Jev Hack/Demo Night | Birds of a Feather

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 did too: Simple Jev - our open-source, open-weight implementation. Now we want to bring those people together and see what the wider Jev ecosystem is becoming. 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 demos Original Jev variants and real-world applications Honest breakdowns of what worked and what broke Lessons about latency, cost, confidence, training, and implementation Good food (dumpling bar), drinks, and plenty of time to meet other builders An 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.
