Document AI is introducing document-level prompting for custom document processors. This feature allows you to provide an overall description of the document to inject deep business knowledge into the model, leading to improved extraction quality.

Document-level prompting offers improved accuracy by giving the model necessary context for extraction at the document level. This allows for easily supplied general information, such as geographical limitations (for example, all the address fields are located in the USA), to guide the model.

For more details, refer to the documentation on custom extractor mechanisms and document-level prompting.

A monitoring dashboard web interface is available in Preview to monitor at the project and processor level.

You can monitor a number of metrics, such as number of successfully processed pages and sync processing latency, across fields like location, processor_type, and processor_id over time.

For more information, see monitoring dashboard.

Automated schema extraction for custom extractor processors is in Preview.

This feature allows you to automatically extract a document schema from a test document you supply. Then, you can approve or decline the schema and edit it manually. This saves time and effort when defining the document schema for your custom processor and allows you to focus on refining the schema.

When creating a custom extractor processor, find the Generate from document option in the Get started tab of the Google Cloud console.

Gemini layout parser is in Preview. The Gemini layout parser gives better layout quality on table recognition, reading order and text recognition on PDF files. You can enable the feature by default by selecting layout parser processor version pretrained-layout-parser-v1.4-2024-08-25, pretrained-layout-parser-v1.5-2025-08-25 or pretrained-layout-parser-v1.5-pro-2025-08-25 for your processor.

Layout parser support for DOCX, PPTX, XLSX, and XLSM file types in Document AI is in General Availability (GA). It makes content like paragraphs, tables, lists, and structural elements like headings, page headers, and footers easily accessible. It also creates context-aware chunks that facilitate information retrieval in a range of generative AI and discovery applications.

For more information, see Process documents with Layout Parser.

Custom splitter model pretrained-splitter-v1.5-2025-07-14 with zero-shot splitting, classification and confidence scores is available as Release Candidate (Preview).

To avoid service disruptions, migrate to a later version such as pretrained-foundation-model-v1.5-2025-05-05 or pretrained-foundation-model-v1.5-pro-2025-06-20. To learn more about the migration process, refer to Manage processor versions.

Document AI supports two service tiers and associated quotas: provisioned and best effort tiers.

The base is the provisioned tier quota, which provides 120 pages per minute for Gemini 2.0 and 2.5 Flash LLM and 30 pages per minute for Gemini 2.5 Pro LLM.

If you require more volume, best effort tier quota provides 120 pages per minute for Gemini 2.0 2.5 Flash and 60 pages per minute for Gemini 2.5 Pro. It's only used when the provisioned quota has been exhausted. This applies to the BestEffortOnlineProcessDocumentPagesPerMinutePerProjectUS and EU quotas and, in the console, best_effort_online_process_document_pages_us and eu.

Best effort can get up to 240 pages per minute for custom data extractor models v1.4 and v1.5 with a quota increase request (QIR). You can make a QIR by contacting your sales team representative.

There is no service level agreement (SLA) for best effort tier.

Custom extractor model pretrained-foundation-model-v1.5-pro-2025-06-20 is available as General Availability (GA).

For more information about available models, see the custom extractor page.

Derived entity and signature detection are now supported in custom extractor models pretrained-foundation-model-v1.4-2025-02-05 as General Availability (GA) and in pretrained-foundation-model-v1.5-2025-05-05, as well as pretrained-foundation-model-v1.5-pro-2025-06-20 as Preview.

Signature detection lets you identify handwritten signatures by using visual cues in the document. Derived entity detection lets you deduce entities by inference without requiring the value to be explicitly present in the text. You can use this feature to deduce the country in an address, counting items in a table, or detecting if an ID is fake.

These can be enabled in the console when creating labels or by using the DocumentSchema.EntityType resource in the API.

For more information, read Custom extractor with derived fields and choose label attributes.

Custom extractor model pretrained-foundation-model-v1.5-pro-2025-06-20 powered by Gemini 2.5 Pro is in Preview. It has ML processing available for US and EU regions, a maximum page limit of 30 pages, and processing requests of 30 pages per minute.

For more information, see Managing processor versions.

Document AI VPC service controls (VPC-SC) integration now supports identity groups.

For more information on setting up VPC-SC identity groups, read Configure identity groups and third-party identities in ingress and egress rules.

Document AI now supports Identity and Access Management (IAM) deny policies. These policies allow you to define deny rules that prevent certain principals from using certain permissions to access Google Cloud resources, regardless of the roles they're granted.

For more information, read Deny policy overview and Document AI security and compliance.

The Document AI CDE processor now supports merging the child entities of nested entities that extend across several pages. This is supported in custom extractor model pretrained-foundation-model-v1.5-2025-05-05.

This change is automatic in all processors.

For customers with existing v1.5 processors, to make use of this feature, you must relabel the nested entities in different pages.

To learn more about the labeling process, refer to Label documents.

Custom Extractor model pretrained-foundation-model-v1.5-2025-05-05 is in General Availability (GA) and has fine-tuning available for the US and EU.

From version v1.4 and later, we will use a new quota for online processing called Number of online process document pages per minute per processor type and model version. This quota will be enforced at a per-page and per-foundation model level. There will be no change to the batch processing quota.

These can be enabled in the console when creating labels and by using the DocumentSchema.EntityType.

For more information, read Managing processor versions.

We've increased the maximum file size for online processing requests from 20 MB to 40 MB. This applies to all types of processors.

For more information, see the Document AI limits page.

Cross-regions importing of fine-tuned models is now supported for processor versions based on Gemini 1.5 and later, such as custom extractors pretrained-foundation-model-v1.2-2024-05-10 and later.

For more information, see Managing processor versions.

Custom extractor model pretrained-foundation-model-v1.5-2025-04-25 powered by Gemini 2.5 Flash LLM is available as Public Preview in US regions. The custom extractor model supports a quota of up to 15 pages per minute for online process requests.

For more information about available models, see Custom extractor model versions.

Previous Custom Extractor versions pretrained-foundation-model-v1.0-2023-08-22 and pretrained-foundation-model-v1.1-2024-03-12 will be deprecated on April 9, 2025. To ensure uninterrupted service, prediction traffic to these versions, including any fine-tuned variants, will be automatically redirected to the latest version, pretrained-foundation-model-v1.4-2025-02-05.

For guidance on how to fine-tune a new version, refer to the fine tuning documentation.

All processors can now extend the Maximum page limit for online and synchronous requests up to 30 pages.
