Types of AI (Narrow, General, Super) — Tutorial
Understand the three capability tiers and what we actually have today
Overview
Level: Beginner. Estimated reading time: 10 minutes.
Narrow AI — the only kind that exists today
Narrow AI (also called Weak AI) is designed for one specific task. A chess engine beats world champions but cannot write an email. GPT-4 generates fluent text but cannot play chess at the same level. Image classifiers identify tumors but cannot drive a car.
Every AI system in production today — recommendation engines, fraud detectors, LLMs, image generators, self-driving prototypes — is Narrow AI. Each is a specialist, not a generalist.
Artificial General Intelligence (AGI)
AGI describes a hypothetical system that matches human cognitive ability across all domains — it could switch from writing code to diagnosing disease to learning a new language with the same facility a human can.
No AGI exists today. Definitions vary (some researchers argue frontier LLMs show early AGI precursors; most disagree). The AI safety field treats AGI as the central long-term risk to plan for, regardless of the timeline uncertainty.
Superintelligence and the media hype gap
Superintelligence would surpass human capability across all domains by a large margin. It is purely theoretical and no credible timeline for its arrival is established.
Most day-to-day "AI" headlines describe Narrow AI advances. Reading those stories with the Narrow/General/Super framework prevents confusion: a model that aces the bar exam is still Narrow AI — it was trained on legal text and optimised for that task.
