What is System Prompt?
Hidden instructions that configure how the AI behaves before you start talking to it.
// Explanation
When you use ChatGPT, Claude, or any AI app, there are instructions you can't see that tell the model how to behave: its personality, what it can and can't do, what language to respond in, etc. Companies use this to create specialized versions of a generic model.
// Example
When a customer support chatbot 'only knows how to talk about the company's products', that's a system prompt telling it not to discuss anything else.
