FuzzyAI

82/100open sourceexplicit relation

FuzzyAI is CyberArk's Apache-2.0 framework for fuzzing LLM APIs to identify jailbreaks and related security vulnerabilities. Current README examples cover Ollama/local models, OpenAI, Anthropic, custom REST endpoints, and attacks such as ManyShot, Taxonomy, and ArtPrompt. Use it as a repeatable security-testing starting point, not a complete AI risk-management system.

Free and 100% open-source under the Apache-2.0 license. CyberArk FuzzyAI has $0 software licensing fees and no paid subscription tiers. Testing runs under a Bring Your Own Key (BYOK) model or local inference setup, with operational costs strictly determined by underlying LLM API token consumption (OpenAI, Anthropic, Azure, Bedrock, Gemini) or local GPU/CPU compute (Ollama).Review →
