What is hallucination and LLM? To understand the world of AI in 2026, definitely know these 10 words:

News India Live, Digital Desk: By the year 2026, Artificial Intelligence (AI) is no longer just a thing in the lab, but it has reached from our smartphones to our kitchens. But when we read about AI, words like ‘machine learning’, ‘neural networks’ and ‘deepfakes’ confuse us.

If you don’t want to lag behind technologically, then look carefully at this decoding list of AI. These are the words that will determine the digital literacy of the future.

1. Generative AI

This is the branch of AI that is capable of creating new content. Be it text, image or video. It does not just process data, but creates new ones.

2. Large Language Model (LLM)

Just as humans learn language by reading books, LLMs (like ChatGPT or Gemini) understand language by reading trillions of words and sentences and respond like humans.

3. AI Hallucination

It is very important to understand this word. When AI confidently gives wrong information or presents imaginary facts, it is called ‘hallucination’. Therefore, AI responses should always be cross-checked.

4. Neural Network

It is a computer system based on the functioning of the human brain. It helps the machine to find hidden patterns among the data.

5. Machine Learning

This is the part of AI that gives computers the ability to learn on their own from past experience and data, without being programmed separately.

6. Computer Vision

When AI looks at photos or videos and recognizes them and analyzes them (like face unlock or medical scanning), it’s called computer vision.

7. Algorithm

It is a set of instructions that AI follows to solve a problem or complete a particular task.

8. Ethical AI

Since AI is very powerful, the rules for using it without discrimination and safety are called ‘Ethical AI’.

9. Prompt Engineering

Giving the right prompt to AI to get it to do the right work is an art. It has become the most in-demand skill in 2026.

10. AI Agents

These are autonomous programs that not only respond, but can also perform tasks on your behalf, such as sending emails, booking tickets, or managing projects.
