  "account": "This article explores two techniques to optimize AI usage: semantic caching and live internet search. Semantic caching saves costs by remembering answers to frequently asked, similar questions, while live internet search allows the AI to fetch real-time data when needed. The decision to use caching or search depends on the question's similarity and urgency. Semantic caching has three main risks: providing wrong answers due to similar questions, outdated information, and sharing incorrect answers with other users. Live internet search offers real-time answers at the cost of additional API fees and slower response times. The two methods work together, with a sorting step determining the appropriate approach for each question.",
  "summary": "Say you open the logs of your chat system and they are full of questions like these: \"How do I change my password?\" \"Forgot my password, what do I do?\" \"Where do I reset my password?\" All three mean the same thing. But the system sent each one to the AI, had it write a fresh answer three times, and paid for the tokens three times. Multiply that by thousands or tens of thousands of users, and the…",
