About

garak is an open-source LLM vulnerability scanner, developed by NVIDIA and the community, for finding ways an LLM or dialog system can fail. It probes for hallucination, data leakage, prompt injection, misinformation, toxicity and jailbreaks, and produces a report of what worked. It is a command-line tool that can target Hugging Face models, OpenAI, AWS Bedrock, LiteLLM and anything reachable over REST.

Use cases: security-scanning, llm-evaluation
