There are plenty of new terms relating to artificial intelligence, but a strange one has been "AI" itself. Whereas for the past 75 years, everything in the computer world has been a system (computer system, information system, operating system, etc.), AI people initially avoided the word "system" like the plague. An AI system, the combination of hardware and software that produces results, has often been called simply an "AI." For example, "an AI can do this... an AI can do that..." has been common phraseology. It sounds a bit short, nevertheless, people say "the computer does this" when in fact it is always "the computer system" that is doing the work.
By the mid-2020s, the term "AI system" began to emerge (see
AI agent). However, "an AI" will likely be synonymous with "an AI system" for a long time. More terms describing AI are AGI, Super AI, AI hard and AI complete (see
AGI,
AI complete and
technology singularity). For an AI overview, see
AI in a nutshell. For general AI terms, see
AI training vs. inference,
AI emergent properties,
AI hallucination,
large language model,
neural network and
deep learning.
