About this hackathon
There’s a reason Jev is going incredibly viral.
After Jev's release, builders began experimenting with their own models, applications, and variations on the idea.
We’re looking for everything from products built with Jev to entirely new Jev variants: different base models, specialized domains, new decision formats, creative training approaches, and ideas we haven’t imagined yet.
What to expect
Five to six short, live demosOriginal Jev variants and real-world applicationsHonest breakdowns of what worked and what brokeLessons about latency, cost, confidence, training, and implementationGood food (dumpling bar), drinks, and plenty of time to meet other buildersAn optional open-demo period after the talks
Schedule
6:30 p.m. — Doors, dinner, and demos7:00 p.m. — Welcome and “What is Jev?”7:10 p.m. — Community Jev and variant lightning demos8:15 p.m. — Builder Q&A8:30 p.m. onward — Drinks, networking, and open demos
This is for engineers, founders, researchers, agent builders, model tinkerers, and anyone curious about machine-native AI decisions.
Built something with Jev-or created a Jev variant of your own? Add your demo link when you register. After seeing what happened with Simple Jev, we can’t wait to see what everyone builds next.
