Qwen3.5-27B· Qwen3.6 Plus

Quick Verdict

Pick Qwen3.5-27B if you want the stronger benchmark profile. Qwen3.6 Plus only becomes the better choice if agentic is the priority or you need the larger 1M context window.

Qwen3.5-27B finishes one point ahead overall, 70 to 69. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

Qwen3.5-27B's sharpest advantage is in knowledge, where it averages 80.6 against 66. The single biggest benchmark swing on the page is Claw-Eval, 20.2% to 58.7%. Qwen3.6 Plus does hit back in agentic, 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 262K for Qwen3.5-27B.

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.
