AI Glossary Term
What does “Safety Filter” mean?
Definition
A moderation layer that blocks or rewrites unsafe model inputs or outputs.
How Safety Filter works
Example
A chatbot for kids has a layer that checks each reply. If a draft contains disallowed content, the filter blocks it or replaces it with a safe message before it appears.
Why it matters
Filters add a defense independent of the model's own training. They can wrongly block harmless content or miss clever evasions.
Common questions
What do filters catch?
Categories such as hate, self-harm, explicit content, or personal data, depending on how they are set up.
Are they perfect?
No. They produce both false positives and false negatives.
Are filters built by classifiers?
Often, a smaller model or rule set scores text for risk categories.
