Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Nemotron 3 Super 120B A12B finishes one point ahead overall, 61 to 60. 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.
Nemotron 3 Super 120B A12B's sharpest advantage is in coding, where it averages 44.2 against 38.9. The single biggest benchmark swing on the page is HumanEval, 59 to 69. Kimi K2.5 does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.
Kimi K2.5 is also the more expensive model on tokens at $0.50 input / $2.80 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Super 120B A12B. That is roughly Infinityx on output cost alone. Nemotron 3 Super 120B A12B gives you the larger context window at 256K, compared with 128K for Kimi K2.5.
Pick Nemotron 3 Super 120B A12B if you want the stronger benchmark profile. Kimi K2.5 only becomes the better choice if multimodal & grounded is the priority.
