Design, Optimization, and Deployment of a Hybrid Agentic Retrieval-Augmented Generation (Agentic-RAG) Architecture
Abstract Traditional RAG pipelines usually work deterministically by using only static vector search[cite: 1]. Because of this, vocabulary mismatche…
Bedrock Guardrails Blocked My RAG Bot's Own Questions: Denied Topics and Contextual Grounding Tested
By Tim O. I am studying for the AWS Certified AI Practitioner exam, and I wanted something to build rather than another set of flashcards. The 2026…
Mind Discipline: Why Our AI Advisor Only Reads Hand-Crafted Contracts
In my first post, I wrote about why I spent my first week writing zero business logic and instead built rig - our lightweight, POSIX-compliant local…
Is Agent Memory Just RAG With Extra Steps? We Opened the Source Code to Find Out
Under every agent memory launch, the same comment appears: "so it's RAG with extra steps." Instead of arguing, we opened the shipping source of mem0…
LLMOps for RAG Systems — Production Checklist
Why the pipeline, not the model, is usually to blame If your LLM feature starts hallucinating or your inference bill doubles overnight, the model is…
Using SynapCores as a LlamaIndex Vector Store + Property Graph Store
Most LlamaIndex setups end up with two separate backends once you go beyond plain vector search: a vector store for VectorStoreIndex , and a separat…
Vector RAG: Why It’s Winning in Production
Source: https://pageindex.ai/blog/ocr Vector RAG: Why It’s Winning in Production In a world where LLMs are the new CPUs, the bottleneck isn’t the mo…
Your local RAG isn't slow — it re-reads every document on every question
A user opens a project with nine files in it, types the most obvious question anyone types at a document app — "what are these documents about?" — a…
From Pixels to Prescriptions: Building an AI Pharmacist with YOLOv10 and RAG
We’ve all been there: staring at a cluttered medicine cabinet, holding two different blister packs, and wondering, "Can I take these together?" In t…
Your RAG Demo Works Because Someone Picked the Documents
A RAG prototype takes an afternoon. Chunk some documents, embed them, stuff the top matches into a prompt, ship a chat box. It works. You demo it, e…
Your Documents, Chunked and Searchable: The Knowledge Base in ByteChef
TL;DR: A Knowledge Base in ByteChef is a managed RAG store: drop in documents (PDF, Markdown, Word, JSON, plain text - and scanned PDFs or images, t…
Architecting for Reliability: The Role of Message Brokers in Multi-Agent AI
When building Agent-to-Agent (A2A) systems, the biggest trap is treating AI agents like standard REST APIs. If your Orchestrator Agent synchronously…
My Agent Answers From 0.6% of Its Corpus and Reports It Like a Full Read
Originally published at ai.bedvibe.studio . My portfolio RAG agent holds 1,003 indexed chunks. A question retrieves six and answers. Six of 1,003 is…
I Built an MCP Memory Server Where Code, Not the Model, Decides What Gets Stored
There's a hole in almost every AI memory library, and once you see it you can't unsee it: the model that hallucinates is also the thing you've put i…
Three things I got wrong measuring my own cache

I Almost Shipped a RAG Assistant That Lied About APIs That Don't Exist
I wrote this on X a few weeks ago: I just had a very bad reminder as to the fact these LLMs are statistical parrots, I let it write code I normally…
Model Cascade: making LLM classification cheaper
Many LLM workloads are classification tasks. This can get expensive, and I believe it is going to become more and more important, especially with th…

A Developer's Checklist for Every RAG Lifecycle (Beyond Chunk-Embed-Search)
If your mental model of RAG is "chunk → embed → search → LLM," you're missing about 80% of what actually makes a RAG system production-ready. Here's…
483 tests passed, but Vestibule RAG framework wasn't installable — lessons from building with AI agents
I spent two months building Vestibule, an open-source Python framework for the boring layer of RAG ingestion — stable document IDs, a state ledger,…
ai agents vs automations: When to build an autonomous agent and when a simple workflow suffices
What's the difference? An AI agent is a loop-driven system that can decide which tool to call next, keep state across interactions, and adapt its be…
RAG vs MCP in AI Testing: Stop Treating Them as Competitors
If you are building AI-powered test automation, you may eventually run into this question: Should we use RAG or MCP? The question sounds reasonable,…

Local RAG starts with retrieval, not infrastructure
RAG projects have a way of collecting infrastructure before they collect evidence. A database gets provisioned. A vector store appears. Then Redis,…
