Adobe Stock, which licenses photos, illustrations, and videos to creative professionals, requires contributors to label any content made with AI tools before submitting it. Adobe also uses automated systems to detect policy violations — such as AI images depicting real people or referencing copyrighted characters — and has removed thousands of assets for breaking these rules. This policy launched in December 2022.

Contributors must check a "Created using generative AI tools" checkbox at upload, and Adobe's systems categorize and review AI-generated content for policy compliance. Prohibitions include prompts referencing named artists, real individuals, fictional characters, and third-party intellectual property. AI-generated content is banned from the Illustrative Editorial collection. Content Credentials are attached to AI-generated assets when downloaded. Adobe pays an annual Firefly Contributor Bonus to Stock contributors whose licensed content was used to train Firefly, though contributors have no opt-out and were not given specific consent for training use.
