About
TruLens is an open-source framework designed for systematically evaluating and tracking Large Language Model (LLM) experiments and AI agents. It offers fine-grained, stack-agnostic instrumentation, allowing developers to understand the performance of their LLM applications, including prompts, models, retrievers, and knowledge sources. The tool provides comprehensive evaluations to help identify failure modes and iterate on improvements. Key concepts include Feedback Functions, The RAG Triad, and Honest, Harmless, and Helpful Evals. TruLens integrates into the development workflow, enabling users to connect instrumentation and logging, define necessary feedback functions, and compare different versions of their applications through an easy-to-use user interface. It is installed via a simple pip package.
