What is Cleanlab?
Cleanlab is an AI safety and reliability platform that helps teams monitor, guardrail, evaluate and remediate failures in their AI applications. Its documentation covers three products: the Cleanlab AI Platform, Cleanlab TLM (Trustworthy Language Model) and Cleanlab Studio.
TLM provides automated evaluation and hallucination detection for LLM outputs, returning a trustworthiness score and an explanation for each response. Studio focuses on finding and fixing errors in real-world datasets, so unreliable data can be turned into more reliable models and insights. The docs offer tutorials, sample code, developer guides and API references for building with these tools.
