o1-preview· Qwen3.6 Plus

Quick Verdict

Pick o1-preview if you want the stronger benchmark profile. Qwen3.6 Plus only becomes the better choice if instruction following is the priority or you need the larger 1M context window.

o1-preview has the cleaner overall profile here, landing at 72 versus 69. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

o1-preview's sharpest advantage is in reasoning, where it averages 85.4 against 62. The single biggest benchmark swing on the page is LongBench v2, 87% to 62%. Qwen3.6 Plus does hit back in instruction following, 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 200K for o1-preview.

Decision framing

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.
