## 🚧 2025 Tournament Rebuild in Progress 🚧
**This project is currently being rebuilt and enhanced for the 2025 NCAA Tournament. Stay tuned for major updates!**
---
Quick hobby hack to made a march madness bracket simulator as I was too lazy to fill one out online. It's probably terrible but was fun to put together. Utilizes the openai function calling to extract a single winner from provided matchups as the tournament progresses. Can also run a quick random or seed based decider. For AI decisions, you can input custom instructions such as "pick teams with a dog mascot".
---
##### Update 2024-04-01: frontend website launched
Put this app behind fastapi and hosted a React page!
The new frontend provides a cool inferface for simulating the March Madness tournament. It communicates with Python using fastAPI and websockets to run the simulations and display the results in real-time.
View here: [https://marchmadness.drose.io](https://marchmadness.drose.io)
For more details about the frontend implementation, please refer to the [frontend README](frontend/README.md).

## Features
- Realistic Simulations: The simulator uses advanced decision-making functions to determine the winner of each matchup, taking into account factors such as team rankings, historical performance, and more.
- Multiple Decision Functions: Choose from three different decision functions to determine the outcome of each game: AI-powered decisions using OpenAI's GPT-3.5, seed-based decisions, or random winner selection.
- Detailed Bracket Visualization: The simulator provides a clear and concise representation of the bracket, displaying the progress of the tournament from the Round of 64 to the Championship game.
- Customizable Initial Bracket: Load your own initial bracket data from a JSON file to simulate different tournament scenarios.
- State Persistence: Save and load the current state of the tournament, allowing you to resume the simulation from where you left off.
## Getting Started
### Prerequisites
- [uv](https://github.com/astral-sh/uv) (Python)
- [bun](https://bun.sh) (frontend)
- [Infisical CLI](https://infisical.com/docs/cli/overview) (`brew install infisical/get-infisical/infisical`)
### Setup
```bash
git clone https://github.com/cipher982/march-madness-llm
infisical login # once — opens browser
```
### Run locally
```bash
# Backend
cd backend
infisical run --env dev -- uv run uvicorn mm_ai.main:app --reload --port 8000
# Frontend
cd frontend
infisical run --env dev -- bun run start
# Tests
cd backend
infisical run --env dev -- uv run pytest
```
No `.env` files, no Keychain setup, no direnv. Secrets live in Infisical (project: `march-madness-llm`).
## Project Structure
The project consists of three main files:
- `main.py`: The entry point of the application. It sets up the argument parser, creates the bracket, and runs the simulation.
- `deciders.py`: Contains the decision functions used to determine the winner of each matchup, including the AI-powered decision using OpenAI's GPT-3.5.
- `bracket.py`: Defines the classes for the bracket structure, including Team, Matchup, Round, Region, and Bracket. It also provides methods for loading initial data, updating the bracket state, and visualizing the bracket.
