Limitations for Document AI
Document AI has the current limitations.
Criteria
Stable release July 2023
Dataset
- Maximum of 30,000 documents total
- Maximum of 250,000 pages total
Document import
- Maximum of 5,000 documents per import
- Maximum of 200 pages per document
Limits to train a Custom Document Extractor (CDE)
Model-based training (GA)
Template-based training (GA)
- Training dataset maximums: 25,000 documents; 100,000 pages
- Training dataset minimum: each label needs to be present on at least 1 label per 10 documents
- Test dataset maximums: 2,000 documents; 8,000 pages
- Test dataset minimum: every label on at least 10 documents
- Maximum of 200 pages per document
Template-based training (GA)
- Training dataset maximums: 300 documents, 300 pages
- Training dataset minimum: every label on at least on at least 3 documents
- Test dataset maximums: 2,000 documents; 8,000 pages
- Test dataset minimum: every label on at least 3 documents
- Maximum of 20 pages per document
Limits to train a Custom Document Classifier (CDC) or a Custom Document Splitter (CDS)
- Training dataset maximums: 30,000 documents; 100,000 pages
- Training dataset minimum: every label on at least 10 documents
- Test dataset maximums: 2,000 documents; 8,000 pages
- Test dataset minimum: every label on at least 2 documents
- Maximum of 200 pages per document
Labeling
- To get started, verify document labels meet defined minimum training and evaluation thresholds.
- To begin evaluating model performance for documents with layout variation, label at least 100 documents. Specifically, verify that each label exists on 50 documents in training and 50 in evaluation.
- Maximum allowed labels (fields): 150
- Label size limits (characters): Long items aren't well supported, but there's no explicit limit. Chunk documents into 800- or 1,000-token pieces, with 100 to 200 tokens overlapping between chunks. (Items longer than the overlapping area might run into quality issues.)
- Label occurrences in a document: No limit
Geographic coverage
- Regions generally supported: US, EU (multiregion)
- Regions with limited accessibility: Germany, Singapore, UK, Canada, India, Australia
