Quick take
Google Cloud's Gemini-assisted parser for preserving document hierarchy and creating context-rich chunks for enterprise search and RAG.
Version 1.6 is a release candidate and uses a global Gemini endpoint. Google explicitly says it does not satisfy its normal data-residency standard, even when the request enters through a US or EU location.
Google Cloud's Gemini-powered Document AI processor for extracting the exact fields and derived values defined in a business schema.
This version is a preview and does not support fine-tuning. Define an evaluation set and human-review rules before trusting extracted fields in legal, financial, or operational workflows.
