Pick GPT-5.5 if you want the stronger benchmark profile. Nemotron 3 Nano Omni 30B A3B only becomes the better choice if mathematics is the priority or you want the cheaper token bill.
GPT-5.5 is clearly ahead on the provisional aggregate, 93 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.5's sharpest advantage is in coding, where it averages 58.6 against 53.5. The single biggest benchmark swing on the page is GPQA, 93.6% to 72.2%. Nemotron 3 Nano Omni 30B A3B does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
GPT-5.5 is also the more expensive model on tokens at $5.00 input / $30.00 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-5.5 gives you the larger context window at 1M, compared with 256K for Nemotron 3 Nano Omni 30B A3B.
GPT-5.5 is ahead on BenchLM's provisional leaderboard, 93 to 56. The biggest single separator in this matchup is GPQA, where the scores are 93.6% and 72.2%.
