About Prefactor

Prefactor is an innovative evaluation layer designed for teams developing AI agents. It addresses a common challenge: many agents pass initial testing but falter in real-world production environments. By providing real-time scoring of each agent run, Prefactor enables engineering teams to detect quality regressions and model drift immediately as they occur. This continuous monitoring ensures that AI agents maintain high performance and reliability at scale, bridging the often problematic gap between development and deployment. Built specifically for teams deploying AI agents to customers, Prefactor offers a clear view of agent health, making it easier to optimize and improve AI solutions over time. Its real-time insights and scalable metrics make it a valuable tool for maintaining trustworthiness and consistency in AI-powered applications.
