R2R Integration

R2R is an all-in-one solution for AI Retrieval-Augmented Generation (RAG) with production-ready features, including multimodal content ingestion, hybrid search functionality user/document management and many more.

Overview

In this tutorial, we will:

Leverage the /rag endpoint from R2R to perform Retrieval-Augmented Generation (RAG) on a small dataset.
Evaluate the generated responses.
Analyze the traces of evaluation.

R2R Setup

Installing the Dependencies

To begin, install the necessary packages:

%pip install r2r -q

Setting up the local environment

Configure the R2R_API_KEY, OPENAI_API_KEY and RAGAS_APP_TOKEN(Optional).

from dotenv import load_dotenv

load_dotenv()

    "Cohere is well-known for its language models tailored for business use, excelling in tasks like search, summarization, and customer support. Their models are recognized for being efficient, cost-effective, and easy to integrate into workflows.",
    "AI21 Labs is famous for its Jurassic series of language models, which are highly versatile and capable of handling tasks like content creation and code generation. The Jurassic models stand out for their natural language understanding and ability to generate detailed and coherent responses.",
    "In the rapidly advancing field of artificial intelligence, several companies have made significant contributions with their large language models. Notable players include OpenAI, known for its GPT Series (including GPT-4); Anthropic, which offers the Claude Series; Google DeepMind with its Gemini Models; Meta AI, recognized for its LLaMA Series; Microsoft Azure AI, which integrates OpenAI’s GPT Models; Amazon AWS (Bedrock), providing access to various models including Claude (Anthropic) and Jurassic (AI21 Labs); Cohere, which offers its own models tailored for business use; and AI21 Labs, known for its Jurassic Series. These companies are shaping the landscape of AI by providing powerful models with diverse capabilities.",

Setting up the R2R Client

from r2r import R2RClient

client = R2RClient()

Ingesting the Data

ingest_response = client.documents.create(
    chunks=dataset,
)

Using the `/rag` Endpoint

The /rag endpoint facilitate Retrieval-Augmented Generation by integrating search results with language model outputs. The generation process can be customized using the rag_generation_config parameter, while the retrieval process can be configured using the search_settings.

query = "What makes Meta AI’s LLaMA models stand out?"

search_settings = {
        "limit": 2,
        "graph_settings": {"enabled": False, "limit": 2},
    }

response = client.retrieval.rag(
    query=query,
    search_settings=search_settings
)

print(response.results.generated_answer)

Output

Meta AI’s LLaMA models stand out due to their open-source nature, which supports innovation and experimentation by making high-quality models accessible to researchers and developers [1]. This approach democratizes AI development, fostering collaboration across industries and enabling researchers without access to expensive resources to work with advanced AI models [2].

Evaluations

Evaluating the `R2R Client` with Ragas

With the R2R Client in place, we can use Ragas r2r integration for evaluation. This process involves the following key components:

1. R2R Client and Configurations
The R2RClient and /rag configurations specifying RAG settings.
2. Evaluation Dataset
You need a Ragas EvaluationDataset that includes all necessary inputs required by Ragas metrics.
3. Ragas Metrics
Ragas provides various evaluation metrics to assess different aspects of the RAG, such as faithfulness, answer relevance, and context recall. You can explore the full list of available metrics in the Ragas documentation.

Constructing a Ragas EvaluationDataset

The EvaluationDataset is a data type in Ragas designed to represent evaluation samples. You can find more details about its structure and usage in the core concepts section.

We will use the transform_to_ragas_dataset function from ragas to get the EvaluationDataset for our data.

questions = [
    "Who are the major players in the large language model space?",
    "What is Microsoft’s Azure AI platform known for?",
    "What kind of models does Cohere provide?",
]

references = [
    "The major players include OpenAI (GPT Series), Anthropic (Claude Series), Google DeepMind (Gemini Models), Meta AI (LLaMA Series), Microsoft Azure AI (integrating GPT Models), Amazon AWS (Bedrock with Claude and Jurassic), Cohere (business-focused models), and AI21 Labs (Jurassic Series).",
    "Microsoft’s Azure AI platform is known for integrating OpenAI’s GPT models, enabling businesses to use these models in a scalable and secure cloud environment.",
    "Cohere provides language models tailored for business use, excelling in tasks like search, summarization, and customer support.",
]

r2r_responses = []

search_settings = {
    "limit": 2,
    "graph_settings": {"enabled": False, "limit": 2},
}

for que in questions:
    response = client.retrieval.rag(query=que, search_settings=search_settings)
    r2r_responses.append(response)

from ragas.integrations.r2r import transform_to_ragas_dataset

ragas_eval_dataset = transform_to_ragas_dataset(
    user_inputs=questions, r2r_responses=r2r_responses, references=references
)

Output

EvaluationDataset(features=['user_input', 'retrieved_contexts', 'response', 'reference'], len=3)

Selecting the Metrics

To evaluate our RAG endpoint, we will use the following metrics:

Response Relevancy: Measures how relevant a response is to the user’s input (query).
Context Precision: Measures how many of the relevant documents (or pieces of information) were successfully retrieved.
Faithfulness: Measures how factually consistent a response is with the retrieved context.

from ragas.metrics import AnswerRelevancy, ContextPrecision, Faithfulness
from ragas import evaluate
from langchain_openai import ChatOpenAI
from ragas.llms import LangchainLLMWrapper

llm = ChatOpenAI(model="gpt-4o-mini")
evaluator_llm = LangchainLLMWrapper(llm)

ragas_metrics = [AnswerRelevancy(llm=evaluator_llm ), ContextPrecision(llm=evaluator_llm ), Faithfulness(llm=evaluator_llm )]

results = evaluate(dataset=ragas_eval_dataset, metrics=ragas_metrics)

Output
