No slides. Demo the thing.
We focus on demos, code, and technical insight. No sales pitches, no generic AI panels. Working systems set the agenda.
Innovate. Share what broke.
Bring side projects, unfinished systems, architecture notes, trade-offs, and failure modes. The room is built for candid technical work.
Local rooms. Global signal.
Each city protects the room locally while contributing to a shared global standard for serious AI builders.
Standard
Working code beats hype.
Demos, traces, systems, and scars carry more weight than predictions.
Belief
Practitioners, not spectators.
The future of AI is built by people close enough to the work to show it.
Room Rule
Demos over decks.
If it matters, bring the thing and show how it behaves.
Like the Homebrew Computer Club, AI Tinkerers is built around small rooms where practitioners compare notes before the path is obvious.
