AI Model vs. Chatbot App: What's the Difference?
Model vs. App
The model is the trained engine that turns text into more text. A chat app is the product wrapped around it: a text box, a conversation history, maybe file uploads or a web search tool.
When a chat app "looks something up", it is usually the app fetching information and handing it to the model as extra text. The model itself only ever sees text going in and produces text coming out.
Keeping these two ideas separate helps you understand why the same model can feel different inside different apps.
