Integrating Azure OpenAI Embeddings with LangChain
In the fast-paced world of AI, managing and accessing data through efficient means is vital. With the advancements in language models, integrating services like Azure OpenAI with powerful frameworks like LangChain creates a robust solution for developers aiming to build applications that leverage these technologies. This blog post will guide you through integrating Azure OpenAI Embeddings with LangChain, enabling you to harness the power of AI for your applications.
What are Azure OpenAI Embeddings?
Azure OpenAI service provides REST API access to OpenAI's powerful language models—including GPT-4 and embeddings models that transform text into mathematical representations. These embeddings allow applications to perform semantic searches and comparisons between texts.
Embeddings are effectively captured representations of semantic meaning, allowing algorithms to analyze text at a deeper level. For instance, similar texts will have vector representations that are close together in a high-dimensional space, enabling more meaningful comparisons than a mere keyword match.
But why utilize Azure OpenAI? Here are a few advantages:
Integration Advantage: Easily integrates with a full suite of Azure cloud services.
Security & Reliability: Inherits top-notch security capabilities from the Azure platform.
Scalability: Applications are easy to scale as demands evolve.
Ease of Use: Azure provides user-friendly tools, allowing developers to focus on building applications rather than managing infrastructure.
Introducing LangChain
LangChain is an open-source framework designed to streamline the development of applications powered by Large Language Models (LLMs). It facilitates various tasks, such as prompting, output parsing, and even building agents that can perform complex actions in response to user input. Essentially, LangChain simplifies the integration of LLMs into practical applications, making it easier to create AI-powered solutions.
Key functionalities include:
Combining LLMs with External Data: Easily works with documents, databases, and other relevant data sources to enrich output content.
Transforming Data into Vectors: Efficiently prepares data for searching and retrieval.
Actions on Retrieved Data: Processes can be defined to perform actions based on the retrieved information, such as sending emails or generating reports.
Getting Started with the Integration
To effectively integrate Azure OpenAI Embeddings with LangChain, you need a few things:
An Azure subscription with the Azure OpenAI service deployed.
Access to the Python programming environment, preferably with installation managed through tools like Anaconda or pip.
Relevant packages:
1
openai
,
1
langchain
, and any additional libraries you may find necessary for your application.
Set Up Azure OpenAI Resource: Follow this guide to create an OpenAI resource in Azure. Deploy the necessary model, preferably the text-embedding-ada-002 model.
Install Required Packages: Run the following command:
1
2
bash
pip install openai langchain
Set Up Environment Variables: You'll want to set up your environment with the necessary authentication tokens.
1
2
3
4
5
documents = [
'This is an example document.',
'Here is another document text.'
]
document_embeddings = embeddings.embed_documents(documents)
For Queries:
1
2
query = 'What is the purpose of Azure OpenAI?'
query_embedding = embeddings.embed_query(query)
Step 4: Storing & Retrieving Data
Embedding your documents allows for efficient searching. You can store these embeddings in a vector database like Azure Cosmos DB and leverage vector searches to retrieve the most relevant documents in response to queries.
Step 5: Performing Search Using Cosine Similarity
To find documents that are semantically similar to the query, you can calculate cosine similarity between the document embeddings and the query embedding. This is achievable through straightforward numpy operations:
```python
import numpy as np
def cosine_similarity(a, b):
return np.dot(a, b) / (np.linalg.norm(a) * np.linalg.norm(b))
Assuming document_embeddings contain your embeddings
results = []
for embedding in document_embeddings:
similarity = cosine_similarity(query_embedding, embedding)
results.append(similarity)
```
You can then rank results based on similarity scores, providing more relevant options based on user input.
