Nemotron 3 Ultra: Is NVIDIA a Model Company Now?
NVIDIA just released Nemotron 3 Ultra, a 550B mixture-of-experts model built on a hybrid Transformer-Mamba architecture, and it's a clear sign of how far NVIDIA has moved beyond being just a hardware company. In this video I break down what the model is actually good at and where it still lags, the other open-weight models NVIDIA is shipping across speech, retrieval, robotics, and world models, and the business logic behind giving it all away for free. I'll also walk through how to access Nemotron 3 Ultra via NVIDIA's API, including thinking, reasoning budgets, and tool calling. Thanks to @NVIDIADeveloper for early access.
