Winner · 6/8 categoriesGemini 3.1 Flash-Lite· Qwen3.5-27B
Pick Qwen3.5-27B if you want the stronger benchmark profile. Gemini 3.1 Flash-Lite only becomes the better choice if reasoning is the priority or you need the larger 1M context window.
Qwen3.5-27B is clearly ahead on the aggregate, 70 to 54. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Qwen3.5-27B's sharpest advantage is in coding, where it averages 77.6 against 24.3. The single biggest benchmark swing on the page is LiveCodeBench, 21% to 80.7%. Gemini 3.1 Flash-Lite does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.
Gemini 3.1 Flash-Lite is also the more expensive model on tokens at $0.10 input / $0.40 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-27B. That is roughly Infinityx on output cost alone. Qwen3.5-27B is the reasoning model in the pair, while Gemini 3.1 Flash-Lite 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. Gemini 3.1 Flash-Lite gives you the larger context window at 1M, compared with 262K for Qwen3.5-27B.
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.
