Project Introduction

Summary

DeepEval is a leading open-source framework built in Python designed to empower developers and researchers to rigorously evaluate and test the performance, reliability, and safety of their Large Language Models and applications.

Problem Solved

Evaluating Large Language Models and RAG applications can be challenging, subjective, and lack standardized, reproducible methods. DeepEval provides a robust, programmatic approach to address these issues, enabling objective quality assessment.

Core Features

Comprehensive Evaluation Metrics

Offers a suite of built-in evaluation metrics (e.g., faithfulness, context relevance, answer correctness) specifically designed for LLMs and RAG applications.

Pytest Integration

Integrates seamlessly with popular testing frameworks like pytest, allowing for programmatic and reproducible evaluation directly in your development workflow.

RAG Pipeline Evaluation

Supports evaluating RAG pipelines end-to-end, from retrieval quality to answer synthesis, providing insights into component performance.

Tech Stack

Python
pytest
Pandas
Langchain (Optional)
LlamaIndex (Optional)

使用场景

DeepEval can be integrated into various stages of the LLM and RAG application lifecycle to ensure quality and performance:

Continuous Integration for LLM/RAG Apps

Details

Integrate DeepEval tests into your CI/CD pipeline to automatically evaluate RAG performance or LLM responses with every code commit, preventing regressions.

User Value

Automates quality checks, catches performance drops early, and ensures consistent reliability before deployment.

Model and Prompt Experimentation

Details

Use DeepEval's metrics to quantitatively compare the output quality when experimenting with different LLM models, prompts, or RAG configurations.

User Value

Enables data-driven decisions on which models, prompts, or configurations yield the best results for specific tasks.

Custom Evaluation & Benchmarking

Details

Develop and run custom evaluation tests tailored to your specific use-case or domain to measure quality aspects not covered by standard metrics.

User Value

Allows for highly specific and relevant quality assessment aligned with your application's unique requirements.
