Pick Nemotron 3 Ultra if you want the stronger benchmark profile. GPT-5.4 nano only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
Confidence note. This is a partial-evidence comparison with 20 shared benchmark results across 5 evidence categories; 2 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
Nemotron 3 Ultra has the cleaner provisional overall profile here, landing at 63 versus 60. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Nemotron 3 Ultra's sharpest advantage is in knowledge, where it averages 54.2 against 43.8. The single biggest benchmark swing on the page is HLE, 37.7% to 26.7%.
GPT-5.4 nano is also the more expensive model on tokens at $0.20 input / $1.25 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Ultra. That is roughly Infinityx on output cost alone. Nemotron 3 Ultra gives you the larger context window at 1M, compared with 400K for GPT-5.4 nano.
