The AI Stack: A Practical Guide to Building Your Own Intelligent Applications

This guide provides a comprehensive overview of building an AI stack for practical applications, covering the essential layers from data retrieval to model integration and beyond. Here's a summary of key points and actionable steps:

Key Points

1. Understanding the Layers:

   • Data Retrieval: Use vector databases like Qdrant or Pinecone to store embeddings.
   • Model Integration: Choose between cloud APIs (e.g., Anthropic, Cohere) for large models or local models (e.g., LLaMA, GPT-NeoX).
   • Orchestration: Combine data retrieval and model integration using frameworks like LangChain.

2. Building an AI Stack:

   • Start with a simple task: summarize meeting notes, generate SQL queries from natural language, or classify support tickets.
   • Use RAG (Retrieval-Augmented Generation) to ground the model in your specific data.
   • Implement logging and monitoring for continuous improvement.

3. Navigating Pitfalls:

   • Cost Management: Cache common queries, set strict token limits, and use tiered models.
   • Latency: Optimize chunking, use quantized models, and implement streaming responses.
