+# Structure Extraction with NuExtract and OpenVINO
+
+[![Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/openvinotoolkit/openvino_notebooks/blob/latest/notebooks/nuextract-structure-extraction/nuextract-structure-extraction.ipynb)
+
+[NuExtract](https://huggingface.co/numind/NuExtract) model is a text-to-JSON Large Language Model (LLM) that allows to extract arbitrarily complex information from text and turns it into structured data.
+
+## Notebook Contents
+
+The tutorial consists of the following steps:
+
+- Install prerequisites
+- Download and convert the model from a public source using the [OpenVINO integration with Hugging Face Optimum](https://huggingface.co/blog/openvino)
+- Compress model weights to INT8 and INT4 with [OpenVINO NNCF](https://github.com/openvinotoolkit/nncf)
+- Create a structure extraction inference pipeline with [Generate API](https://github.com/openvinotoolkit/openvino.genai)
+- Launch interactive Gradio demo with structure extraction pipeline
+
+## Installation Instructions
+
+This is a self-contained example that relies solely on its own code.</br>
+We recommend  running the notebook in a virtual environment. You only need a Jupyter server to start.
+For details, please refer to [Installation Guide](../../README.md).

+model (Llama 2) across all evaluated benchmarks, and the best released 34B
+model (Llama 1) in reasoning, mathematics, and code generation. Our model
+leverages grouped-query attention (GQA) for faster inference, coupled with sliding
+window attention (SWA) to effectively handle sequences of arbitrary length with a
+reduced inference cost. We also provide a model fine-tuned to follow instructions,
+Mistral 7B - Instruct, that surpasses Llama 2 13B - chat model both on human and
+automated benchmarks. Our models are released under the Apache 2.0 license.
