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.
