Text moderation enhanced plus-AI Guardrails(AI Guardrails)-阿里云帮助中心

Text Moderation Enhanced Edition has been upgraded to the PLUS service, allowing you to enable or disable moderation labels. This topic explains how to use the service.

After the service is activated, it cannot be completely disabled. To stop specific detection, disable the corresponding detection label on the Rules page.

Risk labels

Label description

Text Moderation Pro can return over 60 granular risk labels across 10 categories, each with a confidence score. If content contains multiple risks, the service can return multiple labels for a single request. The following table describes these risk labels, their confidence score ranges, and their meanings.

Manage labels

You can enable or disable each risk label in the console. Some risk labels provide switches for more granular detection scopes. For more information, see the Content Moderation Console.

In the left-side navigation pane, choose Content Moderation Pro > Text Moderation > Rule Configuration.
On the Rule Management tab, for the llm_query_moderation service, click Modify Rules in the Actions column.
1. Select the detection type you want to adjust, for example, Unwanted Content Detection.
2. Click Edit, then modify the status of the detection item.
3. Click Save. The new configuration takes about 2 to 5 minutes to take effect. If you disable a detection label, it may take longer than 2 to 5 minutes to take effect, and some labels may not take effect until the next day (T+1).

Troubleshooting: content still blocked after disabling a label

If the API still returns a detection label after you disable it in the console, troubleshoot as follows:

Confirm that the switch status in the console is Disabled and that the save operation returned Saved.
Confirm that the Service parameter in your API request matches the Service configured in the console.
Wait 5 minutes, and then call the API again with the same content to verify.
Check whether the Service list page displays the message "The usage status of the Service will be updated on T+1". Some labels may take effect on the next day instead of within 2 to 5 minutes after you disable them.
If the change has still not taken effect after 10 minutes, record the RequestId for troubleshooting with backend support.

Enable a Service

On the Rule Configuration page, each Service is listed as Unused by default. You do not need to activate a Service; after configuring its detection rules, you can use it by making an API call.

Log on to the Content Moderation Console.
In the left-side navigation pane, choose Content Moderation Pro > Text Moderation > Rules.
In the Service list, find the target Service, such as comment_detection_pro, and click Modify Rules in the Actions column.
On the Detection Scope tab, enable or disable the required detection items, then click Save. The changes take effect in about 2 to 5 minutes. If you disable a detection item, it may take longer than 2 to 5 minutes to take effect, and some items may not take effect until the next day (T+1).
(Optional) To use a custom dictionary for keyword detection, return to the Service list and click Set Thesaurus in the Actions column.
When making an API call, set the Service parameter to the corresponding Service name, such as comment_detection_pro.

Integration

Step 1: Activate the service

Visit Activate Service to activate the Content Moderation Enhanced Edition.

Step 2: Grant permissions to a RAM user

Before you use the SDK or call the API, you must grant permissions to a RAM user. To authenticate API calls, use an access key from either your Alibaba Cloud account or a RAM user. For more information, see Obtain an access key.

Grant permissions to a RAM user

Log on to the RAM console using your Alibaba Cloud account.
Create a RAM user. For details, see Create a RAM user.
Grant the AliyunYundunGreenWebFullAccess system policy to the RAM user. This policy grants full access to Content Moderation. For details, see Manage RAM user permissions.
The RAM user can now call the Content Moderation API.

Step 3: Install and integrate the SDK

For the SDKs for the Content Moderation Enhanced Edition PLUS service, see SDKs and integration guide for the Content Moderation 2.0 PLUS service.

API

Usage

Call this operation to create a text moderation task. To learn how to build an HTTP request, see native HTTPS call. Alternatively, use a prebuilt HTTP request. For details, see getting started.

Use OpenAPI Explorer to run this API directly without having to calculate the signature. Upon a successful request, OpenAPI Explorer automatically generates SDK code examples.

Billing: This is a paid API. You are only charged for requests that return a 200 HTTP status code; requests that result in an error are not charged. For more information about our billing method, see the billing description.

QPS limit

This API is subject to a single-user QPS limit. Exceeding this limit triggers API throttling and can disrupt your service.

AI-generated text detection (text_aigc_detector): 50 requests per second.
LLM-based UGC text moderation service (ugc_moderation_byllm_pro, ugc_moderation_byllm, and ugc_moderation_byllm_cb): 50 requests per second.
Other services: 100 requests per second.

Note

The UGC text moderation large model service has a lower QPS limit than other services. If your request volume is high, implement traffic control to avoid exceeding this limit.
