LLM Showdown: ChatGPT vs Claude vs Gemini vs Local Models
Join us for a practical, beginner-friendly guide to choosing the right large language model. Weโll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability.
Youโll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Data & Analytics Wednesday - Mapping and Dashboards
**Total Eclipse of the Chart: School Redistricting Dashboards**
In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide โwhat-ifโ analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these.
While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics.
