# Build Small Hackathon

Source: https://huggingface.co/build-small-hackathon

## Basic Details
- **Host:** Gradio & Hugging Face
- **Registration:** May 7 – June 3, 2026 (CLOSED)
- **Hack Window:** June 5–15, 2026 (ACTIVE)
- **Submission Deadline:** June 15, 2026

## Theme
Build AI applications using **small models (≤32B parameters)** to solve real problems or create delightful experiences. Emphasis on "thinking small" rather than building large-scale B2B SaaS.

---

## Tracks

### Track 1: Backyard AI
Solve a real problem for someone you know (neighbor, parent, small-business owner). The person must actually use it.

Judging:
- Problem is specific and real
- Person actually used it
- Honest fit between problem and small-model constraint
- Polish of the Gradio app

Prizes: 1st $4K, 2nd $2.5K, 3rd $1.5K, 4th $1K

### Track 2: Thousand Token Wood
Build something delightful that wouldn't exist without AI — toys, games, interactive stories, art experiments. AI must be load-bearing.

Judging:
- Genuinely delightful
- AI is essential (not just a helper)
- Originality of concept
- Polish of the Gradio app

Prizes: 1st $4K, 2nd $2.5K, 3rd $1.5K, 4th $1K
