# NewsGPT Using LangChain and FastAPI     This repository contains an implementation of NewsGPT, a news summarization model, using **LangChain** and **FastAPI**. This model is production-ready and can seamlessly function as a standalone application or be seamlessly integrated into other applications. Through this project, you have the capability to produce concise summaries of news articles, providing you with the primary highlights of each article. ## Table of Contents - [1.

License](#license) - [7. Contributions](#contributions) ## 1. Introduction NewsGPT is a powerful language model that can generate coherent and contextually relevant summaries of news articles. This project leverages LangChain, a state-of-the-art language model, and FastAPI, a modern web framework, to create an API for generating news articles on-the-fly. It employs [BART Large CNN](https://huggingface.co/facebook/bart-large-cnn) model as LLM. Additionally, it extends support for seamless integration with **OpenAI's ChatGPT**. ## 2. Installation Before you begin, ensure you have Python 3.9+ installed on your system. You can then set up the project as follows: #### 2.1 Clone the repository: ```bash git clone https://github.com/MUmairAB/NewsGPT-Using-LangChain-and-FastAPI.git cd NewsGPT-Using-LangChain-and-FastAPI ``` #### 2.2 Install the required dependencies: ``` pip install -r requirements.txt ``` #### 2.3 Replace your own HuggingFace **Access Key** in **secret_key.py** file. ## 3. Usage To use NewsGPT, follow these steps: #### 3.1 Step 1: If you are running the code in Google Colab, then proceed to the next step. But if you are running the code on your local computer, then make the following changes in **NewsGPT Code** file. **A)** Remove the following code from the file. ``` #The following code is necessary to run the FastAPI app in Colab # But if you are running it locally, then you can un-comment the following app.add_middleware( CORSMiddleware, allow_origins=['*'], allow_credentials=True, allow_methods=['*'], allow_headers=['*'], ) ``` **B)** Replace the following code: ``` #Run the FastAPI app on local server import nest_asyncio from pyngrok import ngrok import uvicorn ngrok_tunnel = ngrok.connect(8000) print('Public URL:', ngrok_tunnel.public_url) nest_asyncio.apply() uvicorn.run(app, port=8000) ``` with ``` import uvicorn uviconr.run(app="NewsGPT Code:app", host="127.0.0.1", port=8000, reload=True) ``` #### 3.2 Step 2 **A)** Start the FastAPI web server: ``` python 'NewsGPT Code.py' ``` **B)** Open your web browser and navigate to http://localhost:8000/docs to access the Swagger documentation and try out the API endpoints. **C)** Use the API endpoints to generate news article summaries programmatically. ## 4. API Endpoints #### 4.1 /summary: Generate summarised news articles by providing the article's URL as input prompts. For detailed information on how to use each endpoint, refer to the Swagger documentation available at **http://localhost:8000/docs**. ## 5. Screenshots of the Working App Following are the snaps of the running app. #### 5.1 Using the NewsGPT app in a web browser. #### 5.2 Using the NewsGPT app from the GitBash terminal using the [Bash Script](https://github.com/MUmairAB/NewsGPT-Using-LangChain-and-FastAPI/blob/main/bash_code.sh) #### 5.3 Using the NewsGPT app from local IDE using [Python Script](https://github.com/MUmairAB/NewsGPT-Using-LangChain-and-FastAPI/blob/main/Use%20NewsGPT%20from%20IDE.py). ## 6. License This project is licensed under the MIT License. Feel free to use, modify, and distribute this code for your own purposes. ## 7.
