# Evaluating and Comparing LLM Outputs for Your AI Application Here's a practical framework based on current best practices: ## 1. Choose Your Evaluation Method(s) There are three main approaches, each suited to different criteria: - **Code-based/deterministic evaluators**: Use for anything rule-based. As one source puts it, "if you could write a unit test for it, write a code evaluator. Save

Here's a practical breakdown for building an enterprise RAG pipeline in 2026, organized by decision point: ## 1. Buy vs. Build (the first real decision) Before picking individual tools, decide whether you're assembling a stack yourself or buying an integrated platform. The data on this is fairly stark: stitching a vector database, an embedding service, a reranker, a chunking pipeline, a connecto

There's no single universal "best" framework — the right choice depends on your architecture needs (stateful agents vs. RAG vs. multi-agent teams vs. enterprise governance), but a clear consensus has emerged in 2026 around a few leaders for different production scenarios. ## For stateful, production-grade agents: LangGraph LangGraph is the orchestration runtime most enterprise agent teams converg
