Artificial intelligence
From the basics of AI and how it learns to generative models, agents, everyday use and safety. Read one concept, then follow the links to the technologies around it.
Basics1/5
What AI is and how it learns. Start here and the rest gets easier.
- Artificial intelligence (AI)Technology that lets computers do things that people do by learning and judging.
- Machine learning (ML)A method where a computer finds the rules by itself from data, without a person writing each rule.
- Deep learningA machine learning method that stacks neural networks many layers deep so they learn complex features of photos, speech and text.
- Neural networkA computing structure modeled on how nerve cells in the brain connect to each other. It is the backbone of today's AI.
- AlgorithmA set of steps and methods decided in advance to solve a problem. A computer works by following those steps.
- Generative AIAI that creates new things, such as text, images, music, video and code.
- ChatbotA program that talks with people in text or speech and answers what they ask.
- LLM (large language model)An AI that has read a huge amount of text and learned to continue it by writing the next words.
- Natural languageThe speech and writing people use every day. The name sets it apart from programming languages made for computers.
- TokenThe small pieces of text an AI reads and writes. Also the unit that measures usage and price.
- PromptThe request or instruction you give to an AI.
- HallucinationWhen an AI states something untrue as if it were fact, with full confidence.
- Training and inferenceTraining is when an AI learns from data. Inference is when the trained AI actually produces answers.
- Training dataThe text, images, sound and other material shown to an AI when it is taught. What it learned from decides how good it is.
- ParameterThe numbers inside an AI model that are set by training. They usually indicate the size of the model.
- Context windowThe amount of text an AI can see and remember at one time.
- AGI (artificial general intelligence)A term for AI that can do the full range of intellectual work people do, about as well as people, not just one or two tasks.
- Superintelligence (ASI)A term for AI that does almost everything far better than the best humans. It does not exist yet and is an imagined stage.
