Document AI release notes

Custom extractor model pretrained-foundation-model-v3.5-2026-05-26 powered by Gemini 3.5 Flash LLM is available in Preview.

This processor version has ML processing capabilities in the US and EU.

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

Custom extractor offers document validation and correction in Preview.

This feature allows you to enhance extraction accuracy with validation rules and document data using Common Expression Language (CEL) dialect.

For more information, see CEL dialect for document validation.

Layout parser image and table annotations is in General Availability (GA).

Layout parser can identify if there are images or tables in parsed documents. When found, images and tables are annotated as a descriptive block of text with the information depicted in the image and table.

Upgrading fine tuned custom extractor processors is now available in Preview.

The feature allows you to fine tune a new processor version with a newer base version, while keeping the configurations of the previously fine-tuned processor version selected. This is available through the UI in the Deploy & use tab in the console.

This is currently supported for upgrading pretrained-foundation-model-v1.4-2025-02-05 to pretrained-foundation-model-v1.5-2025-05-05.

For more information, see training overview.

Document AI legacy processors will be discontinued on June 30, 2026. To preempt the risk of service failure while using legacy processors, we recommend transitioning to more stable, higher-quality processors.

The affected versions are:

To ensure uninterrupted service and benefit from improved extraction quality, we recommend you migrate to the following later versions before June 30, 2026:

• Enterprise Document OCR: Migrate to pretrained-ocr-v2.1-2024-08-07.

• Expense parser: Migrate to pretrained-expense-v1.3.2-2024-09-11.

• Custom classifier: Migrate to pretrained-classifier-v1.5-2025-08-05.

• Custom splitter: Migrate to pretrained-splitter-v1.5-2025-07-14.

• Invoice parser: Migrate to pretrained-invoice-v2.0-2023-12-06.

• Pay slip parser: Migrate to pretrained-paystub-v3.0-2023-12-06.

• Bank statement parser: Migrate to pretrained-bankstatement-v5.0-2023-12-06.

To learn more about the migration process, refer to Manage processor versions.

If you have any questions or require assistance, contact us at Google Cloud support.

The layout parser web interface is in Preview.

It supports a document view display for processed PDF files and supports visualizing the document's parsed JSON, block layout, and image or table annotation data in a user-friendly interface. Bounding box support only exists for version processor pretrained-layout-parser-v1.0-2024-06-03.

It also supports modifying the input layout config to allow for configuring the table and image annotation feature directly from the interface.

Layout parser model pretrained-layout-parser-v1.6-2026-01-13 powered by Gemini 3 Flash LLM is available in Preview.

This processor version has ML processing capabilities in the US and EU.

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

Layout parser model pretrained-layout-parser-v1.6-pro-2025-12-01 powered by Gemini 3 Pro LLM is available in Preview.

This processor version has ML processing capabilities in the US and EU.

For more information about available models, see the layout parser page.

Custom extractor model pretrained-foundation-model-v1.6-pro-2025-12-01 powered by Gemini 3 Pro LLM is available in Preview.

This processor version has ML processing capabilities in the US and EU.

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

Custom extractor model pretrained-foundation-model-v1.6-2026-01-13 powered by Gemini 3 Flash LLM is available in Preview.

This processor version has ML processing capabilities in the US and EU.

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

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).

Layout parser lets you parse images and tables as annotations in Preview.

Layout parser can identify if there are images or tables in parsed documents. When found, images and tables are annotated as a descriptive block of text with the information depicted in the image and table.

Capacity reservation is available for Document AI in Preview. This lets you grant capacity to selected processors and maintain a steady real-time, high-volume processing flow for document processing requests.

For the necessary steps, read the Make a capacity reservation request section of "Quotas".

Custom extractor model pretrained-foundation-model-v1.5.1-2025-08-07 with improved adaptive few-shot learning is available as Release Candidate (Preview).
