GPT Lab

Description

GPT Lab is a user-friendly Streamlit app that lets users interact with and create their own AI Assistants powered by OpenAI's GPT language model. With GPT Lab, users can chat with pre-built AI Assistants or create their own by specifying a prompt and OpenAI model parameters. Our goal is to make AI accessible and easy to use for everyone, so users can focus on designing their Assistants without worrying about the underlying infrastructure.

GPT Lab is also featured in the Streamlit App Gallery among other impressive Streamlit apps.

For more insight into the development process and lessons learned while building GPT Lab, check out this blog post on the official Streamlit blog.

Accessing the app

You can access the app on the Streamlit Cloud community at gptlab.streamlit.app.

To use the app, you will need an OpenAI API key. Don't have one yet? Create one on the OpenAI website. Once you have your API key, enter it into the app when prompted.

For optimal chatting experience, we recommend using a pay-as-you-go API key. (Free trial API keys are limited to 3 requests a minute, not enough to chat with assistants.) You will need to enter your billing information here. You can learn more about OpenAI API rate limits here.

Running the app locally

To run the app locally, you will need to:

1. Set up your own Google Firestore database.
   • GPT Lab uses four main collections: users, user_hash, bots, and sessions.
   • You will need to manually set up a users collection before you can run the app locally. (All other collections will be set up by the app).
2. Clone this repository
3. Create a .streamlit/secrets.toml file containing the following:

[firestore]
db-key = "YOUR GOOGLE SERVICE ACCOUNT TOML"

[util]
global_salt = "OPTIONAL GLOBAL SALT"

• You will need to generate a service account JSON and convert that JSON file to TOML. Follow the instructions here.

4. In your terminal, set up your local environment:
   • Set up a Python virtual environment (using venv, conda, virtualenv, or any other tool you prefer)
   • Install the required Python dependencies (pip install -r app/requirements.txt)
   • Run streamlit run app/home.py

Contributions

Aside: I am new to open source, work full-time, and have young kids, please bear with me if I don't get back to you right away.
