Challenge Overview

Theme: Ghost in the Machine

Objective: Build a project powered by open-source AI or open-weight models that explores spooky experiences, Halloween, Día de los Muertos, remembrance, or forgotten technology.

The project must use open AI technology as a core part of its functionality, rather than simply connecting to a closed AI API.

Project Requirements

The project may involve:

Running an open-weight AI model locally.
Using open-source AI frameworks or agent tools.
Running AI inference without an internet connection.
Building applications that protect personal data through local processing.
Customizing, fine-tuning, or switching models.
Reviving abandoned open-source projects or forgotten internet history.

Suggested Project Ideas

Phantom Terminal: A haunted terminal that generates eerie commentary about commands and computer activity.
Echoes — Family Memory Keeper: A private application that preserves family stories, recordings, photographs, and memories.
Offline Séance Chatbot: A chatbot inspired by an old programming language or historical technology.
Ghost Story Generator: An AI application that turns fictional smart-home activity logs into spooky stories.
Ghost of Code: An application that revives forgotten programming languages or abandoned open-source projects.

Important Considerations

Build a functional prototype rather than submitting only a concept.
Ensure the open AI component is essential to the application.
Test offline functionality before claiming the project works without internet access.
Verify the chosen model's license and hardware requirements.
Include clear setup instructions and a demonstration.
Explain honestly where open AI provides advantages over closed alternatives.

Official Submission

Publish the project write-up on DEV using the challenge's submission template.
