Artificial intelligence (AI) is the ability of computer systems to perform tasks that normally require human intelligence, such as learning, reasoning, recognizing patterns, understanding language, and making decisions. In more technical terms, it is a field of computer science that builds algorithms and models enabling machines to perceive their environment, infer from data, and choose actions that achieve specified goals. AI today mostly appears as “narrow” systems specialized in specific tasks—like translation, recommendation, or image recognition—rather than human‑level general intelligence across all domains.ibm+4
