Overview
Judgment Labs builds AI reliability infrastructure. Its core offering is an agent behavior monitoring (ABM) platform paired with the open-source Judgeval framework, which traces an AI agent’s entire production workflow—logging LLM calls, tool usage, and memory. It provides automated behavior classification, real-time alerts, and dashboards to track latency and cost, helping teams observe and improve multi-step AI workflows. By allowing rules or human scoring to define correct behavior, it aims to enable safe deployment and continuous improvement of reliable autonomous agents in high-stakes sectors like legal, finance, and enterprise support.
