We have developed and implemented prompting "guardrails," ensuring our GenAI-based products will only produce responses from content drawn from a clearly defined and limited set of verified information, such as our own content databases. This practice restricts the large language model's ability to produce potentially objectionable content broadly sourced from the internet.
