Wikipedia has that this is not the common-use definition of “acronym”, though some argue for it. In the common-use sense, an initialism is just one type of acronym.
For some, an initialism or alphabetism, connotes this general meaning, and an acronym is a subset with a narrower definition: an acronym is pronounced as a word rather than as a sequence of letters. In this sense, NASA /ˈnæsə/ is an acronym but USA /juːɛsˈeɪ/ is not.
The broader sense of acronym, ignoring pronunciation, is its original meaning and in common use. Dictionary and style-guide editors dispute whether the term acronym can be legitimately applied to abbreviations which are not pronounced as words, and they do not agree on acronym spacing, casing, and punctuation.
For info, AI is an initialism, not an acronym. Acronyms are pronounced like words (NASA, NATO), whereas initialisms are just the letters (AI, FBI).
