Why Longer Prompts Slow Down LLMs and How a Three‑Step Prompt Decay Audit Restores Performance

The article explains how overly long prompts dilute a large‑model’s attention, causing slower responses and contradictory outputs, and introduces a three‑step prompt‑decay audit—density measurement, slimming, and versioned output—that cuts response time from 1.8 s to 0.6 s, triples logical density, and reduces hallucinations by 60 %.
