|
|
| ## Overview |
|
|
| Build Small is a hackathon that pushes back against the trend of ever-larger AI models. Armed with at most **32 billion parameters**, participants solve a real problem for someone they know โ or build something delightfully weird. The app must be a **Gradio app hosted as a Hugging Face Space**. No giant LLMs. No B2B SaaS sprawl. Just small models, big ideas, and good vibes. |
|

|
|
| ## Tracks |
|
|
| ### ๐ก Chapter One โ Backyard AI |
|
|
| Build something useful for a **real person you know**: a neighbour, a parent, a small-business owner. The problem must be specific, the person must actually use the app, and the solution must honestly fit the small-model constraint. |
|
|
| **Judging criteria:** |
| - Problem is specific and real |
| - The person actually used it |
| - Honest fit between problem and the small-model constraint |
| - Polish of the Gradio app |
|

|
|
| ### ๐ Chapter Two โ An Adventure in Thousand Token Wood |
|
|
| Build something **delightful that wouldn't exist without AI** โ a toy, a tiny game, a strange interactive story, an art experiment. The AI should be doing the fun thing, not just assisting with the build. Strange is good. Joyful is the bar. |
|
|
| **Judging criteria:** |
| - Genuinely delightful (would you show a friend?) |
| - AI is load-bearing for the experience |
| - Originality of concept |
| - Polish of the Gradio app |

| ## Strategy Notes |
|
|
| - **Maximize merit badges**: Combining badges like *Off the Grid* + *Llama Champion* + *Off-Brand* targets three separate bonus awards on top of the main track prize. |
| - **Tiny Titan opportunity**: A genuinely excellent app at โค 4B parameters competes for both a main track prize *and* the $1,500 Tiny Titan special award. |
| - **`gr.Server` is underexplored**: The Off-Brand Award ($1,500) and the merit badge reward custom UIs โ this is a differentiator for anyone with frontend skills. |
| - **Document everything**: The *Field Notes* badge and *Best Demo* award reward teams that ship thoughtful write-ups and polished videos alongside their app. |
