Azure OpenAI Embeddings Langchain is an exciting technology that allows you to integrate OpenAI models with Azure services.

It uses a technique called embeddings to represent text, images, and other data in a numerical format that can be easily processed by machines.

This enables seamless interaction between OpenAI models and other Azure services, such as Azure Cognitive Search and Azure Kubernetes Service.

These services can be used to build custom applications that leverage the power of OpenAI models.

The Langchain is a key component of Azure OpenAI Embeddings, allowing you to create a knowledge graph that can be queried and updated in real-time.

By using Langchain, you can build applications that can reason and make decisions based on the knowledge graph.

A unique perspective: Azure Openai Embeddings

Azure OpenAI Embeddings

Azure OpenAI Embeddings allow you to access Azure OpenAI embedding models by creating an Azure account, getting an API key, and installing the langchain-openai integration package.

You'll need to have an Azure OpenAI instance deployed, which you can do by following the guide on the Azure Portal. Once you have your instance running, make sure you have the name of your instance and key, which you can find in the Azure Portal under the "Keys and Endpoint" section of your instance.

To use Azure OpenAI Embeddings, you'll need to specify the number of dimensions for the embeddings, which can be specified only if the underlying model supports it. You can also specify the timeout for requests to the OpenAI completion API, which can be a float, httpx.Timeout, or None.

Here are the parameters you can use with AzureOpenAIEmbeddings:

  • texts (List[str]) - The list of texts to embed.
  • chunk_size (int | None) - The chunk size of embeddings. If None, will use the chunk size specified by the class.

These parameters will give you a list of embeddings, one for each text, in the format List[List[float]].

Prerequisites

To get started with Azure OpenAI Embeddings, you'll need to fulfill a few prerequisites. First and foremost, you'll need an Azure subscription, which you can create for free.

An Azure OpenAI resource with the text-embedding-ada-002 (Version 2) model deployed is also required. This model is currently only available in certain regions, so you may need to check the Azure Portal for availability.

You'll also need Python 3.8 or later version installed on your machine. Furthermore, you'll need to install the following Python libraries: openai, num2words, matplotlib, plotly, scipy, scikit-learn, pandas, and tiktoken.

To work with Azure OpenAI Embeddings, it's recommended to use Jupyter Notebooks.

Next Steps

Now that you've generated Azure OpenAI embeddings, it's time to take your project to the next level. You've got a wealth of information at your fingertips, and it's time to put it to use.

You can store your embeddings and perform vector similarity searches using your choice of Azure service. This is a powerful way to unlock the potential of your embeddings.

To get started, consider the following options:

  • Store your embeddings and perform vector (similarity) search using your choice of Azure service:

This is a great way to take your project to the next level and unlock the full potential of Azure OpenAI embeddings.

Langchain Openai Embeddings

To access Azure OpenAI embedding models, you'll need to create an Azure account, get an API key, and install the langchain-openai integration package. This integration package can be installed using pip.

You'll need to have an Azure OpenAI instance deployed, which can be done by following the guide on the Azure Portal. Once you have your instance running, make sure you have the name of your instance and key, which can be found in the Azure Portal under the "Keys and Endpoint" section of your instance.

The number of dimensions for the embeddings can be specified if the underlying model supports it. If not provided, it will be automatically inferred from the env var AZURE_OPENAI_ENDPOINT.

Here are the parameters that can be specified when using the AzureOpenAIEmbeddings class:

  • texts (List[str]): The list of texts to embed.
  • chunk_size (int | None): The chunk size of embeddings. If None, will use the chunk size specified by the class.

Here is an example of how to use the AzureOpenAIEmbeddings class to embed a list of texts:

  • texts = ["text1", "text2", "text3"]
  • chunk_size = None
  • azure_openai_embeddings = AzureOpenAIEmbeddings(texts=texts, chunk_size=chunk_size)
  • embeddings = azure_openai_embeddings.embed()

The embeddings will be returned as a list of lists of floats, one for each text.
