Nemotron 4 340B Reward
Overview :
Nemotron-4-340B-Reward, developed by NVIDIA, is a multi-dimensional reward model used in synthetic data generation pipelines to assist researchers and developers in building their own LLMs. Composed of the Nemotron-4-340B-Base model and a linear layer, it converts response end-of-sequence markers into five scalar values corresponding to HelpSteer2 attributes. It supports a maximum context length of 4096 tokens and can score five attributes for each assistant turn.
Target Users :
Target audience: AI researchers and developers, especially those working on building and optimizing large language models (LLMs). This model can help them improve model performance and alignment through synthetic data generation and reinforcement learning techniques.
Use Cases
Researchers use the Nemotron-4-340B-Reward model to evaluate and improve the language models they build.
Developers utilize this model in conversational system development to generate training data, improving the system's response quality to user queries.
Educational institutions adopt this model as a teaching tool to help students understand the workings of large language models and optimization methods.
Features
Supports a maximum context length of 4096 tokens.
Scores five attributes of an assistant's response: helpfulness, correctness, coherence, complexity, and redundancy.
Can be used as a traditional reward model, outputting a single scalar value.
Commercially available under the NVIDIA Open Model License, allowing for the creation and distribution of derivative models.
Suitable for English synthetic data generation and English reinforcement learning based on AI feedback.
Can be used to align pre-trained models with human preferences or as a reward model for evaluation.
