Labs release larger and larger models that do more of the things that make us feel human — writing, drawing, speaking, coding. No wonder more than half of us think the risks of AI outweigh the benefits.
We're sponsoring a hackathon to take things back to how they felt in 2021 — when models were small enough to tinker with, and the vibe was fun and hopeful about how this technology could improve our lives. This hackathon is different. Rather than using a giant LLM to ship yet another B2B SaaS, we want you to think small. Armed with only 32 billion parameters, solve a problem someone you know is facing — or build something whimsical.
❋ Two Tracks · Pick your trail Choose your own adventure. Chapter One 🏡 Backyard AI Solve a real problem for someone you actually know. Pick a person — a neighbor, a parent, a small-business owner on your street — and build something that makes their day measurably better.
Judged on Problem is specific and real The person actually used it Honest fit between problem and the small-model constraint Polish of the Gradio app Chapter Two 🍄 An Adventure in Thousand Token Wood Build something delightful that wouldn't exist without AI. Wander somewhere weirder. A toy, a tiny game, a strange interactive story, an art experiment that surprises you. The AI should be doing the fun thing — not just helping you build it. Strange is good. Joyful is the bar.
Judged on Genuinely delightful (would you show a friend?) AI is load-bearing for the experience Originality of concept Polish of the Gradio app ❋ The Constraints — Three rules of the trail Pack light. 1 Small Models Only Total parameters must be ≤ 32 billion. The model fits on a laptop. So should your ambition.
2 Built on Gradio Your app must be a Gradio app, hosted as a Hugging Face Space. That's the canvas.
3 Show, Don't Tell A short demo video and a social-media post are part of the submission. Make it sing.
❋ Bonus Quests · Six earnable merit badges Stack 'em on your sash. None required. Each one grants extra points for your submission. Hover a patch to see it lift.
