Claude 4 Sonnet vs Nemotron 3 Nano Omni 30B A3B

Pick Nemotron 3 Nano Omni 30B A3B if you want the stronger benchmark profile. Claude 4 Sonnet only becomes the better choice if coding is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Nemotron 3 Nano Omni 30B A3B is clearly ahead on the provisional aggregate, 56 to 51. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Claude 4 Sonnet is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Nano Omni 30B A3B. That is roughly Infinityx on output cost alone. Nemotron 3 Nano Omni 30B A3B is the reasoning model in the pair, while Claude 4 Sonnet 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. Nemotron 3 Nano Omni 30B A3B gives you the larger context window at 256K, compared with 200K for Claude 4 Sonnet.
