What's RaaG?

Ever wanted to have a chat with a LLM (Large Language Model) like GPT-4o, but with the ability to ask it questions about your data? RaaG is the answer to your needs!

RaaG is the acronyme for "RAG as a GPT"

Why do we need dRAGon RaaG?​

You can already use LangChain or LlamaIndex to query your data, so why do you need RaaG?

As you know, a typical RAG application is composed of two main components with each several sub-tasks :

  1. Indexing: This involves the offline process of ingesting data from a source and indexing it.
    1. Load: The data is loaded using Document Loaders.
    2. Split: The loaded data is divided into smaller chunks using Document Splitters.
    3. Store: The chunks are stored and indexed for future searching, typically utilizing a VectorStore and an Embeddings model.
  2. Retrieval and Generation: This is the core RAG chain that operates during runtime, handling user queries.
    1. Retrieve: Relevant data chunks are fetched from the storage in response to a user query using a Retriever.
    2. Generate: A ChatModel/LLM generates an answer by incorporating the user query and the retrieved data into a prompt.

Let's say you want to build a RAG pipeline using LangChain: You would need to write code to handle each of these sub-tasks, which can be quite complex and time-consuming.

How does dRAGon RaaG simplify the process?​

So instead of having an app code like this :

from langchain import hub
from langchain_postgres.vectorstores import PGVector
from langchain_community.document_loaders import WebBaseLoader
from langchain_core.output_parsers import StrOutputParser
from langchain_core.runnables import RunnablePassthrough
from langchain_openai import OpenAIEmbeddings
from langchain_text_splitters import RecursiveCharacterTextSplitter
from langchain_openai import ChatOpenAI

os.environ["OPENAI_API_KEY"] = "YOUR_API_KEY"

loader = WebBaseLoader(
    web_paths=("https://dragon.okinawa")
)
docs = loader.load()

text_splitter = RecursiveCharacterTextSplitter(chunk_size=500, chunk_overlap=50)
splits = text_splitter.split_documents(docs)

connection = "postgresql+psycopg://user:paswword@server:5433/vectors"
collection_name = "my_rag_chunks"
embeddings = OpenAIEmbeddings()

vectorstore = PGVector(
    embeddings=embeddings,
    collection_name=collection_name,
    connection=connection,
    use_jsonb=True,
)

retriever = vectorstore.as_retriever()
prompt = hub.pull("rlm/rag-prompt")

def format_docs(docs):
    return "\n\n".join(doc.page_content for doc in docs)

llm = ChatOpenAI(model="gpt-4o")

rag_chain = (
    {"context": retriever | format_docs, "question": RunnablePassthrough()}
    | prompt
    | llm
    | StrOutputParser()
)

rag_chain.invoke("What's dRAGon?")

You will simply use the following code with a dRAGon powered RAG pipeline :

from langchain_openai import OpenAI

llm = OpenAI(
    model_name="your-dragon-raag-farm-name",
    openai_api_base="http://your.dragon.host:1985/api/raag/v1",
)

prompt = "What's dRAGon?"
llm.invoke(prompt)

dRAGon simplifies the process of building a RAG pipeline by providing a single interface to manage all these components by providing an OpenAI API compliant endpoint to interact with your RAG pipeline.
