Nvidia released an open 120-billion-parameter model that, after fine-tuning, outperformed Claude Opus 5 on one task.

According to Artificial Analysis, it is 5 times faster than its closest competitor in its class.

Without fine-tuning, the base model did not beat the closed flagships. For general everyday tasks, closed models like Opus 5.5 are more convenient because they work without any setup.

Open models have their own advantages: they can be fine-tuned on your own data and run on your own servers, and they are fast for large volumes of repetitive work.
