AI Tinkerers Chicago: October Meetup ft. Antithesis

The Chicago chapter of AI Tinkerers, the global curated community of engineers and technical founders shipping with LLMs and generative AI. October's edition is hosted at Drive Capital's Fulton Market office and features Antithesis (the autonomous testing / world-simulation startup) on engineering tradeoffs, plus lightning demos and a science fair where attendees show what they're actually building. The site is strict about who gets in: no pitches, no vendor talks, just builders. If you're writing production LLM code in Chicago, this is the room.
