Govchat

Govchat is an open source chat UI for AI models. It is based on an old version of Chatbot-ui.

Chatbot UI

Version system: Version yy.0m.micro

Deploy

Docker

Build locally:

docker build -t chatgpt-ui .
docker run -e OPENAI_API_KEY=xxxxxxxx -p 3000:3000 chatgpt-ui

Running Locally

1. Clone Repo

git clone ...

2. Install Dependencies

npm i

3. Provide OpenAI API Key

Create a .env.local file in the root of the repo with your OpenAI API Key:

OPENAI_API_KEY=YOUR_KEY

You can set OPENAI_API_HOST where access to the official OpenAI host is restricted or unavailable, allowing users to configure an alternative host for their specific needs.

Additionally, if you have multiple OpenAI Organizations, you can set OPENAI_ORGANIZATION to specify one.

4. Run App

npm run dev

5. Use It

You should be able to start chatting.

Configuration

When deploying the application, the following environment variables can be set:

OPENAI_API_KEY The default API key used for authentication with OpenAI. Set this to a fake value when using APIM.
OPENAI_API_HOST https://api.openai.com The base url, for Azure use https://<endpoint>.openai.azure.com. If using APIM enter the URI of the APIM instance. When using APIM set to the APIM URL for the Azure Open AI.
