Summary

The video is a live stream from NVIDIA Developer, hosted by Chris Alex and Chintan Patel, providing an in-depth overview of the NVIDIA Llama Nemotron family of open reasoning models. They discuss the motivation behind the models, focusing on high accuracy for agentic AI and efficiency. The training process involves starting with open frontier models, pruning, knowledge distillation, and applying techniques like supervised fine-tuning and reinforcement learning. They highlight two models: Llama Nemotron Super 1.5 (49B) and Nano 2 (9B). Super 1.5 achieves state-of-the-art performance on a single H100, while Nano 2 introduces a hybrid transformer-Mamba architecture for edge deployment and a ’thinking budget’ feature to control reasoning compute. The presentation includes benchmark comparisons, efficiency gains, and a live demo showing how to use the models via Hugging Face and NVIDIA’s build endpoint. They emphasize openness, releasing models, training data, and techniques. The session concludes with community Q&A.
