.6.
