What an AI solution actually is here
An AI solution is a production system with a model inside it, and the model is the smallest part. Around it sits the ingestion that gets your data in, the retrieval that finds the right passage, the schema that forces an answer into a usable shape, the evaluation that proves it works on your cases, and the logging that lets you audit it afterwards.
Leave any of those out and you have a demo — convincing in a meeting, unreliable in the first week it meets real inputs.
