Create a horizontal system-architecture diagram of a retrieval-augmented-generation (RAG) LLM agent with three connected lanes plus a surrounding agent loop. Top-left ingestion lane: a stack of documents flows into a "Chunker (512 tokens, 50 overlap)" box, then an "Embedding Model (text-3-large, 1536-d)" box, then a cylinder labeled "Vector DB (1.2M chunks)". Center query lane: "User Query" embedded, arrow to "Top-k Similarity Search (k=5, cosine)" reading from the vector DB, then "Prompt Template (context + question)" feeding an "LLM" box that outputs a "Grounded Answer with citations [1][2]". Wrap these in an agent loop with rounded nodes: Planner, Tool Calling (web search, calculator, code), and Short-term / Long-term Memory, joined by curved feedback arrows. Add a small inset bar chart titled "Answer Accuracy" comparing No-RAG 61% vs RAG 89%, and latency tags reading "retrieve 40 ms" and "generate 1.2 s". Use a clean technical style, labeled arrows, monospace component captions, soft blue and teal accents on white.
