The amount of chat text an AI can read at one time.
A context window is the AI’s kitchen counter. Bigger counter, more notes and pizza boxes fit.
It sets how much earlier chat the AI can use. When it fills up, older text may get pushed out.
Token
A context window size is usually measured by how many tokens fit inside.
LLM
An LLM can only answer from information inside its context window.
Prompt
A longer prompt takes up more space in the context window.
