Which is better for coding?
NVIDIA Nemotron 3 Nano 30B A3B. It wins 3 of the 4 coding tests both models report; GPT-4o wins 1.
Which is cheaper?
GPT-4o costs $5.00 per million input tokens and $15.00 per million output tokens; NVIDIA Nemotron 3 Nano 30B A3B costs $0.05 and $0.20. That makes NVIDIA Nemotron 3 Nano 30B A3B about 99% cheaper for the same work.
How do you compare the two?
We use the 29 benchmark tests both models have published scores on. The verdict counts the 14 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 15 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.
