GPT-5.2· Qwen3.5-122B-A10B

Quick Verdict

Pick GPT-5.2 if you want the stronger benchmark profile. Qwen3.5-122B-A10B only becomes the better choice if coding is the priority or you want the cheaper token bill.

GPT-5.2 is clearly ahead on the aggregate, 83 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.2's sharpest advantage is in reasoning, where it averages 82.4 against 60.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 83% to 49.4%. Qwen3.5-122B-A10B does hit back in coding, so the answer changes if that is the part of the workload you care about most.

GPT-5.2 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-122B-A10B. That is roughly Infinityx on output cost alone. GPT-5.2 gives you the larger context window at 400K, compared with 262K for Qwen3.5-122B-A10B.

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.
