Retrieval-Augmented Generation is the most practical pattern for building AI systems that work with your data.
Move past simple prompting into structured techniques like chain-of-thought, few-shot, and tool calling.
AI agents are autonomous systems that use LLMs to reason, plan, and take actions. Here is how to build them.
Tracing, metrics, and monitoring are not optional for production AI systems. Here is how to set up observability from day one.
MCP is emerging as the standard way for AI models to interact with external tools and data sources.
