Pick GLM-5 if you want the stronger benchmark profile. Qwen3.5-27B only becomes the better choice if coding is the priority or you need the larger 262K context window.
GLM-5 is clearly ahead on the aggregate, 75 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GLM-5's sharpest advantage is in reasoning, where it averages 77 against 60.6. The single biggest benchmark swing on the page is LiveCodeBench, 52% to 80.7%. Qwen3.5-27B does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Qwen3.5-27B is the reasoning model in the pair, while GLM-5 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. Qwen3.5-27B gives you the larger context window at 262K, compared with 200K for GLM-5.
BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.
Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
