Add Image Moderation to OCI Generative AI Guardrails

You can now use the ApplyGuardrails API in OCI Generative AI to moderate image inputs through the existing content moderation capability. Image moderation is available with Guardrails system version 1.1.0.

This feature helps identify unsafe content in standalone images or multimodal requests that include both text and images. You can use it to evaluate user-uploaded images, generated images, screenshots, and images that contain embedded text.

To use image moderation, submit the request with multimodalInput, include an item with "type": "IMAGE", enable contentModerationConfig, and specify Guardrails system version 1.1.0 using guardrailVersionConfig.

Supported image formats include:

• JPEG
• PNG
• WebP

A single request can include up to five images, and each image can contain up to 170 megapixels. Image inputs are also subject to image-token throttling, with a default limit of about 200,000 image tokens per minute. If you need a larger image-token limit, you can request a service limit increase.

Image moderation doesn't introduce a separate response object. Results are returned as part of the existing contentModeration result, including the OVERALL score. The new flaggedModalities field identifies which modality contributed to the moderation result. Supported values are TEXT and IMAGE.

Example response excerpt:

{ "name": "OVERALL", "score": 1.0, "flaggedModalities": ["TEXT", "IMAGE"] }

Our Content Moderation (CM) and Prompt Injection (PI) guardrails have been evaluated on a range of multilingual benchmark datasets. However, actual performance may vary depending on the specific languages, domains, data distributions, and usage patterns present in customer-provided data as the content is generated by AI and may contain errors or omissions.

The OCI Responsible AI team is continuously improving these models.
