When an AI model seems to "get worse" over time from the user's perspective — usually after a safety tuning update. Whether it's real or imagined is debated constantly online.

"Claude feels worse this month — is it model rot?"
Origin: AI / developer industry term, 2023–2025.
For parents

'Model rot' refers to AI language models degrading over time — either because the model is retrained on AI-generated content (a known problem), or because users perceive a deployed model has become worse since launch. If your teen talks about model rot, they are engaging with AI-quality debates. Useful media-literacy vocabulary; underlines why critical evaluation of AI output matters.

For ESL learners

'Model rot' is informal AI/ML terminology for perceived or measured degradation in a language model's performance over time. Two senses: (1) technical — degradation from retraining on AI-generated content ('model collapse'); (2) anecdotal — users' perception that a deployed model has worsened since launch. Register: informal, AI industry discussion. In academic writing use 'model degradation' or 'model collapse' for technical contexts. A common learner mistake is to assume model rot is always documented technical fact; the perception sense is widely disputed.

Why is this section here?

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
