抖阴成年 AI third-party partners, such as OpenAI and Google, are contractually prohibited from using any customer data to train their models. Additionally, where applicable, we have established systemic controls to turn off third parties鈥 abuse-monitoring solutions to ensure there is no human access to 抖阴成年 customers鈥 data or inclusion of that data in third-party models.
We have developed and implemented prompting 鈥済uardrails,鈥 ensuring our AI-based products will only produce responses from content drawn from a clearly defined and limited set of verified information, such as the human validated content from products such as Westlaw, Practical Law, and Checkpoint. This practice restricts the large language model鈥檚 ability to produce potentially objectionable content broadly sourced from the internet.
