  • 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 that 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, regardless of 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 rerun the same set.
    3. Translation: You are charged for every character of text translated by your Custom Translation model.
  • The S1-S4 tiers are designed to provide discounts for users who require high volumes of Standard Translation – not Custom – every month. While a discount is offered on the Standard Translation rate, S1-S4 tiers do not include a discount on Custom Translation. The C2-C4 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 rate, C2-C4 tiers do not include a discount on Standard Translation.

  • In order to receive volume discounts on both Standard and Custom Translation, you are required to allocate both an S1-S4 instance AND a C2-C4 instance, directing Standard Translation to the S instance and Custom Translation to the C instance.
