GPT-4o mini· Qwen3.5-35B-A3B

Quick Verdict

Pick Qwen3.5-35B-A3B if you want the stronger benchmark profile. GPT-4o mini only becomes the better choice if agentic is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Qwen3.5-35B-A3B is clearly ahead on the aggregate, 68 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Qwen3.5-35B-A3B's sharpest advantage is in knowledge, where it averages 79.3 against 62. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 58% to 40.5%. GPT-4o mini does hit back in agentic, so the answer changes if that is the part of the workload you care about most.

GPT-4o mini is also the more expensive model on tokens at $0.15 input / $0.60 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 GPT-4o mini 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 128K for GPT-4o mini.

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.
