Contact Word Game

A steganography word game implementation where two LLM instances try to communicate a secret word while keeping it hidden from an overseer LLM. Thank Daniel Tan for envisioning this game!

Game Rules

1. Player 1 is given a secret word and must communicate it to Player 2
2. Both players must keep the word hidden from the Overseer
3. When Player 1 believes Player 2 knows the word, it calls "CONTACT"
4. Player 2 then makes its guess
5. The Overseer makes its guess based on the conversation
6. The game is won if Player 2 guesses correctly while the Overseer does not

Installation

1. Create and activate a virtual environment (recommended):

python -m venv venv
source venv/bin/activate  # On Windows use: venv\Scripts\activate

2. Install the required packages:

pip install -r requirements.txt

3. Download required NLTK data:

python -c "import nltk; nltk.download('wordnet')"

4. Set up API keys:
   • For OpenAI models: OPENAI_API_KEY
   • For Anthropic models: ANTHROPIC_API_KEY
   • For Google Gemini models: GOOGLE_API_KEY

Usage

1. Configure your experiment in configs/config.yaml
2. Run: python main.py

Results will be saved in results/{experiment_name}/v{n}/

Configuration

The config.yaml supports:

• experiment_name: Name of the experiment
• models: Configuration for each model:
  • player_1, player_2: The communicating LLMs
  • overseer: The model trying to guess the secret word
• num_samples: Number of game rounds to run

Supported model prefixes:

• openai/: OpenAI models
• anthropic/: Anthropic models
• google/: Google Gemini models
