Data Freshness Rot: The Silent Killer of Production RAG Systems Most ML engineers I know are obsessed with model quality. Better evals, better prompts, better fine-tuning. And honestly, I get it. Model quality matters. But after watching enough production RAG systems quietly degrade over months, I’m convinced the real killer isn’t the model at all….
