Overview

Concrete tool for creating an Azure-specific Mistral API client provided by the mistralai_azure package.

Description

The MistralAzure class initializes a client for Mistral models deployed on Azure AI. It accepts azure_api_key (string or callable) and azure_endpoint (the Azure deployment URL). The constructor normalizes the endpoint by stripping trailing slashes and appending /v1/ if not already present. It registers a CustomUserAgentHook that rewrites the User-Agent header to identify Azure SDK traffic. The client exposes lazy-loaded .chat and .ocr sub-SDKs.

Usage

Install mistralai_azure and instantiate with Azure credentials obtained from the Azure portal after deploying a Mistral model.
