+# FastAPI Llama2 Huggingface Hub API 
+
+This repository contains a Jupyter notebook (`FastAPI-Llama-HuggingfaceHub-Collab.ipyn`) that demonstrates how to set up and run a FastAPI server with Llama 2 model integration using Google Colab's free T4 GPU.
+
+## Features
+
+- Sets up a FastAPI server with Llama 2 model integration
+- Uses Google Colab's free GPU for model inference
+- Creates a public URL for the API using ngrok
+- Provides an example of how to make API requests to the server
+
+## Contents
+
+The notebook includes the following main sections:
+
+1. Installation of dependencies
+2. Setting up ngrok for creating a public URL
+3. Creating the FastAPI application
+4. Starting the FastAPI server
+5. Using ngrok to create a public URL for the server
+6. Testing the API with example requests
+
+## Usage
+
+1. Open the `FastAPI-Llama-HuggingfaceHub-Collab.ipynb` notebook in Google Colab
+2. Follow the instructions in the notebook to set up and run the server
+3. Use the provided ngrok URL to make API requests to the Llama 2 model
+
+## Requirements
+
+- Google Colab account (for free GPU access)
+- ngrok account (free tier is sufficient)
+
+## Note
