Azure OpenAI​

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 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.

  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​

Azure OpenAI​

See a usage example

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
});

Azure Blob Storage​

Azure Blob Storage 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 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 install @azure/storage-blob

See a usage example for the Azure Blob Storage.

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

See a usage example for the Azure Files.

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