NVIDIA Nemotron vs. Llama 2

NVIDIA has developed the Nemotron series of open-source models designed to generate synthetic data for the training of large language models (LLMs) for commercial applications. Notably, the Nemotron-4 340B model is a significant breakthrough, offering developers a powerful tool to create high-quality data and enabling them to filter this data based on various attributes using a reward model. This innovation not only improves the data generation process but also optimizes the training of LLMs, catering to specific requirements and increasing efficiency. As a result, developers can more effectively harness the potential of synthetic data to enhance their language models.

We are excited to unveil the latest version of our open-source large language model, which includes model weights and initial code for the pretrained and fine-tuned Llama language models, ranging from 7 billion to 70 billion parameters. The Llama 2 pretrained models have been crafted using a remarkable 2 trillion tokens and boast double the context length compared to the first iteration, Llama 1. Additionally, the fine-tuned models have been refined through the insights gained from over 1 million human annotations. Llama 2 showcases outstanding performance compared to various other open-source language models across a wide array of external benchmarks, particularly excelling in reasoning, coding abilities, proficiency, and knowledge assessments. For its training, Llama 2 leveraged publicly available online data sources, while the fine-tuned variant, Llama-2-chat, integrates publicly accessible instruction datasets alongside the extensive human annotations mentioned earlier. Our project is backed by a robust coalition of global stakeholders who are passionate about our open approach to AI, including companies that have offered valuable early feedback and are eager to collaborate with us on Llama 2. The enthusiasm surrounding Llama 2 not only highlights its advancements but also marks a significant transformation in the collaborative development and application of AI technologies. This collective effort underscores the potential for innovation that can emerge when the community comes together to share resources and insights.
