### Azure OpenAI[​](#azure-openai "Direct link to Azure OpenAI")

> [Microsoft Azure](https://en.wikipedia.org/wiki/Microsoft_Azure), often referred to as `Azure` is a cloud computing platform run by `Microsoft`, which offers access, management, and development of applications and services through global data centers. It provides a range of capabilities, including software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). `Microsoft Azure` supports many programming languages, tools, and frameworks, including Microsoft-specific and third-party software and systems.

> [Azure OpenAI](https://learn.microsoft.com/en-us/azure/cognitive-services/openai/) is an `Azure` service with powerful language models from `OpenAI` including the `GPT-3`, `Codex` and `Embeddings model` series for content generation, summarization, semantic search, and natural language to code translation.

Set the environment variables to get access to the `Azure OpenAI` service.

Inside an environment variables file (`.env`).

    AZURE_OPENAI_API_KEY="YOUR-API-KEY"AZURE_OPENAI_API_VERSION="YOUR-BASE-URL"AZURE_OPENAI_API_INSTANCE_NAME="YOUR-INSTANCE-NAME"AZURE_OPENAI_API_DEPLOYMENT_NAME="YOUR-DEPLOYMENT-NAME"AZURE_OPENAI_API_EMBEDDINGS_DEPLOYMENT_NAME="YOUR-EMBEDDINGS-NAME"

See a [usage example](/v0.2/docs/integrations/llms/azure).

tip

See [this section for general instructions on installing integration packages](/v0.2/docs/how_to/installation#installing-integration-packages).

*   npm
*   Yarn
*   pnpm

    npm install @langchain/openai

    yarn add @langchain/openai

    pnpm add @langchain/openai

    import { OpenAI } from "@langchain/openai";

Text Embedding Models[​](#text-embedding-models "Direct link to Text Embedding Models")
---------------------------------------------------------------------------------------

### Azure OpenAI[​](#azure-openai-1 "Direct link to Azure OpenAI")

See a [usage example](/v0.2/docs/integrations/text_embedding/azure_openai)

    import { OpenAIEmbeddings } from "@langchain/openai";

    const embeddings = new OpenAIEmbeddings({  azureOpenAIApiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.AZURE_OPENAI_API_KEY  azureOpenAIApiVersion: "YOUR-API-VERSION", // In Node.js defaults to process.env.AZURE_OPENAI_API_VERSION  azureOpenAIApiInstanceName: "{MY_INSTANCE_NAME}", // In Node.js defaults to process.env.AZURE_OPENAI_API_INSTANCE_NAME  azureOpenAIApiDeploymentName: "{DEPLOYMENT_NAME}", // In Node.js defaults to process.env.AZURE_OPENAI_API_EMBEDDINGS_DEPLOYMENT_NAME});

Chat Models[​](#chat-models "Direct link to Chat Models")
---------------------------------------------------------

### Azure OpenAI[​](#azure-openai-2 "Direct link to Azure OpenAI")

See a [usage example](/v0.2/docs/integrations/chat/azure)

    import { ChatOpenAI } from "@langchain/openai";

    const model = new ChatOpenAI({  temperature: 0.9,  azureOpenAIApiKey: "SOME_SECRET_VALUE", // In Node.js defaults to process.env.AZURE_OPENAI_API_KEY  azureOpenAIApiVersion: "YOUR-API-VERSION", // In Node.js defaults to process.env.AZURE_OPENAI_API_VERSION  azureOpenAIApiInstanceName: "{MY_INSTANCE_NAME}", // In Node.js defaults to process.env.AZURE_OPENAI_API_INSTANCE_NAME  azureOpenAIApiDeploymentName: "{DEPLOYMENT_NAME}", // In Node.js defaults to process.env.AZURE_OPENAI_API_DEPLOYMENT_NAME});

Document loaders[​](#document-loaders "Direct link to Document loaders")
------------------------------------------------------------------------

### Azure Blob Storage[​](#azure-blob-storage "Direct link to Azure Blob Storage")

> [Azure Blob Storage](https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blobs-introduction) is Microsoft's object storage solution for the cloud. Blob Storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that doesn't adhere to a particular data model or definition, such as text or binary data.

> [Azure Files](https://learn.microsoft.com/en-us/azure/storage/files/storage-files-introduction) offers fully managed file shares in the cloud that are accessible via the industry standard Server Message Block (`SMB`) protocol, Network File System (`NFS`) protocol, and `Azure Files REST API`. `Azure Files` are based on the `Azure Blob Storage`.

`Azure Blob Storage` is designed for:

*   Serving images or documents directly to a browser.
*   Storing files for distributed access.
*   Streaming video and audio.
*   Writing to log files.
*   Storing data for backup and restore, disaster recovery, and archiving.
*   Storing data for analysis by an on-premises or Azure-hosted service.

*   npm
*   Yarn
*   pnpm

    npm install @azure/storage-blob

    yarn add @azure/storage-blob

    pnpm add @azure/storage-blob

See a [usage example for the Azure Blob Storage](/v0.2/docs/integrations/document_loaders/web_loaders/azure_blob_storage_container).

    import { AzureBlobStorageContainerLoader } from "langchain/document_loaders/web/azure_blob_storage_container";

See a [usage example for the Azure Files](/v0.2/docs/integrations/document_loaders/web_loaders/azure_blob_storage_file).

    import { AzureBlobStorageFileLoader } from "langchain/document_loaders/web/azure_blob_storage_file";
