Which type of AI is focused on specific tasks and lacks generalization?

Narrow AI refers to artificial intelligence systems designed to perform a specific task or a narrow range of tasks. These systems excel in their designated area, such as image recognition, language translation, or playing chess, but they do not possess the ability to generalize their knowledge or apply it to different, unrelated tasks. For example, a narrow AI that can diagnose medical conditions based on patient data cannot automatically perform tasks like driving a car or composing music. This lack of generalization is what distinguishes narrow AI from more advanced forms, such as General AI, which aims to replicate human-like cognitive abilities across various tasks. Thus, identifying this characteristic as the defining trait of narrow AI solidifies its place as the correct answer.
