Questions

Is Nemotron 3 Ultra better than o1 for coding?

Only Nemotron 3 Ultra has a coding score, 30.0 on the Vibe Coding Index; o1 has none, so the two cannot be ranked on coding. Pick o1 for work measured by WeirdML or TaxEval (Vals AI), where it leads.

Which is cheaper, Nemotron 3 Ultra or o1?

Nemotron 3 Ultra costs $0.60 per million input tokens and $2.40 per million output tokens; o1 costs $15.00 and $60.00. Cost per solved task is known for neither of them.

Which has the bigger context window, Nemotron 3 Ultra or o1?

Nemotron 3 Ultra, with 262K tokens against 200K.

How many benchmarks is the Nemotron 3 Ultra vs o1 comparison based on?

45 benchmarks have a result for both models as of October 22, 2026. Nemotron 3 Ultra's coding index rests on 3 independent benchmarks and o1's on 0. Where only one model has a result, the page says so instead of naming a winner.
