Why this result

GLM-5.1 has the cleaner BenchAlign overall profile here, landing at 67.74 versus 65.2. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

GLM-5.1's sharpest advantage is in agentic, where it averages 65.4 against 61.6. The single biggest benchmark swing on the page is HLE, 52.3% to 28.8%. Qwen3.6 Plus does hit back in coding, so the answer changes if that is the part of the workload you care about most.

Qwen3.6 Plus gives you the larger context window at 1M, compared with 203K for GLM-5.1.
