An AI caching system designed to reduce model call expenses by storing and reusing answers to similar questions was found to be flawed. The cache used embeddings to determine similarity, treating questions with similar topics as identical, even when their meanings were opposite. This led to incorrect answers, such as advising a user on how to cancel an order when they intended to prevent cancellation. The author suggests that caches should only be used for static information and that action-dependent queries or those involving money should always go to the model or use exact question matching. AI
