Known limitations

This page provides an overview of the current specifications and parameters for optimal utilization of Document UnderstandingTM modern projects.

Project-based limits​

Description Limit
Supported file formats
  • PNG
  • JPG/JPEG
  • PDF
  • TIF/TIFF
Image size limits
  • Minimum: 50 x 50 pixels
  • Maximum: 10,000 x 10,000 pixels
Maximum number of pages in a document type 5000

After a certain point, adding more data doesn't improve model performance. This limitation makes sure that you do not annotate more documents than needed.

Maximum number of pages in a document 500 for previous generation models, 100 for Helix Extractor models
Maximum number of pages in a project 30,000
Maximum number of pages per document for pre-labeling 20

If a documents has more than 20 pages, only the first 20 pages are pre-annotated.

Maximum number of fields 300
Maximum number of requests processed in parallel 10
Maximum number of pages for out-of-the-box model processing 20
Maximum file size for digitization 160 MB
Maximum pages per document for digitization 500 pages
Number of characters for the classification name
  • Minimum: 1
  • Maximum: 50
Number of characters for the classification description
  • Minimum: 0
  • Maximum: 2000
Number of characters in a document for classification
  • Minimum: 0
  • Maximum: 1e10 (virtually unlimited)
Number of of classifiers
  • Minimum: 1
  • Maximum: 50

Activity or API-based limits​

Description Limit
Supported file formats

  • TIF/TIFF
Image size limits
  • Minimum: 50 x 50 pixels
  • Maximum: 10,000 x 10,000 pixels
Maximum file size for digitization 160 MB
Maximum number of requests processed in parallel (a project version deployed in a modern project) 10
Maximum number of pages for out-of-the-box model processing 20 pages

Current limitations when migrating existing AI Center-based projects​

  • Currently, importing datasets larger than 3000 pages is not supported. Only the initial 3000 pages will be successfully imported, with any additional pages failing to do so. For example, if your dataset consists of 2999 pages and you try to import a document of 4 pages, the process will not succeed.
  • Batch names and corresponding batch results are not currently available. If your data is organized into batches, this information is not displayed yet, but it is saved.
  • Exports from AI Center are not supported. Only exports from Document Manager are supported.
