A RAG application on Amazon Bedrock pulls financial news for daily newsletters, and users report politically biased content. Which Bedrock guardrail can detect and block that type of content?

Content filters are the most appropriate Bedrock guardrail for detecting and blocking politically biased content. They allow you to define categories of harmful content, such as hate speech, insults, or, in this case, biased language, and then configure thresholds to block or flag content that falls into these categories. Word filters are too granular and would require an exhaustive list of biased terms, which is impractical and prone to missing nuances. Denied topics are designed to prevent discussion of specific subjects, not to filter for bias within a topic. Sensitive information filters protect personal identifiable information (PII) or other confidential data, which is unrelated to political bias.
