Metering and charging logic

When using UiPath® Document Understanding^TM modern projects, it's essential to understand the consumption of AI units. Modern projects use one AI unit per page, regardless of the processing form (digitization, classification, extraction, and any combination of these on the same document).

AI units charges per page

A unique feature for modern projects is that regardless of the operations performed on a page at runtime - be it digitization, extraction, or classification - only one single AI unit is charged. This applies to all operations, encompassing both robotic process automation (RPA) and API operations.

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.

This feature is currently part of an audit process and is not to be considered part of the FedRAMP Authorization until the review is finalized. See here the full list of features currently under review.

Check the examples below for AI units consumption depending on the operations done per page:

• OCR only → 1 AI unit / page
• OCR and classification → 1 AI unit / page
• OCR, classification, and extraction → 1 AI unit / page
• OCR, classification, extraction, and Generative Validation → 2 AI units / page

Document Understanding activity packages

For the DocumentUnderstanding.Activities package, the following metering and charging policies apply:

• If you use the Classify Document activity to process a document, triggering digitization and the result is stored in a Document Data → 1 AI unit / input page
• If you then use the Extract Document Data activity to:
  • Process a document using the file itself as input, triggering digitization → the total cost is 2 AI units / page
    Note: You can also process a document using the file itself with the Extract Document Data activity without classifying it previously. In this case, the total cost is 1 AI unit / page.
  • Process a document using Document Data, the output of Classify Document, as input → the total cost is 1 AI Unit / page

For the InteligentOCR.Activities package, one AI unit is charged per page, regardless of the operations performed - whether it's digitization, extraction, or classification. This only applies when a modern project classifier or extractor is in use. If you use any other classifier or extractor, the respective consumption logic from the classic projects is added to the one AI unit per page.

AI units and model training

There are no AI units charged when training and serving models. This means you can freely train models to improve performance, develop new capabilities, and experiment without concerns about incurring additional AI units charges.
