Artificial intelligence, or AI, might seem like magic, but it actually works in a very logical way. AI does not think or feel like a human. Instead, it looks at data, finds patterns, and uses those patterns to make predictions.
What AI Really Is
AI is a computer program that learns from examples. It is trained on large amounts of data such as articles, books, and websites. By seeing many examples, AI learns what usually comes next in a sentence, an image, or a piece of code.
AI does not understand meaning. It only learns what is most likely to be correct based on what it has seen before.
How AI Learns
Most modern AI uses something called machine learning. During training, the AI is shown lots of examples and asked to predict the correct answer. When it gets something wrong, it adjusts itself and tries again. Over time, it gets better at making accurate predictions.
This learning happens inside a structure called a neural network, which is made up of many layers of math calculations.
How AI Answers Questions
When you type a question into an AI tool, the AI breaks your sentence into small pieces called tokens. It then predicts the next token one step at a time until it finishes the response.
The AI chooses words based on probability, not facts. This is why it can sometimes give wrong answers even if it sounds confident.
Why AI Makes Mistakes
AI can make mistakes because it does not check facts on its own. It only predicts what sounds correct. If the data it learned from was incomplete or outdated, the answer might be wrong.
This is why humans still need to review and verify AI responses.
The Bottom Line
AI works by learning patterns from data and using those patterns to predict answers. It is a powerful tool that can help people learn, write, and solve problems, but it is not a replacement for human thinking.
