Patronus AI is an automated AI evaluation, testing, and security platform designed to help enterprises identify hallucinations, security risks, and reliability issues in LLMs and AI agents. It replaces slower manual testing processes with automated evaluation and monitoring.

The platform can stress-test AI systems, run offline evaluations, monitor production logs, and simulate realistic environments for testing and improving AI agents.

How Patronus AI Works

  • Connect & Upload: Connect an LLM application through the self-serve API or Python SDK and upload custom datasets or evaluation criteria.
  • Evaluate & Trace: Patronus AI runs automated tests while recording model outputs and AI agent execution traces through its dashboard.
  • Score & Explain: Evaluation models such as Lynx score responses and provide explanations for failures, hallucinations, or other issues.
  • Simulate & Optimize: Advanced agentic systems can test actions in synthetic environments to improve behavior before real-world deployment.
