Opting Out of AI Training Datasets

Most large AI models are trained on material collected from the web. Common Crawl publishes huge crawls of the public internet, and image datasets such as LAION-5B, with about 5.85 billion image and caption pairs, were built by filtering them. LAION distributes links and captions rather than image files, but models trained with it downloaded the images from those links. To check whether your work appears, Spawning's Have I Been Trained lets you search LAION datasets by text or image. It covers only the datasets it indexes; there is no way to search the private data many companies use. The main prevention tools are: robots.txt. Many AI companies publish crawler names that sites can block, including GPTBot (OpenAI), ClaudeBot (Anthropic), CCBot (Common Crawl), Applebot-Extended (Apple) and Google-Extended, which controls use in Google's Gemini models without removing a site from Google Search. Some hosts and CDNs, such as Cloudflare, offer one-click AI crawler blocking. Platform settings. Services like LinkedIn and X have offered settings controlling training on user content, and Meta has offered objection forms in regions with stronger data protection law. Art sites such as DeviantArt and ArtStation introduced NoAI tags. Registries and legal reservations. Spawning's Do Not Train registry records opt-outs that some companies, including Stability AI for certain models, said they would honor. In the EU, the 2019 copyright directive allows rights holders to reserve text and data mining rights in machine-readable form, and the EU AI Act requires general-purpose model providers to respect such reservations. The limits are important. robots.txt is voluntary and not enforcement. Opt-outs are not retroactive, and trained models do not forget. Copies of your work reposted elsewhere are not covered by your site's rules. Blocking crawlers can also reduce visibility in AI-powered search. Opting out lowers exposure; it does not guarantee exclusion.
