@jam.with.ai: Most RAG systems are slow because they dump everything into the context window. More input tokens = higher cost, higher latency, more hallucinations. Here’s how to fix it: 1. Pre-filter → Route queries to the right document set before searching 2. Semantic search → Use ANN techniques like HNSW for fast, relevant retrieval 3. Post-filter → Re-rank by freshness and verification before passing to the LLM Less context. Lower cost. Faster response. Better answers. #rag #llm #vector #study
