A Developer’s Guide to Running LLMs Locally- Alan Barber

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Tensors, Tokens & Too Much VRAM: A Developer's Guide to Running LLMs Locally* What actually happens when you send a prompt to an LLM? What are tokens, tensors, attention, quantization, and all those mysterious gigabytes of VRAM doing? And why does your GPU suddenly become the most important piece of hardware in the room? This talk takes a developer-friendly tour through the fundamentals of modern LLMs. We’ll try to demystify concepts like context windows, model quantization, and inference performance without requiring a PhD in linear algebra. Then we'll take those concepts out of the textbook and into the real world, looking at tools such as Ollama, LM Studio, and vLLM and what it takes to run useful models on your own hardware. By the end, you'll have a mental model for what an LLM is actually doing, how local inference works, and why sometimes the answer to "How much VRAM do I need?" is apparently "all of it." **YouTube Link** TBD

September Childfree Connection Night!!

Haunted Hike Through Walhalla Ravine

**Dare to Enter Walhalla Ravine?** There are places in Columbus where the city seems to disappear. Walk far enough into **Walhalla Ravine**, beneath the old trees and steep wooded hillsides, and the traffic grows distant. The houses above become harder to see. The path narrows, shadows gather beneath the canopy, and suddenly it becomes very easy to understand why people have been telling strange stories about this place for generations. Stories of **murder, apparitions beneath the bridge, unexplained lights, and the thing once whispered about as the Walhalla Witch** have become part of Clintonville folklore. Most have been embellished over the years. Some can be debunked. Others are simply stories with no way left to determine where the truth ended and the legend began. We’re going in anyway. **Disclaimer:** This is **NOT a scripted ghost tour**, and **I’m NOT a professional storyteller.** **Think of it more as a group adventure**: we’ll hike, explore, discuss the legends and history, and see some of the locations that inspired the stories for ourselves. Come prepared to walk, explore, and get a little off the beaten path. **Click Here: [Read about the ghosts and legends of Walhalla Ravine](https://thearcanefoundry.com/daclaud-lee/haunted-columbus/walhalla-ravine-the-ghosts-witch-legends-of-columbus-ohio/?utm_source=chatgpt.com)** This is a FREE event. Tips are appreciated (but never required) for showing you the hidden paths and lesser-known parts of the ravine. Just a reminder: **if you RSVP, please make every effort to attend.** **OPTIONAL:** Afterward, anyone who wants to keep the evening going can join us nearby for drinks at Derive Brewing Company or pizza and drinks at Hounddog’s.

Building a RAG Assistant with Azure AI Search + Azure OpenAI

**From React Docs to AI Answers: Building a RAG Assistant with Azure AI Search + Azure OpenAI** In this session, I’ll walk through how to build an AI-powered documentation assistant for a modern React web product using Azure AI Search, Azure OpenAI, and a Next.js frontend. The talk will focus on a practical use case: taking documentation, component examples, and product content, indexing it for retrieval, and using that context to generate grounded answers inside a web app. I’ll cover the architecture, data flow, prompt design, chunking strategy, deployment approach, and common mistakes developers run into when adding AI to real web products. The session will include code examples and a demo-style walkthrough showing how a developer could turn static docs or internal knowledge into an interactive AI assistant. Attendees will leave with a practical blueprint for building their own RAG-powered web experience on Azure without turning it into an overcomplicated cloud architecture.
