Frequently Asked Questions
Which embedding model should I use (OpenAI, BGE, Cohere, E5)?
▼
It depends on 4 factors: (1) Quality: OpenAI text-embedding-3-large (best quality, 3072 dims, $0.00013/1K tokens) OR Cohere Embed v3 (multilingual, 100+ languages, $0.0001/1K). For self-hosted: BGE-large-en-v1.5 (SOTA quality, $0 API fees) OR E5-large-v2 (Microsoft, excellent retrieval). (2) Cost: High volume → Self-hosted (BGE, E5, all-MiniLM, $0 API fees). Low volume → Cloud APIs (OpenAI, Cohere). (3) Languages: Multilingual → Cohere Embed v3 (100+ languages). English only → BGE or OpenAI. (4) Privacy: HIPAA/GDPR → Self-hosted only (BGE, E5). We often recommend HYBRID: Self-hosted BGE for bulk embedding (millions of docs, $0 cost) + OpenAI for query embedding (better quality, $0.001/query). Best of both worlds!
Which vector database should I choose (ChromaDB, Qdrant, Milvus, Pinecone)?
▼
Depends on scale and needs: (1) ChromaDB: <10K docs, POC/MVP, embedded (Python), simple setup. Perfect for testing RAG. Free, self-hosted. (2) Qdrant: 10K-1M docs, production, hybrid search (semantic + keyword), filters, metadata. Self-hosted or cloud. Enterprise-ready. (3) Milvus: >1M docs, billions of vectors, distributed cluster, horizontal scaling. For massive scale (Google-size). Self-hosted on Kubernetes. (4) Pinecone: Managed cloud, no ops, fastest setup, pay-as-you-go ($0.096/hour). Great if you don't want to manage infrastructure. (5) pgvector (Postgres): Use existing Postgres, simple, reliable, <100K docs. Good for teams already on Postgres. We recommend: Start with ChromaDB (POC) → Qdrant (production) → Milvus (massive scale). Or Pinecone if you want managed cloud.
How much does RAG cost vs using full context with LLMs?
▼
MASSIVE savings! Sending full docs to LLM: Example: 100-page PDF = 50K tokens. GPT-4 input: $0.01/1K tokens = $0.50 per query. 1000 queries/day = $500/day = $15K/month = $180K/year. RAG approach: (1) Embeddings (one-time): 50K tokens × $0.00013 (OpenAI) = $0.0065 per doc. Or $0 if self-hosted BGE. (2) Vector search: Free (self-hosted) or $0.096/hour (Pinecone) = $70/month. (3) LLM with RAG (only relevant chunks): 2K tokens per query (10x smaller!) × $0.01 = $0.02 per query. 1000 queries/day = $20/day = $600/month = $7.2K/year. Savings: $180K - $7.2K = $172.8K saved per year (96% reduction!). Even with cloud vector DB: $7.2K + $0.84K = $8K/year vs $180K = 95% savings. ROI is insane!
What is chunking and why does it matter?
▼
Chunking = breaking documents into smaller pieces for embedding. CRITICAL for RAG accuracy! (1) Why chunk? LLMs have context limits. Embeddings work best on 100-500 tokens. Need to retrieve most relevant sections, not entire docs. (2) Chunking strategies: Character-based (simple, 512 chars, overlapping 50). Recursive (smart, respects paragraphs/sentences). Semantic (AI-based, breaks at meaning changes). Document-specific (PDFs: by section, code: by function, tables: by row). (3) Overlap: Add 10-20% overlap between chunks to preserve context. Example: Chunk 1: tokens 0-512, Chunk 2: tokens 450-962 (overlap 450-512). (4) Metadata: Extract title, section, page number, date per chunk for filtering. Bad chunking → poor retrieval → wrong answers. Good chunking → 95%+ accuracy. We test 5-10 chunking strategies and pick the best for YOUR data!
How accurate is RAG compared to fine-tuning or prompt engineering?
▼
RAG vs Fine-tuning vs Prompts: (1) RAG: 95-99% factual accuracy (grounded in docs), works with latest data (real-time updates), no retraining needed, cost-effective ($8K-$55K one-time + low hosting). Best for: Q&A, search, chatbots with company data. (2) Fine-tuning: 90-95% accuracy (can still hallucinate), requires labeled data (1000s of examples), expensive ($20K-$100K), needs retraining for updates. Best for: Specific tasks (classification, style), proprietary workflows. (3) Prompt engineering: 70-85% accuracy (limited by context window), manual prompt crafting, limited knowledge (only what fits in prompt). Best for: Simple tasks, prototypes, low-volume. RAG advantages: Always accurate (citations to source docs), scales to billions of docs, stays current (sync with data sources), cost-effective at scale. We often COMBINE: RAG for knowledge retrieval + fine-tuned LLM for domain reasoning. Example: Medical RAG (retrieves papers) + fine-tuned medical LLM (diagnosis reasoning) = 99% accuracy!
Can RAG handle real-time data updates?
▼
YES! Multiple approaches: (1) Incremental indexing: New/updated docs → embed → upsert to vector DB (seconds to minutes). Example: New support ticket arrives → embed → add to Qdrant → instantly searchable. (2) Scheduled batch updates: Nightly/hourly sync with data sources (Confluence, databases). Check for changed docs, re-embed, update vector DB. (3) Webhook-based: Data source sends webhook on change → trigger embedding pipeline → update index. Example: Notion page updated → webhook → re-embed → update ChromaDB. (4) Streaming updates: Real-time data streams (Kafka, Kinesis) → continuous embedding → vector DB. For high-frequency updates (stock prices, news). (5) TTL (Time-to-Live): Set expiration on embeddings, auto-refresh stale data. Latency: Incremental: seconds. Batch: minutes to hours (depending on frequency). Streaming: real-time. We implement: Automatic sync jobs + webhook listeners + manual refresh API. Your RAG always has latest data, no stale answers!
