Metering and charging logic

This section includes specific information about the metering & charging logic for AI units, depending on the used activity, and explains the AI unit cost per page for extractors, OCR engines, classifiers, and other components. More details about AI Units can be found here and details about licensing can be found here.

Tip:
Note: The charges apply per extracted page and per extraction method, meaning that, for example, both Form Extractor and Machine Learning Extractor are run, then the charges would be 1.2 AI units.
Note: For training costs, check the AI units page from the AI Center guide.

Generative features

Depending on the version of the activity package you are using, there are slight differences related to AI units consumption:
  • Activities versions newer than:
    • IntelligentOCR 6.23.2-preview
    • DocumentUnderstanding.Activities 2.13.2-preview
  • Activities versions up to:
    • IntelligentOCR 6.23.2-preview
    • DocumentUnderstanding.Activities 2.13.2-preview

Generative prelabeling does not consume AI Units when using public endpoints or skills deployed in Automation Cloud™ from Document Manager sessions hosted on Automation Cloud. Generative prelabeling consumes AI Units when calling a public endpoint from a session hosted on Automation Suite, or when calling a skill deployed in Automation Suite from a Document Manager session hosted on Automation Cloud.

Activities version 24.12-preview and above

This consumption is applicable in the following situations:
  • Using the following activities versions with PredefinedGenerative projects:
    • IntelligentOCR newer than 6.23.2-preview
    • DocumentUnderstanding.Activities newer than 2.13.2-preview
  • Using Document Understanding API v1.1 with PredefinedGenerative projects.

There are no additional AI units consumed when using Generative Classification and Generative Extraction. There is only one single AI unit is charged, regardless of the operations performed on a page at runtime, including Generative Classification and Generative Extraction.

Note: Using Generative Validation consumes an additional one AI unit for each processed page. This brings the total of two AI units consumed for processed pages using generative validation.

Activities version up to 24.12-preview

This consumption is applicable in the following situations:
  • Using the following activities versions with PredefinedGenerative projects:
    • IntelligentOCR up to 6.23.2-preview
    • DocumentUnderstanding.Activities up to 2.13.2-preview
  • Using Document Understanding API v1.0 with the Predefined project.

Using generative features incur specific charges for each operation, as described in the following table.

Generative Classifier0.2 per operation
Generative Extraction1.2 per operation
