Utility functions for Azure GenAI

Azure GenAI Utils

This repository contains a set of utilities for working with Azure GenAI. The utilities are written in Python and are designed to be used for Hackathons, Workshops, and other events where you need to quickly get started with Azure GenAI.

Requirements

• Azure Subscription
• Azure AI Foundry
• Bing Search API Key
• Python 3.8 or later
• .env file: Please do not forget to modify the .env file to match your account. Rename .env.sample to .env or copy and use it

Installation

PyPI

• pip install azure-genai-utils

From Source

• python setup.py install

Usage

Azure OpenAI Test

from azure_genai_utils.aoai_test import AOAI
aoai = AOAI()
aoai.simple_test()

PDF RAG Chain

Expand

from azure_genai_utils.rag.pdf import PDFRetrievalChain

pdf_path = "[YOUR-PDF-PATH]"

pdf = PDFRetrievalChain(
    source_uri=[pdf_path],
    loader_type="PDFPlumber",
    model_name="gpt-4o-mini",
    embedding_name="text-embedding-3-large",
    chunk_size=500,
    chunk_overlap=50,
).create_chain()

question = "[YOUR-QUESTION]"
docs = pdf.retriever.invoke(question)
results = pdf.chain.invoke({"chat_history": "", "question": question, "context": docs})

Bing Search

Expand

from azure_genai_utils.tools import BingSearch
from dotenv import load_dotenv

# You need to add BING_SUBSCRIPTION_KEY=xxxx in .env file
load_dotenv()

# Basic usage
bing = BingSearch(max_results=2, locale="ko-KR")
results = bing.invoke("Microsoft AutoGen")
print(results)

## Include news search results and format output
bing = BingSearch(
    max_results=2,
    locale="ko-KR",
    include_news=True,
    include_entity=False,
    format_output=True,
)
results = bing.invoke("Microsoft AutoGen")
print(results)
