Patronus AI

Patronus AI, founded in 2023, builds evaluation infrastructure for large language models, including the open Lynx hallucination-detection model, the FinanceBench benchmark of 10,000 question-answer pairs for financial-document Q&A, and GLIDER, an evaluation model that produces explainable reasoning chains for guardrail use cases. The company has since expanded into simulated digital environments for training and evaluating AI agents.
