Guia do usuário do Document Understanding.

Última atualização 29 de abr de 2026

Lógica de medição e cobrança (Plano Flex)

Ao usar projetos modernos do UiPath® Document UnderstandingTM , é essencial entender o consumo de unidades de IA.

Dica:

How charging works for modern projects

For Document Understanding modern projects, only one single AI unit is charged per page, regardless of the operations performed at runtime or the number of modern projects extracting data from the same page. The single per-page charge covers:

  • Digitization, including OCR
  • Extração
  • Classificação

This applies to both robotic process automation (RPA) and REST API operations. For full REST API pricing — including how classic-project API calls are charged — see Metering and Charging in the API guide.

Through Document Understanding activity packages

For both DocumentUnderstanding.Activities and IntelligentOCR.Activities, one AI unit is charged per page, regardless of the operations performed (digitization, extraction, or classification).

The one AI unit per-page rule applies only when:

  • For DocumentUnderstanding.Activities: a pre-defined generative or modern project classifier or extractor is in use.
  • For IntelligentOCR.Activities: a modern project classifier or extractor is in use.

If you use any other classifier or extractor, the respective consumption logic from classic projects is added to the one AI unit per page. For more information, see Mixed projects.

Generative features — Activities 24.12-preview and above

This consumption applies in the following situations:

  • Usando atividades versão 24.12-preview e posterior com projetos PredefinedGenerative .
  • Usando a API Document Understanding v1.1 com projetos PredefinedGenerative .

There are no additional AI units consumed when using Generative Classification and Generative Extraction. Only one single AI unit is charged per page, regardless of the operations performed, including Generative Classification and Generative Extraction.

Observação:

Using Generative Validation consumes an additional one AI unit for each processed page. This brings the total to two AI units consumed per page when generative validation runs.

Generative features — Activities up to 24.12-preview

This consumption applies in the following situations:

  • Usando a versão de atividades até 24.12-prévia com o projeto Predefined.
  • Usando a API do Document Understanding v1.0 com o projetoPredefined.

In these versions, generative features incur specific charges per operation, as described in the following table.

Table 1. Generative features AI units consumption for activities versions up to 24.12-preview

Recurso gerativoAI Units Consumidas
Classificador Generativo0,2 por operação
Extração generativa1,2 por operação
Validação generativa1 por operação

Treinamento do modelo

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

Mixed projects (modern + classic)

When a project uses both classic and modern experiences, both pricing models apply based on their respective consumption.

The pricing model for classic projects applies in the following circumstances:

  • Extraction and classification done using classic projects, regardless of the activity package used (IntelligentOCR or DocumentUnderstanding.Activities).
  • Extraction and classification done using the out-of-the-box models included with the pre-defined project, regardless of the activity package used.
  • REST API calls against classic-project models — classic per-capability rates apply, not the 1 AI unit per-page rule.

For full classic-project metering — including activity-based rates per OCR engine, classifier, and extractor — see the Document Understanding User Guide for Classic Experience. For classic-project REST API rates specifically, see Metering and Charging in the API guide.
