Should I use built-in model safety features or add separate content filters?

Both. Built-in model safety (Anthropic's Constitutional AI, OpenAI's content policies) provides a baseline. Add separate content filters for your specific policies: brand guidelines, industry regulations, topic restrictions, and PII handling. Model safety prevents broadly harmful content; custom filters enforce your business-specific rules. Defense in depth is the standard approach.

Content Filter

A system that screens AI agent inputs and outputs for harmful, inappropriate, or policy-violating content before it reaches users or downstream systems. Content filters operate at multiple levels: profanity and toxicity detection, PII redaction, copyright infringement checks, brand safety enforcement, and topic restriction. Filters are essential guardrail components—they prevent agents from generating or relaying content that could harm users, violate regulations, or damage brand reputation.

Example

A social media AI agent has content filters that check every post before publishing: no profanity, no competitor mentions, no unsubstantiated product claims, no PII, and no content that could be interpreted as financial advice. A post mentioning a competitor by name is caught by the filter and rerouted to a human for review.
