Class AzureOpenAiChatModel

java.lang.Object

dev.langchain4j.model.azure.AzureOpenAiChatModel

All Implemented Interfaces:

dev.langchain4j.model.chat.ChatLanguageModel, dev.langchain4j.model.chat.TokenCountEstimator

public class AzureOpenAiChatModel
extends Object
implements dev.langchain4j.model.chat.ChatLanguageModel, dev.langchain4j.model.chat.TokenCountEstimator

Represents an OpenAI language model, hosted on Azure, that has a chat completion interface, such as gpt-3.5-turbo.

Mandatory parameters for initialization are: baseUrl, apiVersion and apiKey.

There are two primary authentication methods to access Azure OpenAI:

1. API Key Authentication: For this type of authentication, HTTP requests must include the API Key in the "api-key" HTTP header.

2. Azure Active Directory Authentication: For this type of authentication, HTTP requests must include the authentication/access token in the "Authorization" HTTP header.

More information

Please note, that currently, only API Key authentication is supported by this class, second authentication option will be supported later.
