计量和收费逻辑（Flex 计划）

在使用 UiPath™ Document Understanding^TM 新式项目时，了解 AI Unit 的消耗情况至关重要。

AI Unit 每页费用

对于 Document Understanding 新式项目，无论在运行时对页面执行何种操作，或者是否使用多个新式项目从同一页面提取数据，都只需对一个 AI 单元收费。这包括数字化操作（例如 OCR）以及提取或分类操作。这适用于所有操作，包括机器人流程自动化 (RPA) 和 API 操作。

AI Unit 和模型训练

训练和提供模型时，不会对 AI Unit 收费。这意味着您可以随意训练模型以提高性能、开发新功能和进行试验，而无需担心会产生额外的 AI Unit 费用。

生成式功能

Depending on the version of the activity package you are using, there are slight differences related to AI units consumption. The consumption models are detailed in the sections that follow.

Activities version 24.12-preview and newer

This consumption is applied when using PredefinedGenerative projects with the following::

IntelligentOCR newer than 6.23.2-preview.
DocumentUnderstanding.Activities newer than 2.13.2-preview.
Document Understanding API v1.1.

Consumption:

1 AI Unit per processed page (includes Generative Classification and Generative Extraction)

Note: When enabled, Generative Validation adds 1 AI Unit, bringing the total consumption to 2 AI Units per processed page.

Activities version older than 24.12-preview

This consumption model is applied when using:

IntelligentOCR up to 6.23.2-preview with PredefinedGenerative projects;
DocumentUnderstanding.Activities up to 2.13.2-preview with PredefinedGenerative projects;
Document Understanding API v1.0 with Predefined projects.

AI Units consumption for generative features in activity versions older than 24.12-preview is detailed in the following table.

生成式功能	已使用的 AI Unit
生成分类器	每次操作 0.2 个
生成式提取	每次操作 1.2 个
生成式验证	每次操作 1 个

For example, if you process a document using extraction and Generative Classifier, the consumption is 1.2 AI units per page.

Document Understanding 活动包

For the DocumentUnderstanding.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 pre-defined generative or 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.

For the InteligentOCR.Activities package, one AI unit is charged per page, 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.
