Guardrails (AI Safety Mechanisms)
Guardrails are technical and organisational safeguards intended to stop an AI system from producing harmful, incorrect, discriminatory or reputationally damaging output. They work on several levels: on inputs through filters against prompt injection, during processing through clear rules of behaviour, and on outputs through checks against false information or brand guidelines before a response reaches users.
In practice
For companies running a chatbot or AI agent on their own website, guardrails matter in order to avoid reputational damage – a bot promising the wrong prices, replying inappropriately or revealing confidential internal information, for example. Typical set-ups combine clear system prompts, blocklists for sensitive topics, automated output checks and spot checks by a person. Guardrails do not replace fundamental quality assurance, but they noticeably reduce the risk of hallucinations and misbehaviour in production AI applications.
