In late 2024, a Canadian tribunal compelled Air Canada to honor a discount erroneously cited by its AI chatbot, which fabricated a "bereavement fare" policy, highlighting the risks of AI hallucinations—where AI systems produce convincing yet false information. Such incidents emphasize the potential legal liabilities and brand damage when AI models generate incorrect data, whether in contracts, medical advice, or compliance rules. The text details various examples of AI errors across industries like procurement, banking, healthcare, and manufacturing, illustrating the business costs and operational disruptions caused by AI-generated fabrications. To mitigate these issues, enterprises can deploy observability techniques and guardrail tactics, such as real-time monitoring, validation checks, and multi-source verification, which help detect and prevent AI hallucinations before they cause significant harm. The narrative also introduces Galileo, a platform that integrates into development workflows to provide automated quality guardrails, real-time protection, and human-in-the-loop optimization, aiming to achieve zero-error AI systems that maintain user trust and comply with regulatory standards.
