Why this result
Inkling is clearly ahead on the provisional aggregate, 69 to 61. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Inkling's sharpest advantage is in agentic, where it averages 69.4 against 51.3. The single biggest benchmark swing on the page is BrowseComp, 77.1% to 44.4%. Nemotron 3 Ultra does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
Inkling is also the more expensive model on tokens at $1.87 input / $4.68 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 is the reasoning model in the pair, while Inkling is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use.
