Model Overview

---

Description:

The NVIDIA Gemma-2b-it INT4 ONNX model is the quantized version of the Google Gemma-2b-it model which is a text-to-text, decoder-only large language models, available in English, with open weights, pre-trained variants, and instruction-tuned variants. It is well-suited for a variety of text generation tasks, including question answering, summarization, and reasoning. Relatively small size makes it possible to deploy them in environments with limited resources such as a laptop, desktop or your own cloud infrastructure. For more information, please check here. The NVIDIA Gemma-2b-it INT4 ONNX model is quantized with TensorRT Model Optimizer.

This model is ready for commercial and research use case.

Steps followed to generate this quantized model:

• Download Google Gemma-2b-it model in Pytorch bfloat16 format from HuggingFace.

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

• Quantize Gemma-2b-it ONNX FP16 model to Gemma-2b-it ONNX INT4 AWQ model using TensorRT Model Optimizer – Windows.
