Many people are excited about Generative AI, but building AI systems for businesses takes a lot of work. People used to think you could just add some documents to an AI prompt and get a perfect system, but that's not true. To make AI work well, you need to break down big problems into smaller ones and focus on specific areas, like customer service for ordering and delivery. This makes it easier to test and make sure the AI is giving accurate and trustworthy answers. There are still challenges, like teaching AI to understand images and PDFs as well as humans do. But as AI gets cheaper and better, it will be used in more ways. One exciting development is AI agents that can use tools and work together to solve problems.
