Anthropic has announced a significant update to its privacy policy, allowing the company to use conversations from its Claude chatbot as training data for future models unless users explicitly opt out. This change, effective from October 8, aims to improve the chatbot's performance by leveraging real-world interactions to refine its responses. Users will encounter a prompt during sign-up or may see a pop-up if they are existing users, with the default setting opting them into data usage. Additionally, the retention period for user data has been extended from 30 days to five years, regardless of whether users consent to model training. This policy shift positions Anthropic alongside other major AI companies that already utilize user data for model training, highlighting a growing trend in the industry.
