Deduplication in RAG systems cuts context size without quality loss

A new preprint details an empirical analysis of byte-exact deduplication in Retrieval-Augmented Generation (RAG) systems. The study found significant context reduction across academic, enterprise, and conversational AI use cases, with an 80.34% reduction in multi-turn conversations. Crucially, this deduplication process introduced no measurable quality degradation, as validated by a cross-vendor evaluation involving Google Gemini, Anthropic Claude, Meta Llama, and OpenAI GPT models, all meeting strict quality thresholds.
