The README presents garak as a scanner that checks whether an LLM-backed application can be made to fail, using static, dynamic and adaptive probes.

Source: https://github.com/nvidia/garak

What it supplies: The README presents garak as a scanner that checks whether an LLM-backed application can be made to fail, using static, dynamic and adaptive probes.

Useful for: - Probe a model or chatbot you are authorised to test for hallucination, data leakage, prompt injection or toxicity.
- Scan models from Hugging Face, OpenAI, Bedrock, LiteLLM, REST endpoints or GGUF files.
- List the available probes and select a probe spec for a run.

First action: - Install with python -m pip install -U garak, or use a Conda environment and an editable install from source.
- Run garak --list_probes to see the probes.
- Run garak with a target type, target name and probe spec as in the README examples.

Prerequisites and limits: The README says garak is a command-line tool developed in Linux and OSX, and its Conda example uses Python 3.11 or later up to 3.14. Hosted targets need their own API access.

- The README is an index to the user guide, which was not read.
- Probe results depend on the target and probe set chosen.
- Hosted targets may incur provider charges.

Source-documented: the README ends with an Apache licence v2 statement. Scan only systems you own or are authorised to test, and follow each provider's terms.

Written from the README text only. Statements are as the README gives them; nothing was installed or run.
Based on README text only; the user guide, probe lists and code were not read. No install or scan was made.
