A Next.js LLM Chat UI for function calling using the OpenAI Assistants API.

Features

• OpenAI Assistants API
• Function calling support
• Confirmation mechanism for function calls (using __CONFIRM suffix)
• Custom rendering components for function outputs (using __{ComponentName} syntax)
• Python server for code execution using Autogen's DockerCommandLineCodeExecutor

See src/app/assistants/time-assistant.ts for an example assistant.

Setup

Installation and Configuration

1. Rename .env.example to .env and set up your OpenAI API key.

2. Install dependencies and launch the Chat UI:

   npm install
   npm run dev
   

3. (Optional) Set up and launch the Python server:

   npm run install-python-server
   npm run launch-python-server
   

   Alternative:

   python3 -m venv ./.venv && .venv/bin/pip install -r ./requirements.txt
   ./.venv/bin/python ./server.py
   

Usage

After starting the development server, navigate to http://localhost:3000 in your web browser to access the Chat UI.

Use the refresh button to regenerate assistants. Assistants are currently identified by name - so names must be unique.
