Patronus AI

Patronus AI is a research lab developing training data and simulated environments for frontier AI. Its work spans reinforcement learning environments and digital world models for agents operating in software.

Frontier labs buy tasks (with reference solutions, rubrics and graders) and simulated applications that run inside their own training infrastructure, for mid-training and reinforcement learning. Ready-built environments cover software development, computer use and knowledge work. Pricing is not published.
