Using Azure OpenAI

This tutorial will show you how to use Azure OpenAI endpoints instead of OpenAI endpoints.


this guide is for folks who are using the Azure OpenAI endpoints. Check the evaluation guide if your using OpenAI endpoints.

Load sample dataset

# data
from datasets import load_dataset

amnesty_qa = load_dataset("explodinggradients/amnesty_qa", "english_v2")
Found cached dataset fiqa (/home/jjmachan/.cache/huggingface/datasets/explodinggradients___fiqa/ragas_eval/1.0.0/3dc7b639f5b4b16509a3299a2ceb78bf5fe98ee6b5fee25e7d5e4d290c88efb8)
    baseline: Dataset({
        features: ['question', 'ground_truth', 'answer', 'contexts'],
        num_rows: 30

Lets import metrics that we are going to use. To learn more about what each metrics do, check out this doc

from ragas.metrics import (
from ragas.metrics.critique import harmfulness

# list of metrics we're going to use
metrics = [

Configuring them for Azure OpenAI endpoints

Ragas also uses AzureOpenAI for running some metrics so make sure you have your Azure OpenAI key, base URL and other information available in your environment. You can check the langchain docs or the Azure docs for more information.

But basically you need the following information.

azure_configs = {
    "base_url": "https://<your-endpoint>",
    "model_deployment": "your-deployment-name",
    "model_name": "your-model-name",
    "embedding_deployment": "your-deployment-name",
    "embedding_name": "text-embedding-ada-002",  # most likely
import os

# assuming you already have you key available via your environment variable. If not use this
# os.environ["AZURE_OPENAI_API_KEY"] = "..."

Now lets create the chat model and embedding model instances so that ragas can use it for evaluation.

from langchain_openai.chat_models import AzureChatOpenAI
from langchain_openai.embeddings import AzureOpenAIEmbeddings
from ragas import evaluate

azure_model = AzureChatOpenAI(

# init the embeddings for answer_relevancy, answer_correctness and answer_similarity
azure_embeddings = AzureOpenAIEmbeddings(

In case of any doubts on how to configure the Azure endpont through langchain do reffer to the AzureChatOpenai and AzureOpenAIEmbeddings documentations from the langchain docs.


Running the evalutation is as simple as calling evaluate on the Dataset with the metrics of your choice.

result = evaluate(
    amnesty_qa["eval"], metrics=metrics, llm=azure_model, embeddings=azure_embeddings

{'faithfulness': 0.7083, 'answer_relevancy': 0.9416, 'context_recall': 0.7762, 'context_precision': 0.8000, 'harmfulness': 0.0000}

and there you have the it, all the scores you need.

now if we want to dig into the results and figure out examples where your pipeline performed worse or really good you can easily convert it into a pandas array and use your standard analytics tools too!

df = result.to_pandas()
