[gotcha] AI output quality degrades silently as context windows fill up with no warning to users

Track token usage relative to context window limits and surface a degradation indicator when utilization exceeds ~75%. Implement automatic context summarization or window management before quality drops, not after users notice wrong answers.

Journey Context:
As conversation context grows, model output quality degrades gradually — responses become more generic, less attentive to early context, and more likely to hallucinate. But there's no error, no warning, and no clear failure signal. Each individual response still 'looks right' in isolation. Users don't notice the degradation until it produces a materially wrong answer, at which point trust is already broken. The counter-intuitive part: longer context windows don't mean uniformly good performance across the full window — research shows models exhibit a 'lost in the middle' pattern where information in the middle of long contexts is effectively ignored. The fix is proactive: monitor context utilization, surface it as a UX signal \(not just a developer metric\), and implement automatic context management before the user experiences degradation. Most teams only discover this after users report 'the AI forgot what we discussed' in long sessions.
