What is AI, really?

4 min read

"AI" (artificial intelligence) is a broad name for computer programs that do things we used to think needed a human: understanding language, recognising faces in photos, translating, or writing.

The AI you hear about today

Tools like ChatGPT, Claude and Gemini are built on large language models. A language model is trained on a huge amount of text and learns patterns in how words follow each other. When you ask a question, it predicts a helpful-sounding answer one piece at a time.

Image and music tools work in a similar spirit: they learned patterns from many examples and generate something new that matches your description.

What it's good at

• Drafting: emails, captions, summaries, outlines.
• Explaining: "explain this like I'm 12" works surprisingly well.
• Brainstorming: names, ideas, plans, lists.
• Transforming: translate, shorten, change tone, turn notes into a table.

What it's bad at

• It can state wrong facts confidently (this is called a "hallucination").
• It may not know about very recent events unless it searches the web.
• It doesn't truly know you or your situation; it only knows what you tell it.

Three rules to stay safe

• Check anything important (health, money, legal) with a trusted source.
• Don't paste passwords, OTPs, Aadhaar or bank details into a chatbot.
• Read what it wrote before you send it under your name.

That's it. You don't need to understand the maths to get value. You just need to practise asking clearly.
