A financial services firm needs to extract structured fields such as invoice date, vendor name, and total amount from thousands of PDF invoices. The documents vary in layout across vendors. The firm wants a pretrained model that requires no custom training and can return field-level confidence scores. Which Azure AI Document Intelligence model should they use?
The prebuilt invoice model is trained to extract invoice-specific fields including invoice date, vendor name, and total amount, and it returns confidence scores per field. Because it is pretrained, no custom labeling or training is required, which matches the firm's requirement to process varied vendor layouts quickly.
Why this answer
The firm needs invoice-specific structured fields with confidence scores and no custom training. The prebuilt invoice model in Azure AI Document Intelligence is designed exactly for that, recognizing common invoice fields across varied layouts. General document, custom template, and Read models either lack invoice-specific fields, require training, or return only raw text.
Exam trap
The trap here is choosing a custom model when a pretrained invoice model already covers the required fields without training.
