Why this result
o1-pro has the cleaner BenchAlign overall profile here, landing at 45 versus 43.32. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
o1-pro's sharpest advantage is in knowledge, where it averages 79 against 76.3. The single biggest benchmark swing on the page is GPQA, 72.2% to 79%.
o1-pro is also the more expensive model on tokens at $150.00 input / $600.00 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. Nemotron 3 Nano Omni 30B A3B gives you the larger context window at 256K, compared with 200K for o1-pro.
