The best way to assess AI output is to rely on your own knowledge: the more facts you can verify, the more confidence you can have in the response. When working outside your area of expertise, carefully review accuracy, relevance, and alignment with your goals, as there are no universally accepted metrics for evaluating AI-generated content.
In practice, AI is most effective when used in domains where you have sufficient expertise to validate its outputs. For important decisions, always have subject matter experts review AI-generated recommendations to reduce the risk of errors or overlooked assumptions.
