Prompting glossary
Context window
How much text the AI can hold at once.
What it means
The context window is the amount of text a model can keep in view during one conversation, including your instructions and everything it has already written. When a long chat starts forgetting earlier rules, the important details have slid out of view and need restating.
How to use this in practice
Knowing the word is the easy half. The useful half is writing the instruction so the AI does not have to guess: say who it should act as, give it the background it cannot know, state the outcome you want, set the limits, and name the format the answer should come back in. That is the same structure behind every template in the free prompt library.
