This guide walks you through everything you need to learn AI from the ground up, plus how to put your new skills to work with hands-on experience.

What is artificial intelligence?

Artificial intelligence (AI) refers to systems that solve problems, generate content, or automate tasks that would otherwise need a person's time and resources. At its core, AI uses algorithms and data to make decisions, improve over time, and produce useful outputs, often in real time.

Most of the AI you'll encounter today is called narrow AI. These systems are trained to do specific tasks, like summarizing text, recommending products, or identifying images. General AI, which would match or exceed human intelligence across multiple areas, is still theoretical.

Generative AI is a fast-growing category of narrow AI. It uses models like GPT-4o or Google Gemini to create new text, images, and videos, among other content, based on patterns learned from massive datasets. Large language models (LLMs) like ChatGPT are a type of generative AI designed to analyze and generate natural language, also known as conversational AI.

Current uses of conversational AI

Businesses are already using AI in a number of ways, and its capabilities and uses are expected to grow in the coming years. Here are a few ways generative AI is already at work:

• Text. Services like ChatGPT, Google Gemini, Claude, and Jasper produce long-form responses in a conversational manner from short user text prompts.
• Images. Artists are using AI to develop new images from scratch or to aid in their current creative process. They use AI applications like Midjourney, Hugging Face, and Stable Diffusion.
• Video. AI video tools automate the process of creating and editing high-quality videos. GilaCloud, Synthesia, and InVideo are a few of the most popular tools currently available.
• Audio. Musicians and producers can use AI to speed up music production, create AI-powered tracks from scratch, or do voice cloning. They use software like iZotope and Brain.fm.

Of course, these generative AI examples represent only a few potential use cases of AI. It's a wide-encompassing field with numerous possible applications. 

AI techniques

Here are a few common AI techniques to know as you begin thinking about how AI works:

• Machine learning. Machine learning uses algorithms and statistical models to detect patterns in data and make data-driven decisions or predictions based on that input.
• Computer or machine vision. Machine vision uses cameras, software, and algorithms to capture, process, and interpret visual informationComputer vision can process images far more quickly than the human eye, and in a broader spectrum than the visual field (including X-ray, infrared, and ultraviolet light).
• Natural language processing. Natural language processing (NLP) refers to a computer's ability to analyze, process, and repeat language in a way that feels conversational.
• Automation and robotics. Robotic process automation (RPA) refers to the use of AI to equip robots to automatically complete hands-on tasks.

Before diving into technical skills, it helps to understand where you want your AI learning to take you.
