Know when your AI changes behavior
Regent is an innovative regression testing layer designed specifically for agentic AI applications. Unlike traditional observability tools that only log what happened, Regent focuses on detecting when and how the behavior of AI models changes over time. It allows developers to run semantic diffs on entire execution traces for critical inputs, providing insights into behavioral shifts before code changes are merged. By posting results directly into GitHub, it streamlines the workflow, helping teams identify unexpected model deviations early and prevent potential issues from reaching end users. This tool is essential for AI teams committed to maintaining reliability and consistency as their models evolve, making it a valuable addition to the AI development lifecycle. Regent's unique focus on behavioral change detection sets it apart in the landscape of observability and testing tools for AI applications, ensuring that reliability becomes a core feature, not an afterthought.
