Model Overview

---

Description:

Nemotron-Mini-4B Instruct is a model for generating responses for roleplaying, retrieval augmented generation, and function calling. It is a small language model (SLM) optimized through distillation, pruning and quantization for speed and on-device deployment. VRAM usage has been minimized to approximately 2 GB, providing significantly faster time to first token compared to LLMs. The NVIDIA Nemotron-Mini-4B Instruct ONNX INT4 model is quantized with TensorRT Model Optimizer.

Steps followed to generate this quantized model:

• Download Nemotron-Mini-4B Instruct model in Pytorch bfloat16 format from HuggingFace.

• Convert PyTorch model to ONNX FP16 using onnxruntime-genai model builder.

• Quantize Nemotron-Mini-4B Instruct ONNX FP16 model to Nemotron-Mini-4B Instruct ONNX INT4 AWQ model using TensorRT Model Optimizer – Windows.

This model is ready for commercial/non-commercial use.
