The National Center for Missing and Exploited Children said it received more than 1 million reports of AI-related child sexual abuse material (CSAM) in 2025. The "vast majority" of that content was reported by Amazon, which found the material in its training data, according to an investigation by Bloomberg. The spokesperson also said that Amazon aimed to over-report its figures to NCMEC in order to avoid missing any cases. The company said that it removed the suspected CSAM content before feeding training data into its AI models. In accordance with our commitments to responsible AI and the Generative AI Principles to Prevent Child Abuse, we take a deliberately cautious approach to scanning foundation model training data, including data from the public web, to identify and remove known CSAM and protect our customers.
