Managing processor versions

New versions are released for a variety of reasons, for example, to improve accuracy, increase availability, and support new document elements, such as selection marks.

Given that Document AI is powered by generative AI, future versions are using new foundation models so you can benefit from generative AI enhancements.

As we improve foundation models, earlier foundation models are deprecated. Similarly, processor versions are deprecated six months after new versions are released.

A processor can have one of the following versions:

This page describes how processors are versioned, and how to view and select a particular version.

Processor versions overview

There are two categories of processor versions:

  • Google versions are either stable (for production use cases) or release candidates (experimental with latest functionality).
  • User versions are created by you to customize predictions for your documents and have alphanumeric version IDs.

Google versions

Each Google version is identified by a Version ID, for example pretrained-TYPE-vX.X-YYYY-MM-DD. Each processor version Google offers is named either Google Stable or Google Release Candidate (RC).

Google stable versions

Stable versions are production-quality and ready for use.

  • Google prioritizes stability of the processor behaviour, but stills includes critical fixes
  • Earlier Google stable versions are deprecated six months after the newest stable version is released as depicted in the following figure.

managing-processor-versions-2

Google release candidates (RC)

Release candidates are experimental and are upgraded regularly with the latest features. These are not production-quality versions, and their stability isn't guaranteed.

Customized versions

Customized versions are the processor versions that you can create based on your documents to customize predictions. Customized versions have a Type, which shows the kind of model used for predictions. If you create a version using a foundation model (either by creating a version or fine tuning), then the type is Generative AI. If you create a processor version by training a smaller, custom model (either model or template based), then the type is Custom. If you create processor versions, you decide the name and ID.

Base versions

If you create a processor version, the "base version" shows which Google version powers your customized user version. The base version dictates the lifecycle of your user version. You need to make decisions about how to manage the lifecycle of your customized user version.

Processor version lifecycle

As soon as a new Google version is available, you should create and evaluate new user versions with the new base version. Then, deploy your new version and undeploy (or delete) earlier user versions that use the prior stable version as their base. Stable versions are discontinued after a new one is released. Google gives you at least six months' notice when this occurs.

What happens when a base version is deprecated?

User versions depending on earlier base versions stop returning predictions when the base version is deprecated.

How are processor versions selected for your requests?

When you call a processor endpoint without specifying the processor version, the default processor version is used. When the default processor version changes, you might need to update the code.

Endpoint used Experience
If you do not specify a processor version ID Requests processed using a new default processor version.
If your default processor version is deprecated, the default updates to the most recently launched stable Google version when the older default version is deprecated.
If you specify the processor version ID The response fails if you call a processor endpoint and specify a version ID which has been deprecated.

Deprecation example of a customized version

Consider the following scenario that describes the sequence of events in a customized version deprecation:

  1. As a developer, you're using a Custom Extractor to get data from documents. Given the complexity and volume of documents you process, you fine tune the foundation model to create a version named fine-tune-A. You set the fine-tune-A version as the default version for your processor and use it to process documents. The base version that powers the fine-tune-A model is the pretrained-foundation-model-v1.0-2023-08-22 (v1.0) stable version.

  2. Google published a new stable version named pretrained-foundation-model-v2.0-2024-02-22 (v2.0) and announced that the v1.0 stable version is to be deprecated on August 22, 2024.

  3. Since you kept your training and test documents in your processor's dataset, you fine-tune another version based on the newest Google stable version, v2.0, and name it fine-tune-B. After you evaluate its performance, you set the fine-tune-B version as the new default version for your processor and decommission the fine-tune-A version. Your new version now uses the latest supported Google stable version.

On the other hand, had you not created and evaluated the customized fine-tune-B version, then Google would have updated the default version of your processor to v2.0 on August 22, 2024. Because you are calling the processor's endpoint and not specifying a processor version, the new v2.0 version is used as the new default to process your requests.

Select a processor version

There are three ways to specify which processor version to use for online and batch processing:

  • If you do not specify a version, the processor's default is used.

    • Example: projects/my-proj/locations/us/processors/my-processor:process
  • If you specify a version, then that specific version is used. If the specific version does not exist, the request fails with an error.

    • Example: projects/my-proj/locations/us/processors/my-processor/processorVersions/pretrained-invoice-v1.2-2022-02-18:process
  • If you specify a channel then the latest version in that channel is used. (Options: stable, rc)

    • Example: projects/my-proj/locations/us/processors/my-processor/processorVersions/stable:process

View available version

Console

  1. In the Google Cloud console, in the Document AI section, go to the Processors page.

    Go to Processors

  2. From the list of processors, click the name of the processor that you want to view details for.

  3. Select the Manage Versions (or Deploy & use) tab, which will display all of the available processor versions.

REST

Change the default version

A processor's default version specifies the version that is used to process documents when you don't specify a specific version. When you create a processor, the initial default version is the latest version in the stable channel.

If you change the default version, incoming requests are processed using the newly selected version. If you change the default version while the processor is in the middle of a request, the request will continue to use the previously selected version.

To change the default version:

Console

  1. In the Google Cloud console, in the Document AI section, go to the Processors page.

    Go to the Processors page

  2. From the list of processors, click the name of the processor that you want to view details for.

  3. In the processor's Manage Versions (or Deploy & use) tab, in the Default version dropdown menu, choose a version of the processor that you want to use as the default version.

REST

This sample shows how to set the default processor version for your processor using the processors.setDefaultProcessorVersion method.

Before using any of the request data, make the following replacements:

  • LOCATION: your processor's location, for example:
    • us - United States
    • eu - European Union
  • PROJECT_ID: Your Google Cloud project ID.
  • PROCESSOR_ID: the ID of your custom processor.
  • PROCESSOR_VERSION: the processor version identifier. Refer to Select a processor version for more information. For example:
    • pretrained-TYPE-vX.X-YYYY-MM-DD
    • stable
    • rc

HTTP method and URL:

POST https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:setDefaultProcessorVersion

Request JSON body:

{
  "defaultProcessorVersion": "PROCESSOR_VERSION"
}

To send your request, choose one of these options:

curl

Save the request body in a file named request.json, and execute the following command:

curl -X POST \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:setDefaultProcessorVersion"

PowerShell

Save the request body in a file named request.json, and execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
-Method POST `
-Headers $headers `
-ContentType: "application/json; charset=utf-8" `
-InFile request.json `
-Uri "https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:setDefaultProcessorVersion" | Select-Object -Expand Content

The response is a long running operation. To poll the long-running operation, call operations.get

The SetDefaultProcessorVersionMetadata in the response indicates the state of the operation.

Import a processor version

After creating a new processor with Document AI, you can import a processor version from the same or a different project.

The destination project is where you begin the import and where the processor version becomes available after the import.

The source project is where the source processor version lives.

The source or destination processors must meet the following requirements to import:

  • Processor types must match. Examples: CUSTOM_EXTRACTION_PROCESSOR or INVOICE_PROCESSOR
  • Processor schemas must not conflict.
  • Destination processor can have existing datasets and versions.
  • Destination processor must be in ENABLED state.
  • Source processor version must be in one of the following states:
    • DEPLOYED
    • DEPLOYING
    • UNDEPLOYED
    • UNDEPLOYING

You must grant the DocumentAI Core Service Agent of the destination project Document AI Editor permission on the source project to avoid a permission denied error.

Complete the following steps to set up permission before importing a processor version:

Console

  1. Look up DocumentAI Core Service Agent and fill in your destination project number. The DocumentAI Core Service Agent is formatted like an email address. For example: service-123@gcp-sa-prod-dai-core.iam.gserviceaccount.com

  2. Open the IAM page in the Google Cloud console.

    Open the IAM page

  3. Select your source project.

  4. Click grant access.

  5. Add the destination project's DocumentAI Core Service Agent as a new principal, and assign Document AI Editor role.

gcloud

Use the following gcloud command to grant the necessary permissions:

gcloud projects add-iam-policy-binding SOURCE_PROJECT \
    --member=serviceAccount:service-DESTINATION_PROJECT NUMBER@gcp-sa-prod-dai-core.iam.gserviceaccount.com \
    --role=roles/documentai.editor

Provide the following values:

  • SOURCE_PROJECT: The source project number or project id.
  • DESTINATION_PROJECT NUMBER: The destination project number.

After updating the permissions, use the following steps to import a processor version:

Console

  1. In the Google Cloud console, in the Document AI section, go to the Processors page.

    Go to the Processors page

  2. From the list of processors, click the name of the processor that you want to import a processor version to as a destination processor.

  3. Go to the Manage Versions (or Deploy & use) tab, and click Import.

  4. Choose the project, the processor, and the processor version as the source processor version in the window.

  5. Click IMPORT button in the window, and the import operation will start.
