The new Azure AI Translator API provides you with flexibility to choose general neural machine translation (NMT), or a list of generative AI large language models (LLMs) at a request level. During preview the API supports general NMT, gpt-4o and gpt-4o-mini models. Using generative AI models, the new API offers new capabilities to produce tone translation, gender translation, and adaptive custom translation. Languages supported are listed here.
This .NET web app (ASP.NET Core 8) lets users enter text, select a target language, and add optional inputs. After clicking ‘Translate’, it uses the Azure AI Translator API (2025-05-01-preview) to return the translated text, charges, and response time on the UI.
Set your Azure Translator resource details in appsettings.json or via environment variables:
- AzureTranslator:Endpoint (e.g.,
https://<your-resource-name>.cognitiveservices.azure.com) - AzureTranslator:Key
- AzureTranslator:Region
- AzureTranslator:ApiVersion (defaults to
2025-05-01-preview)
Environment variable examples (Windows PowerShell):
$env:AzureTranslator__Endpoint = 'https://<your>.cognitiveservices.azure.com'
$env:AzureTranslator__Key = '<your-key>'
$env:AzureTranslator__Region = '<your-region>'
$env:AzureTranslator__ApiVersion = '2025-05-01-preview'# from the project folder
