Google Document AI

Google Document AI can process a broad range of document types, including general forms, invoices, receipts, contracts, identity documents, tax forms such as W-2s, bank statements, and pay stubs. Specialized processors are available for many of these categories, and a general-purpose OCR processor handles documents that do not fit a specific type.

The metadata for this model does not specify a context window or token limit. Google Document AI is a document extraction service rather than a generative language model, so its constraints are defined by document size and page count limits per API request rather than a token context window. Refer to the Google Cloud documentation for current per-request page limits.

Pricing information is not included in the available metadata. Google Document AI is a Google Cloud service billed based on the number of pages processed and the processor type used. Current pricing details are available on the Google Cloud Document AI pricing page.

No training is required to use the pre-built processors. Google Document AI also offers a Custom Document Extractor that allows users to train a processor on their own labeled documents when the pre-built processors do not meet their needs.

The API returns results as structured JSON objects containing extracted text, field names and values, confidence scores, and bounding box coordinates for each detected element. This makes the output directly usable in downstream data pipelines without additional parsing.
