Integrated vectorization with Azure OpenAI for Azure AI Search now generally available

We're excited to announce the general availability of integrated vectorization with Azure OpenAI embeddings in Azure AI Search. This marks an important milestone in our ongoing mission to streamline and expedite data preparation and index creation for Retrieval-Augmented Generation (RAG) and traditional applications. 

 

Integrated vectorization simplifies RAG pipelines

 

 

Why is vectorization important? 

Vectorization is the process of transforming data into embeddings (vector representations) in order to perform vector search.  Vector search aids in identifying similarities and differences in data, enabling businesses to deliver more accurate and relevant search results. Getting your data prepared for vectorization and indexed also involves various steps, including cracking, enrichment and chunking. The way you perform each of these steps offers opportunities to make your retrieval system more efficient and effective. Take a look at the blog post Outperforming vector search with hybrid retrieval and ranking capabilities that showcases the configurations that would work better depending on the scenario. 

 

What is integrated vectorization? 

Integrated vectorization, a feature of Azure AI Search, streamlines indexing pipelines and RAG workflows from source file to index query. It incorporates data chunking and text/image vector conversions into one flow, enabling vector search across your proprietary data with minimal friction.   

Integration vectorization simplifies the steps required to prepare and process your data for vector retrieval. As part of the indexing pipeline, it handles the splitting of original documents into chunks, automatically creates embeddings with its Azure OpenAI integration, and maps the newly vectorized chunks to an Azure AI Search index. It also enables the automated vectorization of user queries sent to the AI Search index.  

This index can be used as your retrieval system wherever you are building your RAG application, including Azure AI Studio and Azure OpenAI Studio. 

 

What functionality is now generally available? 

The following functionalities within integrated vectorization are generally available as part of REST API version 2024-07-01:  

• Azure OpenAI embedding skill and vectorizer: These features allow for automatic vectorization of text data during data ingestion and query time. 

• Index Projections: This feature enables mapping of one source document associated with multiple chunks, enhancing the relevance of search results. 

• Split skill functionality for chunking with overlap: This functionality divides your data into smaller, manageable chunks for independent processing. 

• Custom Vectorizer functionality: This allows for connection to other embedding endpoints apart from Azure OpenAI. 

• Shared Private Link for Azure OpenAI accounts: This feature, which is part of the latest AI Search management API version 2023-11-01, provides secure and private connectivity from a virtual network to linked Azure services. 

• Customer Managed Keys for indexes with vectorizers: This feature allows for additional security and control over your data through the use of your own keys. When you configure CMK in your AI Search index, your vectorizers operations at query time are also encrypted with your own keys. 

 

How can you get started with integrated vectorization from the Azure portal? 

The Import and vectorize data wizard in the Azure portal simplifies the creation of integrated vectorization components, including document chunking, automatic Azure OpenAI embedding creation, index definition and data mapping. This wizard now supports Azure Data Lake Storage Gen2, in addition to Azure Blob Storage and OneLake (in preview), facilitating data ingestion from diverse data sources. Coming soon, the wizard will also support source document additional metadata mapping to chunks and the Azure portal will provide debug sessions functionality for skillsets configured with index projections.
