Composer 2 vs Nemotron-4 15B

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

Composer 2 is clearly ahead on the aggregate, 62 to 46. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Composer 2's sharpest advantage is in agentic, where it averages 61.7 against 41.3. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 61.7% to 37%.

Composer 2 is also the more expensive model on tokens at $0.50 input / $2.50 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron-4 15B. That is roughly Infinityx on output cost alone. Composer 2 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. Composer 2 gives you the larger context window at 200K, compared with 32K for Nemotron-4 15B.

Quick Verdict

Pick Composer 2 if you want the stronger benchmark profile. Nemotron-4 15B only becomes the better choice if you want the cheaper token bill or you would rather avoid the extra latency and token burn of a reasoning model.
