The Midnight House: a ghost you talk to through a spirit board

Описание и применение

Игра «Midnight House» демонстрирует, как открытые модели позволяют создавать интерактивного призрака, чьи ответы отражают реальные вероятности токенов, показывая игроку неуверенность модели и предотвращая утечку скрытых секретов.

Задача

Create an interactive haunted‑house game where the ghost’s responses reflect real next‑token probabilities, exposing model uncertainty to the player.

Результат

The game demonstrates how open‑weight models enable transparent ghost interactions, revealing model uncertainty and preventing secret leaks, while providing a private, offline experience.

Рабочий процесс

• 1. Install dependencies and pull Gemma via Ollama. 2. Run FastAPI server with SSE endpoint. 3. Player explores rooms, unlocking facts. 4. Ghost’s prompt contains only unlocked facts. 5. Model streams tokens with probabilities; UI updates planchette speed and whispers. 6. Spoiler guard checks replies; blocked leaks are logged. 7. Progress stored in MongoDB or memory; Backboard provides cross‑session memory. 8. Deploy to Render; Browserbase smoke‑tests the live game.

Доказательства

The planchette doesn’t move on a random timer. It moves using the model’s real next-token probabilities.

Источник

If an endpoint doesn’t expose logprobs, the UI says so and uses a fixed-speed planchette.

Источник

A spoiler guard. If the model still blurts out a locked secret, a word-boundary check replaces the reply with I cannot say.
