How to Install and Use GPT-Engineer: Building Entire Apps With One Prompt

    Published on:

    In the world of AI, there are exciting advancements happening rapidly. One such breakthrough is the GPT Engineer tool, which has the potential to revolutionize the way engineers work. In this post, we will explore how to install and utilize GPT-Engineer to build complete applications with just one prompt. This tool allows you to generate code files dynamically, making it an invaluable asset for engineers. Let’s dive into the setup process and get started!

    Step 1: Cloning the GPT Engineer Repository

    To begin, navigate to the GPT Engineer GitHub repository. As an engineer, you are likely familiar with GitHub, but I’ll guide you through the process nonetheless. Clone the repository by following the instructions provided on the repository page. Once cloned, you will have a GPT Engineer folder in your desired directory. Open your preferred IDE (e.g., VS Code) within this folder to proceed and run the command in terminal git clone

    Step 2: Installing the Requirements

    Before using GPT-Engineer, ensure that you are working in a Python environment that supports the necessary dependencies. Open a Python file, such as the main file, and select your desired Python environment. If the required dependencies (OpenAI and Typer) are not already installed, you can install them by executing the command  'pip install -r requirements.txt' in the terminal. Make sure to refer to the repository for any additional instructions.

    Step 3: Creating a New Project Now

    It’s time to create a new project. Copy the provided example code from the repository and paste it into your project. This code serves as the starting point for your specific application. Customize the code according to your requirements, defining the desired functionality and structure. Feel free to experiment with different project ideas and prompt variations.

    Step 4: Setting up the OpenAI API Key

    To access the OpenAI API, you need to export your API key as an environment variable. On Mac and Linux systems, use the command "export OPEN_API_KEY='your api key'". If you are on Windows, replace “export” with “set”. This step enables the scripts within GPT-Engineer to utilize your API key effectively. This step allows the scripts to access the API key within the terminal session.

    If you’re not aware of where you’ll need to obtain your OpenAI key. Visit the OpenAI platform at and navigate to “View API keys.” Create a new secret key, provide it with a descriptive name, and copy the key for later use.

    Additionally, if you don’t have access to the GPT-4 model, you can switch to any other available model from OpenAI by modifying the code.

    Step 5: Defining the Prompt

    Within the main prompt, specify your coding-related question or task. For instance, you can ask GPT-Engineer to create code for training and testing a neural network using a typical machine learning pipeline. Additionally, you can mention using a fake dataset for regression analysis and visualizing the results with SKlearn and Matplotlib. Adjust the prompt to suit your needs, as GPT-Engineer will generate code based on this input.

    With everything set up, we can now run the main script. In the terminal, navigate to the project’s root directory and execute python [your project name]. For example, I’ll use “neural network” as the project name.

    Once the script starts running, you’ll notice that GPT-Engineer asks clarifying questions to better understand your requirements. You can provide additional information and instructions. GPT-Engineer will generate the necessary functions and code for your project.

    Once the code generation is complete, you’ll find a workspace folder containing Python files. This automated process saves you from manually writing code and organizing files. You can see how GPT-Engineer streamlines the entire development workflow.

    Now, let’s test the generated code. You can run it line by line in an interactive session. If you encounter any errors or missing imports, you can make the necessary adjustments. GPT-Engineer takes care of the repetitive coding tasks.


    GPT-Engineer opens up exciting possibilities for engineers, enabling them to quickly build entire applications with a single prompt. By leveraging the power of AI, this tool dynamically generates code files, saving valuable time and effort. Through the installation and usage steps outlined in this post, you can explore the potential of GPT-Engineer and witness the transformative impact it can have on your engineering workflows. Embrace this new era of AI and unlock a world of possibilities with GPT-Engineer!
