Building an Agentic System to enhance RAG with Self-Grading and Web Search Capabilities using Pydantic.AI, Groq and Langchain
Introduction
Retrieval-Augmented Generation (RAG) systems have become increasingly important in building reliable AI applications. In this article, we’ll explore building an advanced RAG system that combines local document retrieval with dynamic web search capabilities and self-grading mechanisms using Pydantic.ai and Groq.
PydanticAI
PydanticAI is a Python Agent Framework designed to make it less painful to build production grade applications with Generative AI.
Why use PydanticAI
- Built by the team behind Pydantic (the validation layer of the OpenAI SDK, the Anthropic SDK, LangChain, LlamaIndex, AutoGPT, Transformers, CrewAI, Instructor and many more)
- Model-agnostic — currently OpenAI, Gemini, Anthropic, and Groq are supported, and there is a simple interface to implement support for other models.
- Type-safe
- Control flow and agent composition is done with vanilla Python, allowing you to make use of the same Python development best practices you’d use in any other (non-AI) project
- Structured response validation with Pydantic
- Streamed responses, including validation of streamed structured responses with Pydantic
- Novel, type-safe dependency injection system, useful for testing and eval-driven iterative development
- Logfire integration for debugging and monitoring the performance and general behavior of your LLM-powered application
Technology Stack
Our system leverages several modern AI technologies:
Core Components:
- Pydantic.ai for type-safe AI agents
- Groq’s llama-3.3-70b-versatile model for LLM inference
- LangChain for document processing
- ChromaDB and HuggingFace embeddings
- Tavily for web search
Supporting Libraries:
- sentence-transformers for embeddings
- PyPDF for document loading\
- nest_asyncio for async operations in Jupyter
System Architecture
1. Document Processing and Indexing
# Document loading and chunking
loader = PyPDFLoader("path/to/document.pdf")
documents = loader.load()
# Text splitting
split_docs = RecursiveCharacterTextSplitter(
chunk_size=500,
chunk_overlap=50
).split_documents(documents)
# Vector store creation
vectorstore = Chroma.from_documents(
documents=split_docs,
embedding=embedding,
persist_directory=persist_directory
)
2. Agent Configuration
The system uses a sophisticated agent setup with multiple capabilities
groq_agent = Agent(
groq_model,
deps_type=Deps,
retries=2,
result_type=str,
system_prompt="""You are a Helpful Assistant Proficient in
Answering concise, factual and to the point answers..."""
)
3. Retrieval Tool
The system includes a custom retrieval tool for accessing local documents:
@groq_agent.tool
async def retriever_tool(ctx: RunContext[Deps], question: str) -> List[str]:
load_vectorstore = Chroma(
persist_directory=persist_directory,
embedding_function=embedding
)
docs = load_vectorstore.similarity_search(question, k=3)
return [d.page_content for d in docs]
4. Web Search Integration
A web search tool is implemented using Tavily:
@groq_agent.tool_plain
async def websearch_tool(question) -> str:
tavily_client = TavilyClient()
answer = tavily_client.qna_search(query=question)
return answer
Key Features
1. Self-Grading Mechanism
The system evaluates its own responses based on three criteria:
- Relevancy (0–1)
- Faithfulness to context (0–1)
- Context quality (0–1)
{
"Relevancy": 0.9,
"Faithfulness": 0.95,
"Context Quality": 0.85,
"Needs Web Search": false,
"Explanation": "Response directly addresses the question..."
}
2. Dynamic Context Augmentation
The system can automatically decide when to augment local knowledge with web search:
if grades["Needs Web Search"]:
web_results = await websearch_tool(query)
# Augment context with web results
3. Structured Dependencies
Using Pydantic for type safety:
@dataclass
class Deps:
question: str | None
context: str | None
Code Implementation
- Install required dependencies
%pip -q install pydantic-ai
%pip -q install nest_asyncio
%pip -q install devtools
%pip install 'pydantic-ai-slim[openai,groq,logfire]'
%pip install tavily-python
%pip install -qU langchain
%pip install -qU langchain_community
%pip install -qU sentence_transformers
%pip install -qU langchain_huggingface
%pip install pypdf
2. Set up the API keys in google colab
from google.colab import userdata
import os
os.environ["OPENAI_API_KEY"] = userdata.get('OPENAI_API_KEY')
os.environ["GROQ_API_KEY"] = userdata.get('GROQ_API_KEY')
3. Instantiate LLM
from pydantic_ai import Agent
from pydantic_ai.models.openai import OpenAIModel
from pydantic_ai.models.groq import GroqModel
openai_model = OpenAIModel('gpt-4o-mini')
groq_model = GroqModel("llama-3.3-70b-versatile")
4. Load required documents and build index
from langchain_community.vectorstores import Chroma
from langchain_community.embeddings import HuggingFaceEmbeddings
from langchain.document_loaders import PyPDFLoader
from langchain.text_splitter import RecursiveCharacterTextSplitter
#
loader = PyPDFLoader("/content/data/Fibromyalgia_Final.pdf")
documents = loader.load()
#
split_docs = RecursiveCharacterTextSplitter(chunk_size=500, chunk_overlap=50).split_documents(documents)
#
#embeddings
embedding = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
#
#Build Index
vectorstore = Chroma.from_documents(
documents=split_docs,
embedding=embedding,
persist_directory=persist_directory,
collection_name="fibromyalgia"
)
#
5. Define Dependencies
PydanticAI uses a dependency injection system to provide data and services to your agent’s.Dependencies can be any python type. While in simple cases you might be able to pass a single object as a dependency (e.g. an HTTP connection), dataclasses are generally a convenient container when your dependencies included multiple objects.
from dataclasses import dataclass
@dataclass
class Deps:
question:str |None
context:str |None
6. Instantiate pydantic.ai Agent
Agents are PydanticAI’s primary interface for interacting with LLMs.
In some use cases a single Agent will control an entire application or component, but multiple agents can also interact to embody more complex workflows.
The Agent class has full API documentation, but conceptually you can think of an agent as a container for:
- A system prompt — a set of instructions for the LLM written by the developer
- One or more function tool — functions that the LLM may call to get information while generating a response
- An optional structured result type — the structured datatype the LLM must return at the end of a run
- A dependency type constraint — system prompt functions, tools and result validators may all use dependencies when they’re run
- Agents may optionally also have a default LLM model associated with them; the model to use can also be specified when running the agent
import nest_asyncio
nest_asyncio.apply()
#
groq_agent = Agent(groq_model,
deps_type=Deps,
retries=2,
result_type=str,
system_prompt=("You are a Helpful Assiatnt Profiocient in Answering concise,factful and to the point asnwers for questions asked based on the Context provided"
"You have to Use the `retrievre_tool' to get relevent context and generate response based on the context retrieved"
"""You are a grading assistant. Evaluate the response based on:
1. Relevancy to the question
2. Faithfulness to the context
3. Context quality and completeness
lease grade the following response based on:
1. Relevancy (0-1): How well does it answer the question?
2. Faithfulness (0-1): How well does it stick to the provided context?
3. Context Quality (0-1): How complete and relevant is the provided context?
Question: {ctx.deps.query}
Context: {ctx.deps.context}
Response: {ctx.deps.response}
Also determine if web search is needed to augment the context.
Provide the grades and explanation in the JSON format with key atrributes 'Relevancy','Faithfulness','Context Quality','Needs Web Search':
{"Relevancy": <score>,
"Faithfulness": <score>,
"Context Quality": <score>,
"Needs Web Search": <true/false>,
"Explanation": <explanation>,
"Answer":<provide response based on the context from the `retrievre_tool' if 'Need Web Search' value is 'false' otherwise Use the `websearch_tool` function to generate the final reaponse}"""
),
)
7.Function Tools
Function tools provide a mechanism for models to retrieve extra information to help them generate a response.
They’re useful when it is impractical or impossible to put all the context an agent might need into the system prompt, or when you want to make agents’ behavior more deterministic or reliable by deferring some of the logic required to generate a response to another (not necessarily AI-powered) tool.
Function tools are basically the “R” of RAG (Retrieval-Augmented Generation) — they augment what the model can do by letting it request extra information.
The main semantic difference between PydanticAI Tools and RAG is RAG is synonymous with vector search, while PydanticAI tools are more general-purpose.
There are a number of ways to register tools with an agent:
- via the
@agent.tool
decorator — for tools that need access to the agent context - via the
@agent.tool_plain
decorator — for tools that do not need access to the agent context - via the
tools
keyword argument toAgent
which can take either plain functions, or instances ofTool
8. Create Web Search tool
@groq_agent.tool_plain
async def websearch_tool(question) -> str:
"""check if the square is a winner"""
# Step 1. Instantiating your TavilyClient
tavily_client = TavilyClient()
# Step 2. Executing a Q&A search query
answer = tavily_client.qna_search(query=question)
# Step 3. That's it! Your question has been answered!
print(f"WEB SEARCH:{answer}")
return answer
9. Create Retriever Tool
@groq_agent.tool
async def rertiever_tool( ctx: RunContext[Deps],question:str)-> List[str]:
load_vectorstore = Chroma(persist_directory=persist_directory, embedding_function=embedding,collection_name="fibromyalgia")
docs = load_vectorstore.similarity_search(question,k=3)
documnets = [d.page_content for d in docs]
print(f"RAG Retrieval:{documnets}")
return documnets
10. Results — Invoke the agent
Results are the final values returned from running an agent. The result values are wrapped in RunResult
and StreamedRunResult
so you can access other data like cost of the run and message history. Runs end when either a plain text response is received or the model calls a tool associated with one of the structured result types
Question1
query = "What is Fibromyalgia?"
response = groq_agent.run_sync(query)
print(response)
