Patronus AI

Automated evaluation and guardrails for LLM and AI agent applications

Paid

Categories: LLM, Developer Tools, Research, Automation

Patronus AI is an evaluation and monitoring platform that helps teams measure whether their LLM applications and agents actually work and stay safe in production. It provides a suite of evaluators — for hallucination, relevance, toxicity, PII leakage, context adherence, and custom criteria — including its own purpose-built judge models, so you can score outputs automatically instead of relying on manual spot checks. Teams run offline experiments to compare prompts, models, and RAG configurations, then deploy real-time guardrails that catch unsafe or off-policy responses before they reach users. Patronus also offers benchmarking datasets and tracing to debug multi-step agent runs and pinpoint where a chain went wrong. The platform exposes an API and SDK that drop into existing pipelines and CI, and it targets engineering and ML teams shipping AI features that need rigorous, repeatable quality and safety testing rather than vibes-based evaluation.
