TruLens
An open-source evaluation framework for assessing and debugging large language model applications, with particular focus on RAG systems. It supports layered quantitative evaluation of both retrieval quality and generation quality, enabling systematic analysis of each component within an LLM pipeline.
Timeline (last 90 days)
Open-source evaluation frameworks such as RAGAS and TruLens package metrics like context relevance, faithfulness, and answer relevance into callable evaluation functions, which can reduce the cost of building measurement logic from scratch.
TruLens provides an observability-oriented perspective, supporting tracing and logging of the entire RAG pipeline for continuous monitoring in production environments.
Agent evaluations (Evals) fall into two categories: automated evaluation (e.g., LLM-as-judge, rule matching) and human evaluation
RAGAS and TruLens are common evaluation frameworks that can output quantitative metrics for each stage of the RAG pipeline (retrieval quality, answer faithfulness, answer relevance, etc.).
Mainstream RAG evaluation frameworks include RAGAS, TruLens, and DeepEval, which typically score across two dimensions—retrieval quality and generation quality—but lack built-in support for specialized requirements such as exact identifier matching and rule clause completeness
