Guardrails in AI are built-in safety mechanisms, such as rules or filters, designed to prevent artificial intelligence systems from generating harmful, unsafe, or inappropriate content. These guardrails help ensure that AI tools act responsibly and do not provide information that could be dangerous, offensive, or misleading. By setting clear boundaries on what AI can and cannot do or say, guardrails protect users and reduce the risk of AI being exploited for malicious purposes. Strong guardrails are essential for maintaining trust and safety in AI-powered applications.
