Patronus AI
Enterprise AI evaluation platform for automated testing, hallucination detection, and continuous monitoring of LLM applications
Overview
Patronus AI is an enterprise-grade evaluation platform that helps companies test, monitor, and secure their LLM applications before and after deployment. Founded in 2023 by former Meta AI researchers, Patronus provides automated evaluators for hallucination detection, RAG accuracy, toxicity filtering, PII leakage, and regulatory compliance. The platform offers both pre-deployment testing suites and real-time production monitoring, enabling enterprises to catch AI failures before they reach customers. Patronus has built specialized evaluation models including Lynx (for RAG hallucination detection) and provides industry-specific compliance evaluators for regulated sectors like finance and healthcare.
The Verdict
