Dethrone: an Open-Source Card Game That Tests Jev, the Model That Outputs Decisions, Not Text
aaddrick · reddit · 2026-09-20
Developer aaddrick built Dethrone, a free open-source card game where TypeSafe's decision model Jev plays the king and players try to dethrone him. Key details:
- Jev returns probabilistic decisions in 700ms without writing text; all on-screen words are human-authored
- Each turn uses two calls: forecast consequences, then choose based on forecasts, since questions in one call are answered independently
- Wisdom stat sets odds between the king's wishes and advisor's knowledge; the model dies by its own predictions
- Play at dethroned.ai, raw calls public at dethroned.ai/eval, source on GitHub
