About
Cleanlab is an AI reliability platform that helps organizations deploy trustworthy AI agents in production. Its core product, Codex, detects and remediates incorrect responses from AI agents in real time — catching hallucinations, retrieval errors, knowledge gaps, policy violations, and malicious use before they reach end users. The platform provides a human-in-the-loop workflow that empowers non-technical subject matter experts to improve AI responses and fix knowledge base issues without writing code. Cleanlab also offers an open-source Python library (11,000+ GitHub stars) that is the standard data-centric AI package for finding and fixing label errors in machine learning datasets. It deploys as an independent layer alongside any AI system, available as SaaS or via VPC. Trusted by BBVA, Tencent, Amazon, Oracle, Red Hat, Google, and iRobot.
