Objective metrics, intelligent test generation, and data-driven insights for LLM apps

Ragas is your ultimate toolkit for evaluating and optimizing Large Language Model (LLM) applications. Say goodbye to time-consuming, subjective assessments and hello to data-driven, efficient evaluation workflows. Don't have a test dataset ready? We also do production-aligned test set generation.

Key Features

• 🎯 Objective Metrics: Evaluate your LLM applications with precision using both LLM-based and traditional metrics.
• 🧪 Test Data Generation: Automatically create comprehensive test datasets covering a wide range of scenarios.
• 🔗 Seamless Integrations: Works flawlessly with popular LLM frameworks like LangChain and major observability tools.
• 📊 Build feedback loops: Leverage production data to continually improve your LLM applications.

:shield: Installation

Pypi:

pip install ragas

Alternatively, from source:

pip install git+https://github.com/explodinggradients/ragas

:fire: Quickstart

Evaluate your RAG with Ragas metrics

This is 4 main lines:

from ragas.metrics import LLMContextRecall, Faithfulness, FactualCorrectness
from langchain_openai.chat_models import ChatOpenAI
from ragas.llms import LangchainLLMWrapper

evaluator_llm = LangchainLLMWrapper(ChatOpenAI(model="gpt-4o"))
metrics = [LLMContextRecall(), FactualCorrectness(), Faithfulness()]
results = evaluate(dataset=eval_dataset, metrics=metrics, llm=evaluator_llm)

Generate a test dataset for comprehensive RAG evaluation

What if you don't have the data for folks asking questions when they interact with your RAG system?

Ragas can help by generating synthetic test set generation -- where you can seed it with your data and control the difficulty, variety, and complexity.
