Day 1: What AI Is
Goal
Understand AI as software that learns patterns from data and uses those patterns to help with tasks.
Learn
AI is a broad field, not one product. Modern AI systems can classify images, generate text, summarize documents, answer questions, write code, make images, analyze data, and operate tools. The key idea is pattern learning: the system is trained on examples, then uses statistical structure from those examples to respond to new inputs.
Example
A photo app groups similar faces, a chatbot drafts text, and a search assistant summarizes sources. Each tool uses learned patterns for a different job.
Practice
Open one chatbot and ask it to explain the same topic at three levels: child, high school, and professional. Notice how the same model changes style based on instructions.
