Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month fall on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the upcoming month. Sign in to the Azure pricing calculator to see pricing based on your current program/offer with Microsoft. Contact an Azure sales specialist for more information on pricing or to request a price quote. See frequently asked questions about Azure pricing.

  • Standard Translation is an easy one-step process, in which you provide an input sentence and Azure's pre-trained models translate them into a target language. By contrast, Custom Translation is a two-step process, in which first you train your own models using training data you upload to the translation service. Once your model has been trained, you can perform the translation as you would with Standard Translation.

  • There are three billed activities that you can perform during Custom Translation:

    1. Model hosting: Hosting a model means that it is available to use for Custom Translation. You are charged a flat fee for every model that is hosted during a billing period. This is NOT pro-rated if the model is hosted for less than the full month.
    2. Training: Every time you train a model, you are charged a fee for every character in the training data. You are charged for characters in both the source and target languages of the training set, but there is a cap to how much you can be charged for any given training run, no matter how many characters are in your training data. This cap applies to each training run, i.e. you would be charged if you were to re-run the same set.
    3. Translation: You are charged for every character of text translated by your Custom Translation model.
  • The S1 instance’s commitment tiers are designed to provide discounts for users who require high volumes of Standard Translation (not Custom Translation) every month. While a discount is offered on the Standard Translation rates, the S1 instance’s commitment tiers do not include discounts on Custom Translation.

    The C2-C4 instance tiers are intended to provide discounts to customers who regularly perform high volumes of Custom Translation. While a discount is offered on the Custom Translation rates, C2-C4 tiers do not include discounts on Standard Translation.

  • In order to receive discounts on both Standard and Custom Translation, you will need to allocate an S1 instance with a specified commitment tier AND a separate C2-C4 instance, directing Standard Translation to the S1 instance and Custom Translation to the C2-C4 instance.

  • Azure AI Translator is a non-regional resource and will be available regardless of the region where you create the resource.
