Metering and charging logic (Flex Plan)

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.

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.
