Every time a new Claude model lands, we get the community in a room to build with it. Fable 5.1 ran in Brisbane and Sydney on back-to-back nights in September, then Opus 5.5 took Brisbane in October. Hands on keyboards, no long talks.
in Claude API credits for every attendee, to build on the night and keep going after. Build solo or in a small team, demo it, and the judges pick the winner.
Same idea every time: a new model, a room full of builders and one night to see what it can do.
The same three tracks run at every Build Day.
Something surprising, beautiful or fun that you couldn't have made this good, this fast, before.
Something the previous model couldn't handle. See how far the new one gets.
Something that solves a real problem in your life.
Never been to one? Here's how it feels on the night. Beginners and seasoned builders both belong in the room.
The night opens with the new model on screen, shown by people who know it. You see what it can do before you try it.
Most of the time is build time. No long talks, no slides to sit through. Just you, the model and a problem.
Mentors walk the room. Wayne Hoggett from Pluralsight in Brisbane, Dominik Fretz in Sydney. Stuck is fine, staying stuck isn't.
Come solo and join a team, or bring your own. Plenty of people meet their next collaborator at one of these.
Everyone who builds gets to demo. The judges pick the winner on the night, and the room gets to see what's possible.
A new model is a big moment. We mark it together, with good food, good people and a lot of happy noise.
A packed room, a lot of pizza and three hours of building. Here's how it looked.
The judges choose a winner at the end of every Build Day. As each night's winning builds are written up, they land on this page with a link to try them. Until then, each event page has the details.
Register interest and you'll hear first, with time to grab a spot before they go.
