NVIDIA Research released the Nemotron-4 340B model family with models designed to perform competitively on a range of evaluation benchmarks. Models include Nemotron-4-340B-Base, Nemotron-4-340B-Instruct, and Nemotron-4-340B-Reward, and are open access under the NVIDIA Open Model License Agreement. These models can be deployed on a single DGX H100 with 8 GPUs in FP8 precision and are particularly effective for generating synthetic data.
