context rot

Context rot is the AI phenomenon where a long conversation degrades model performance because too much information is in the context window. Tech jargon. Not concerning. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.

Context rot is a 2024 AI-engineering term describing the degradation of language model performance as the context window fills with extensive or noisy content. Use in AI engineering writing. Formal equivalent: "context window degradation." Common non-native mistake: confusing with concept drift (training data shift). Context rot is a runtime, in-conversation phenomenon. Read or listen to the word in context several times before trying it yourself; the right register is harder to learn than the dictionary meaning.
