general ai

terms you'll run into using ai, not just vibecoding

definitions

prompt

/prɑmpt/
definition

the text you give an ai model to tell it what you want. it can be a question, an instruction, examples, or all of them at once.

plain

what you type into the ai. the clearer and more specific you are, the better what comes back.

in context

"tighten the prompt." → say more exactly what you want, and what you don't, so the ai stops guessing.

token

/ˈtoʊkən/
definition

the unit an ai model reads and writes in. a token is a chunk of text, often a few characters or part of a word, not a whole word.

plain

ai doesn't count words, it counts tokens, little pieces of words. usage limits and pricing are measured in them.

in context

"that's about 1,000 tokens." → roughly 750 words of text going into or out of the model.

context window

/ˈkɑntɛkst ˈwɪndoʊ/
definition

the most text a model can take in at once, measured in tokens, counting both your input and its reply.

plain

the model's short-term memory. fit your stuff inside it and the model sees all of it; go over and the oldest parts fall off.

in context

"it has a 200k context window." → it can keep around 150,000 words in view at one time.

hallucination

/həˌluːsəˈneɪʃən/
definition

when a model produces information that is false or made up while presenting it confidently as fact.

plain

the ai making something up and sounding sure about it. it isn't lying, it's filling a gap with plausible-sounding text.

in context

"double-check it, models hallucinate citations." → it might invent sources, quotes, or numbers that look real but aren't.
