Practical RAG for images. CLIP embedding + OCR improves accuracy 72%->91%. Extract figure metadata (title, caption, chart type) as JSON. Cohere Rerank improves top-5 by 18%. 10M images on single-node Milvus at 95% recall, 50ms p99 latency. Bottleneck is metadata extraction quality, not vector search performance.
