Context window
A context window is the maximum amount of text a language model can consider at once when generating a reply.
The entries below are preserved in their original source language to avoid unreviewed machine translation.
In AI roleplay, the context window contains the system prompt, character card, persona, summaries, and recent messages. When it fills up, older details must be dropped, summarized, or retrieved another way.
Plain-language meaning
The model does not remember everything by default. It can only respond from the information placed in front of it for the next turn.
Most complaints about characters forgetting names, promises, locations, or earlier scenes trace back to context-window limits and weak memory design.
OnlyKin should explain context windows plainly so users understand why compact memory and structured cards matter.
