GLM-5.3 costs $1.40 per million input tokens and $4.40 per million output tokens; Nemotron 3 Ultra 550B A55B costs $0.60 and $2.70. That makes Nemotron 3 Ultra 550B A55B about 43% cheaper for the same work.
How do you compare the two?
We use the 31 benchmark tests both models have published scores on. The verdict counts the 18 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 13 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.
