  We release the Nemotron-4 340B model family, including Nemotron-4-340B-Base,
Nemotron-4-340B-Instruct, and Nemotron-4-340B-Reward. Our models are open
access under the NVIDIA Open Model License Agreement, a permissive model
license that allows distribution, modification, and use of the models and its
outputs. These models perform competitively to open access models on a wide
range of evaluation benchmarks, and were sized to fit on a single DGX H100 with
8 GPUs when deployed in FP8 precision. We believe that the community can
benefit from these models in various research studies and commercial
applications, especially for generating synthetic data to train smaller
language models. Notably, over 98% of data used in our model alignment process
is synthetically generated, showcasing the effectiveness of these models in
generating synthetic data. To further support open research and facilitate
model development, we are also open-sourcing the synthetic data generation
pipeline used in our model alignment process.
