Test Chicago Driesnote repo with cheaper models
## Problem/motivation
The Chicago Driesnote demo videos were recorded with Open AI for Vector DB and Opus 4.6 for everything else. Opus 4.6 is expensive. It can cost $1 to $2 USD to create a page.
We want to see if cheaper models can produce okay results.
## Solution
Test with smaller/cheaper models and post results.
## Tasks
- [x] Set up demo environment
- [x] Test with 2 or 3 cheaper/smaller models
- [x] Post results
