Probe a model or agent stack with adversarial test suites so safety failures show up before deployment or review.

## Prerequisites

Python 3.10+, target LLM or API credentials, command line access

## Installation

Use the upstream install or setup path that matches your environment:
- ### Standard install with pip
- python -m pip install -U garak
- python -m pip install -U git+https://github.com/NVIDIA/garak.git@main
- conda create --name garak "python>=3.10,<=3.12"

- garak is a command-line tool. It's developed in Linux and OSX.
- Just grab it from PyPI and you should be good to go:
- The standard pip version of garak is updated periodically. To get a fresher version from GitHub, try:
