Google Document AI Custom Extractor 3.5

Google Cloud's Gemini-powered Document AI processor for extracting the exact fields and derived values defined in a business schema.

Plain-English overview

What Google Document AI Custom Extractor 3.5 actually is

Custom Extractor 3.5 is for jobs where plain OCR is not enough. A team defines fields such as supplier, renewal date, line items, or risk clauses, and the processor returns those named entities from documents with variable layouts.

The Gemini 3.5 Flash version can also populate nested or derived information, such as calculating a value or inferring a category from the document. That makes it closer to configurable intelligent document processing than a generic vision model.

Good fit for

  • Contracts, invoices, statements, and business forms
  • Schema-driven fields across changing layouts
  • Derived values that are not copied verbatim from one spot

Data and training

The route matters.

Google says Document AI customer documents and predictions are not used to train its models. Online documents are processed in memory without disk persistence; batch inputs have a failsafe retention of up to one day.

This is a concise reading of the cited provider material, not legal advice. A third-party gateway can have different storage, routing, training, and residency terms from the model maker's direct API.
