Technical Architecture & Best Practices
**AI Model Selection**: Choose models based on use case: GPT-4 for complex reasoning ($0.03 per 1K tokens), Claude for long context and safety ($0.015 per 1K tokens), open-source models (Llama, Mistral) for cost savings when self-hosted. Use model routing: simple queries → cheap models, complex queries → expensive models (reduce costs 60%). Implement fallback chains: try fast model first, escalate to powerful model if needed.
**Prompt Engineering**: Design effective prompts with clear instructions, examples (few-shot learning), and structured output formats. Use system prompts for consistent behavior. Implement prompt templates with variables. Version control prompts like code. A/B test prompts measuring quality and cost. Use chain-of-thought prompting for complex reasoning (Let's think step by step). Implement prompt caching for repeated patterns (reduce API calls 40%).
**Vector Databases**: Use vector databases (Pinecone, Weaviate, Chroma) for semantic search and RAG (Retrieval Augmented Generation). Convert text to embeddings using OpenAI ada-002 ($0.0001 per 1K tokens) or open-source models. Store embeddings in vector DB with metadata. Query using similarity search (cosine similarity, dot product). Implement hybrid search combining vector and keyword search for best results. Use chunking strategies: split documents into 512-1000 token chunks with overlap.
**RAG Implementation**: Build Retrieval Augmented Generation to ground AI in your data. Steps: 1) User query → 2) Convert to embedding → 3) Vector search finds relevant documents → 4) Inject documents into prompt context → 5) AI generates answer using retrieved knowledge. Prevents hallucinations by providing factual sources. Enables AI to answer questions about private data not in training set. Use reranking (Cohere, cross-encoders) to improve retrieval accuracy 30%.

**Responsible AI Development**: Implement content filtering preventing harmful outputs. Use safety-tuned models (Claude, GPT-4 with safety settings). Test for biases across demographics. Provide human oversight for high-stakes decisions. Include disclaimers about AI limitations. Enable user feedback to flag issues. Audit model outputs regularly. Follow AI ethics guidelines (transparency, fairness, accountability).
**Cost Optimization**: Cache repeated queries (reduce API calls 40%). Use smaller models for simple tasks (GPT-3.5 vs GPT-4 costs 10x less). Batch API requests when possible. Implement request throttling preventing abuse. Monitor per-user costs setting limits. Use open-source models for high-volume use cases. Self-host for >10M requests monthly (break-even point). Stream responses reducing perceived latency and timeout costs.
**Prompt Engineering**: Start with clear, specific instructions. Provide examples (few-shot learning improves accuracy 30%). Use structured output formats (JSON, XML). Implement system prompts for consistent behavior. Version control prompts treating as code. A/B test prompts measuring quality and cost. Use prompt chaining for complex tasks (break into steps). Implement retry logic with refined prompts if output invalid.
**Data Privacy**: Never send PII to AI APIs without consent and necessity. Use data anonymization removing names, emails, phone numbers. Prefer models with data privacy guarantees (Azure OpenAI, Claude with data retention opt-out). Implement end-to-end encryption for data in transit. Store sensitive data locally, send only non-sensitive context to AI. Follow GDPR, HIPAA, SOC 2 requirements. Audit data handling quarterly.
