Why this result
GPT-5.2 is clearly ahead on the BenchAlign aggregate, 57.62 to 43.32. 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 coding, where it averages 70.6 against 32. The single biggest benchmark swing on the page is GPQA, 92.4% to 72.2%.
GPT-5.2 is also the more expensive model on tokens at $1.75 input / $14.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Nano Omni 30B A3B. That is roughly Infinityx on output cost alone. GPT-5.2 gives you the larger context window at 400K, compared with 256K for Nemotron 3 Nano Omni 30B A3B.
