DeviantArt uses an AI detection system to automatically identify artwork created with AI tools, supplementing a mandatory user labeling requirement that went into effect in June 2023. Detected or labeled AI art can be suppressed from a user's browsing feed at their discretion.

Starting June 12, 2023, DeviantArt required users to label submissions made primarily with AI tools as 'Created using AI tools.' In July 2023, DeviantArt updated the system to automatically apply this label when an image's embedded metadata indicates it was created with AI — metadata that is embedded by most major AI generation tools. A separate AI detection model also attempts to identify AI-generated images that lack proper labeling, enabling the platform's 'Suppress AI' browse setting to filter out such content. DeviantArt has stated that detection accuracy is imperfect and improves over time as more artists correctly label their work.
