gpt-engineer

gpt-engineer lets you:

Specify software in natural language
Sit back and watch as an AI writes and executes the code
Ask the AI to implement improvements

Getting Started

Install gpt-engineer

For stable release:

python -m pip install gpt-engineer

For development:

git clone https://github.com/gpt-engineer-org/gpt-engineer.git
cd gpt-engineer
poetry install
poetry shell to activate the virtual environment

We actively support Python 3.10 - 3.12. The last version to support Python 3.8 - 3.9 was 0.2.6.

Setup API key

Choose one of:

Export env variable (you can add this to .bashrc so that you don't have to do it each time you start the terminal)
- export OPENAI_API_KEY=[your api key]
.env file:
- Create a copy of .env.template named .env
- Add your OPENAI_API_KEY in .env
Custom model:
- See docs, supports local model, azure, etc.

Check the Windows README for Windows usage.

Other ways to run:

Use Docker (instructions)
Do everything in your browser:

Create new code (default usage)

Create an empty folder for your project anywhere on your computer
Create a file called prompt (no extension) inside your new folder and fill it with instructions
Run gpte <project_dir> with a relative path to your folder
- For example: gpte projects/my-new-project from the gpt-engineer directory root with your new folder in projects/

Improve existing code

Locate a folder with code which you want to improve anywhere on your computer
Create a file called prompt (no extension) inside your new folder and fill it with instructions for how you want to improve the code
Run gpte <project_dir> -i with a relative path to your folder
- For example: gpte projects/my-old-project -i from the gpt-engineer directory root with your folder in projects/

Benchmark custom agents

gpt-engineer installs the binary 'bench', which gives you a simple interface for benchmarking your own agent implementations against popular public datasets.
The easiest way to get started with benchmarking is by checking out the template repo, which contains detailed instructions and an agent template.
Currently supported benchmark:
- APPS
- MBPP

By running gpt-engineer, you agree to our terms.

Relation to gptengineer.app (GPT Engineer)

gptengineer.app is a commercial project for the automatic generation of web apps. It features a UI for non-technical users connected to a git-controlled codebase. The gptengineer.app team is actively supporting the open source community.

Features

Pre Prompts

You can specify the "identity" of the AI agent by overriding the preprompts folder with your own version of the preprompts. You can do so via the --use-custom-preprompts argument.

Editing the preprompts is how you make the agent remember things between projects.

Vision

By default, gpt-engineer expects text input via a prompt file. It can also accept image inputs for vision-capable models. This can be useful for adding UX or architecture diagrams as additional context for GPT Engineer. You can do this by specifying an image directory with the —-image_directory flag and setting a vision-capable model in the second CLI argument.

E.g. gpte projects/example-vision gpt-4-vision-preview --prompt_file prompt/text --image_directory prompt/images -i

Open source, local and alternative models

By default, gpt-engineer supports OpenAI Models via the OpenAI API or Azure OpenAI API, as well as Anthropic models.

With a little extra setup, you can also run with open source models like WizardCoder. See the documentation for example instructions.

Mission

The gpt-engineer community mission is to maintain tools that coding agent builders can use and facilitate collaboration in the open source community.
