Nemotron-4 15B vs o1

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

Nemotron-4 15B finishes one point ahead overall, 52 to 51. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

o1 is the reasoning model in the pair, while Nemotron-4 15B 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. o1 gives you the larger context window at 200K, compared with 32K for Nemotron-4 15B.

Quick Verdict

Pick Nemotron-4 15B if you want the stronger benchmark profile. o1 only becomes the better choice if knowledge is the priority or you need the larger 200K context window.
