• Open Source Worth Watching Right Now (1) AI Agents and LLM Tooling

  The LLM application stack has split into layers: inference servers, orchestration, gateways, agents, and RAG. This post introduces 12 open source projects that are actually used at each layer, grouped by role rather than

• Embeddings and Rerankers: What Actually Matters in RAG

  What decides your embedding model in a RAG build is not a leaderboard rank but dimensionality, maximum input length, prefix conventions, multilingual coverage, and the division of labor with a reranker. This post lays ou

• Building an Internal Knowledge Base on an LLM — Permission-Aware Retrieval, Freshness, and the Eval Set You Need Before Launch

  The account Cerebras published on July 15, 2026 of how they built their internal knowledge base exposes the internals of a system fielding more than 15,000 queries a day from humans, automation, and agents alike. But the

• LLM API Cost Optimization — Break-Even Math for Output Tokens, Prompt Caching and Routing

  Cutting an LLM API bill in half is arithmetic, not intuition. Because output tokens cost several times what input tokens cost, the biggest lever is almost always controlling output length, with prompt caching next. This

• When RAG Answers the Wrong Thing — a Debugging Procedure That Separates Retrieval Failure from Generation Failure

  When RAG returns a wrong answer, most teams start by fixing the prompt, but the majority of real causes sit in the retrieval stage. This post starts with the single experiment — hand the model the gold chunk directly — t

• RAG · Fine-Tuning · Long-Context — Which One for My Problem: What the Papers Actually Measured, and What No One Measured

  It's the most common question in LLM architecture, yet most answers are decision trees with no sources. This post answers only with what has been measured. That fine-tuning fails at injecting new knowledge has been measu

• Graph RAG, Explained: What It Is and When It Earns Its Cost

  The standard RAG recipe — chunk, embed, retrieve top-k — works when the answer sits inside a single chunk, but it stalls structurally on multi-hop questions and on global sensemaking questions that span the whole corpus

• Production RAG Patterns — Why Naive RAG Fails and the Techniques That Actually Help

  A demo RAG system takes half a day to build, but the place it quietly breaks in production is almost always retrieval, not generation. This reference walks through chunking, embeddings and hybrid search (BM25 + vector),
