The record

Purpose: RAGChecker is an automatic evaluation framework for assessing and diagnosing retrieval-augmented generation systems.
Pipeline metrics: It provides overall metrics for the RAG pipeline and diagnostic metrics for retrieval and generation components.
Fine-grained evaluation: Its fine-grained evaluation uses claim-level entailment operations.
Retriever metrics: Documented retriever metrics include claim recall and context precision.
Generator metrics: Documented generator metrics include context utilization, noise sensitivity, hallucination, self-knowledge, and faithfulness.
Benchmark: The repository says its benchmark was released and links a guide for using it.
Input requirement: For each query, the only required annotation is the ground-truth answer; generated responses and retrieved context are also accepted in the input format.
Installation: The maker documents installation with pip install ragchecker and requires downloading the spaCy en_core_web_sm model in its quick start.
Usage: The framework can be run through a CLI or Python API, with selectable metric groups or all metrics.
Model setup: The example pipeline uses configurable extractor and checker models and documents an AWS Bedrock Llama 3 70B example.
Integration: The README documents an integration with LlamaIndex for evaluating RAG applications built with it.
License: The project is licensed under Apache-2.0.
Security reporting: The contribution guide asks users to report potential security issues to AWS/Amazon Security through its vulnerability reporting page rather than public GitHub issues.
Support and contributions: The project directs bug reports and feature requests to its GitHub issue tracker and welcomes pull requests.
