What they say about us
As scientists and AI researchers, we spend significant time on model evaluation. The Patronus team is full of experts in this space, and brings a novel research-first approach to the problem. We're thrilled to see the increased investment in this area.
Jonathan Frankle
Chief AI Scientist at Databricks
"Evaluating LLMs is multifaceted and complex. LLM developers and users alike will benefit from the unbiased, independent perspective Patronus provides."
Max Bartolo
Command Modeling Lead at Cohere
"Testing LLMs is in its infancy. The best methods today rely on outdated academic benchmarks and noisy human evaluations -- equivalent to sticking your finger in water to get its temperature. Patronus is leading with an innovating approach."
Andriy Mulyar
Co-founder and CTO of Nomic AI
"Engineers spend a ton of time manually creating tests and grading outputs. Patronus assists with all of this and identifies exactly where LLMs break in real world scenarios."
Linus Lee
AI Lead at Notion
Patronus AI is at the forefront of multilingual AI evaluation. DefineX is excited to be using Patronus’ proprietary technology to safeguard generative AI risks in the Turkey & Middle East region and beyond.

Patronus and their straightforward API makes it really easy to reliably evaluate issues with LLMs and mitigate problems like content toxicity, PII leakage, and more. We're excited to partner with Patronus to combine their evaluation capabilities with Radiant's production reliability platform to help customers build great GenAI products.
Nitish Kulkarni
Co-founder and CEO of Radiant AI
In our mission to bring the AI stack close to enterprise data and offering best in class tools to train and deploy AI solutions, we are thrilled to partner with Patronus AI. Our combined platform will help in training, finetuning, rigorously testing, and monitoring LLM systems in a scalable way.
