Imagine having a robot you could chat with about anything - your favorite video games, help with homework, or even about the weather. This isn't science fiction; it's a reality made possible by something called Chat GPT. Chat GPT is a type of Artificial Intelligence (AI), which is like a digital brain. It's designed to understand and respond to human language. It's like a parrot that repeats not just words but whole ideas it learned from a massive collection of text from the internet. But unlike a parrot, GPT can make the conversation meaningful and sensible. You might wonder, where can we use Chat GPT? Well, you could find it replying to customer queries on websites, tutoring students online, or even in mobile apps for entertainment. Imagine being stuck on a tricky math problem, and a friendly AI helps you out. Or, you're bored and have a humorous conversation with an AI. That's Chat GPT in action!
