aidu-ai-llm

Small Python LLM playground from PHBern to help people to understand how to build AI-Tutors

with:

• reusable LLM utilities under src/aidu/ai/llm
• a FastAPI chat backend in serve/app.py
• a minimal Vite frontend in web/

Quick Example

pip install aidu-ai-llm aidu-support

then run the example app:

aidu-ai-llm-example

Development Prerequisites

The following tools are required to build and run the project:

• make — for running common development and build tasks
• Python (>=3.11) — backend runtime
• uv (latest) — Python package manager and environment runner
• Node.js (>=18, includes npm) — required to build the frontend (TypeScript via Vite)

💡 Notes

• uv replaces pip, venv, etc. → state of the art: no manual environment activation needed
• npm is included with Node.js, so you don’t need to install it separately

Quick Start

Copy .env_example to .env and add your OpenAI Token there.

When you have ensured the prerequisites, this should work. Clean up, install dependencies, build frontend, and run the server:

make clean          # clean up python backend and web frontend
make web.install    # install web frontend dependencies
make web.build      # build web frontend
make install        # install python dependencies
make serve          # run FastAPI server

Open: http://localhost:8000

Then you can interact with the chat interface.
