Nemotron 4 340B Instruct
Overview :
Nemotron-4-340B-Instruct is a large language model (LLM) developed by NVIDIA, specifically optimized for English single-turn and multi-turn dialogue scenarios. This model supports a context length of 4096 tokens and has undergone additional alignment steps such as supervised fine-tuning (SFT), direct preference optimization (DPO), and reward-aligned preference optimization (RPO). Based on approximately 20K manually annotated data points, the model leveraged a data synthesis pipeline to generate over 98% of the data used for supervised fine-tuning and preference fine-tuning. This enables the model to exhibit strong performance in human-like conversational preferences, mathematical reasoning, coding, and instruction following, and it can also generate high-quality synthetic data for various use cases.
Target Users :
The Nemotron-4-340B-Instruct model is designed for developers and businesses looking to build or customize large language models. It is particularly suitable for users who need to apply AI technology in areas such as English conversation, mathematical reasoning, and programming assistance.

Features
Supports a context length of 4096 tokens, suitable for processing long texts.
Optimized for dialogue and instruction following capabilities through SFT, DPO, and RPO alignment steps.
Can generate high-quality synthetic data, assisting developers in building their own LLMs.
Utilizes Grouped-Query Attention (GQA) and Rotary Position Embeddings (RoPE) techniques.
Supports customizable tools within the NeMo Framework, including parameter-efficient fine-tuning and model alignment.
Demonstrates strong performance on various benchmark datasets, such as MT-Bench, IFEval, and MMLU.
How to Use
1. Create a Python script using the NeMo Framework to interact with the deployed model.
2. Create a Bash script to initiate the inference server.
3. Utilize the Slurm job scheduling system to distribute the model across multiple nodes and associate it with the inference server.
4. Define a text generation function within the Python script, specifying the request headers and data structure.
5. Call the text generation function, providing the prompt and generation parameters to retrieve the model's response.
6. Adjust generation parameters such as temperature, top_k, and top_p as needed to control the style and diversity of text generation.
7. Refine the system prompt to optimize the model's output and achieve better conversational outcomes.
