3/8 categoriesClaude Sonnet 4.5· Qwen3.5-35B-A3B
Pick Claude Sonnet 4.5 if you want the stronger benchmark profile. Qwen3.5-35B-A3B only becomes the better choice if coding is the priority or you want the cheaper token bill.
Claude Sonnet 4.5 has the cleaner overall profile here, landing at 69 versus 67. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Claude Sonnet 4.5's sharpest advantage is in multimodal & grounded, where it averages 91.4 against 75.1. The single biggest benchmark swing on the page is SuperGPQA, 91% to 63.4%. Qwen3.5-35B-A3B does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Claude Sonnet 4.5 is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-35B-A3B. That is roughly Infinityx on output cost alone. Qwen3.5-35B-A3B is the reasoning model in the pair, while Claude Sonnet 4.5 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. Qwen3.5-35B-A3B gives you the larger context window at 262K, compared with 200K for Claude Sonnet 4.5.
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.
