Some large AI customers are restricting which models employees may use or which tasks they may use them for over fears proprietary information could be used in training, The Information reported. Nvidia uses Fable only for work that does not require sensitive-data access, while a U.S. utility canceled a Fable test after Anthropic would not agree to a nonrevocable zero-data-retention policy. Anthropic and OpenAI say enterprise-contract customer information is not used for training by default.
