LLM Question Answering over the documentation with Langchain, FAISS and OpenAI¶

Giskard is an open-source framework for testing all ML models, from LLMs to tabular models. Don’t hesitate to give the project a star on GitHub ⭐️ if you find it useful!

In this notebook, you’ll learn how to create comprehensive test suites for your model in a few lines of code, thanks to Giskard’s open-source Python library.

In this example, we illustrate the procedure using OpenAI Client that is the default one; however, please note that our platform supports a variety of language models. For details on configuring different models, visit our 🤖 Setting up the LLM Client page

This notebook presents how to implement a Question Answering system with Langchain, FAISS as a knowledge base and OpenAI embeddings. As a knowledge base we will take pdf with the SED documentation

Use-case:

QA over the SED documentation
Foundational model: “text-ada-001”
Context: the SED documentation

Outline:

Detect vulnerabilities automatically with Giskard’s scan
Automatically generate & curate a comprehensive test suite to test your model beyond accuracy-related metrics

Install dependencies¶

Make sure to install the giskard[llm] flavor of Giskard, which includes support for LLM models.

[ ]:

%pip install "giskard[llm]" --upgrade

We also install the project-specific dependencies for this tutorial.

[ ]:

%pip install openai unstructured pdf2image pdfminer-six faiss-cpu

Import libraries¶

[3]:

import os

import openai
import pandas as pd
from langchain.chains import RetrievalQA
from langchain.document_loaders import OnlinePDFLoader
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.vectorstores import FAISS
from langchain_openai import OpenAI, OpenAIEmbeddings

from giskard import Model, scan

Notebook settings¶

[4]:

# Set the OpenAI API Key environment variable.
OPENAI_API_KEY = "..."
openai.api_key = OPENAI_API_KEY
os.environ['OPENAI_API_KEY'] = OPENAI_API_KEY

# Display options.
pd.set_option("display.max_colwidth", None)

Define constants¶

[5]:

DATA_URL = "https://www.gnu.org/software/sed/manual/sed.pdf"

LLM_NAME = "gpt-3.5-turbo-instruct"

Model building¶

Create a model with LangChain¶

Now we create our model with langchain, using the RetrievalQA class:

[6]:

def get_context_storage() -> FAISS:
    """Initialize a vector storage with the context."""
    text_splitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
    docs = OnlinePDFLoader(DATA_URL).load_and_split(text_splitter)
    embeddings = OpenAIEmbeddings(openai_api_key=OPENAI_API_KEY)
    db = FAISS.from_documents(docs, embeddings)
    return db


# Create the chain.
llm = OpenAI(
    openai_api_key=OPENAI_API_KEY,
    request_timeout=20,
    max_retries=100,
    temperature=0.2,
    model_name=LLM_NAME,
)
qa = RetrievalQA.from_chain_type(llm=llm, chain_type="stuff", retriever=get_context_storage().as_retriever())

Detect vulnerabilities in your model¶

Wrap model and dataset with Giskard¶

Before running the automatic LLM scan, we need to wrap our model into Giskard’s Model object.

[ ]:

giskard_model = Model(
    model=qa,
    # A prediction function that encapsulates all the data pre-processing steps and that could be executed with the dataset used by the scan.
    model_type='text_generation',  # Either regression, classification or text_generation.
    name="GNU sed, a stream editor",  # Optional.
    description="A model that can answer any information found inside the sed manual.",
    # Is used to generate prompts during the scan.
    feature_names=['query'],  # Default: all columns of your dataset.
)

Scan your model for vulnerabilities with Giskard¶

We can now run Giskard’s scan to generate an automatic report about the model vulnerabilities. This will thoroughly test different classes of model vulnerabilities, such as harmfulness, hallucination, prompt injection, etc.

The scan will use a mixture of tests from predefined set of examples, heuristics, and LLM based generations and evaluations.

Since running the whole scan can take a bit of time, let’s start by limiting the analysis to the hallucination category:

[ ]:

results = scan(giskard_model)

[9]:

display(results)

Generate comprehensive test suites automatically for your model¶

Generate test suites from the scan¶

The objects produced by the scan can be used as fixtures to generate a test suite that integrates all detected vulnerabilities. Test suites allow you to evaluate and validate your model’s performance, ensuring that it behaves as expected on a set of predefined test cases, and to identify any regressions or issues that might arise during development or updates.

[10]:

test_suite = results.generate_test_suite("Test suite generated by scan")
test_suite.run()
