Nemotron 3 Super is the stronger all-rounder.gpt-oss-20b is better at agents.
Scores updated · 10 tests both models report · How we compare
Where each one wins
Tests won in each of the three areas where both have results. Each piece is one test, so a longer bar means more evidence; grey means the two scored within a point of each other.
Agents and reasoning rest on a single test each.
What it costs
Prices per million tokens, roughly 750,000 words. The bars show the cost of a million tokens read plus a million written.
The biggest differences
The tests each model wins by the widest margin, up to three each. Scores are out of 100.

Questions people ask
Which is better, gpt-oss-20b or Nemotron 3 Super?
Nemotron 3 Super wins two of the three areas where both have results: coding and reasoning. gpt-oss-20b wins agents.
Which is better for coding?
Nemotron 3 Super. It wins 3 of the 4 coding tests both models report; gpt-oss-20b wins 1.
How do you compare the two?
We use the 10 benchmark tests both models have published scores on. The verdict counts the 6 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 4 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
