# GABM: Generative Agent-Based Model

[GABM](https://github.com/compolis/GABM/) is a flexible, extensible [Python](https://www.python.org/) framework for developing agent-based models that use large language models (LLMs) as agent reasoning engines. It supports use of multiple LLM providers and implements persistent response caching.

## Features
- Flexible, extensible agent-based modeling with LLMs
- Multi-provider LLM support
- Persistent response caching

## API Keys
You need a `data/api_key.csv` file with your API keys. This file is not included in the repository for security reasons.


Create `data/api_key.csv` yourself in the following CSV format:


You must sign up with each LLM provider to obtain an API key:

- **OpenAI:** Go to [platform.openai.com/signup](https://platform.openai.com/signup) and create an account. After logging in, visit [API Keys](https://platform.openai.com/api-keys) to generate a key. Use `openai` as the API name.
- **DeepSeek:** Register at [deepseek.com](https://deepseek.com/) and follow their documentation to obtain an API key. Use `deepseek` as the API name.
- **GenAI (Google):** Go to [makersuite.google.com](https://makersuite.google.com/) and sign in with your Google account. Follow instructions to get an API key. Use `genai` as the API name.
- **PublicAI (Apertus):** Sign up at [publicai.co](https://publicai.co/) to get your API key. Use `publicai` as the API name.

You can also add your [Hugging Face](https://huggingface.co/) token for downloading private or gated models:

## Installation
```bash
pip install gabm
```

## Run the Main Program
When you run GABM (e.g., with `python3 -m gabm`), the default behavior is to execute an Agent-Based Model (ABM) simulation. Here’s what happens:

### Agent Groups and Opinions

- The simulation creates three groups of agents: Negative, Positive, and Neutral.
- You can configure the number of agents in each group by editing variables at the top of the main script.
- Negative agents start with an opinion of -1.0, Positive agents with 1.0, and Neutral agents with 0.0.

### Communication Rounds

- The simulation runs for several rounds (configurable).
- In each round, agents from the Negative and Positive groups communicate with randomly selected Neutral agents.
- When a Neutral agent communicates, both the Neutral agent and the other agent update their opinions to the average of their current opinions. This models opinion mixing and convergence.

### Output and Visualization

- The simulation logs the state of the environment and the average opinion after each round to `data/logs/run_main.log`.
- After the simulation, a boxplot is generated showing the distribution of agent opinions at each round. This plot is saved to `data/output/test.png`.
- The boxplot helps visualize how opinions change and converge over time.
- The `data/logs` directory should contain `run_main.log`.

### Customization

- You can change the number of agents in each group, the number of rounds, and other parameters by editing the main script.
- The random seed is set for reproducibility, so results are consistent across runs unless you change the seed.

This ABM demonstration is a starting point, it does not show how LLMs can be used in an ABM yet!
