AGI Fundamentals — A Comprehensive Introduction
A precise, neutral introduction to artificial general intelligence: definitions, history, capability levels, misconceptions, milestones, and the vocabulary of the field. Current for 2026.
Artificial general intelligence — AGI — is the working name for a hypothetical machine system that can match or exceed competent human adults across the full range of cognitive work, not only on tasks it was explicitly trained for. It is a research goal, not a deployed product.
The public conversation often conflates AGI with today's chatbots, with science-fiction superintelligence, or with consciousness. This hub keeps those threads separated. Each article gives you a precise definition, the relevant research history, the current state of the art in 2026, and the open questions that still divide serious researchers.
Start with What Is AGI? for the definition, then read AGI vs AI to see how the term differs from the narrow systems already in production. The Five Levels of Machine Intelligence and AGI Milestones to Watch give you a framework for tracking progress without falling for hype.

What Is AGI? A Precise Definition for 2026
Artificial general intelligence (AGI) defined: a system that matches or exceeds competent human adults across the cognitive tasks required for most economically valuable work, without being retrained for each one.

AGI vs AI: What's Actually Different
Today's artificial intelligence solves specific tasks extremely well. AGI is a hypothesised system that solves the full range of cognitive tasks. The differences are in scope, transfer, autonomy, and robustness.

AGI vs Human Intelligence: Where the Comparison Holds and Breaks
Human general intelligence is the benchmark AGI is measured against. It includes language, reasoning, memory, embodied perception, social cognition, and the capacity to learn continuously across a lifetime.
