I Turned Structured Output Into a Game 🎮
Token Arcade gamifies structured LLM output constraints for interactive learning
A Hugging Face creator built 'Token Arcade,' an interactive game that teaches constrained decoding by letting users manually select which tokens are valid at each step of LLM inference. The demo illustrates how structured output enforcement works at the token-probability level, blocking tokens that violate schema constraints. It's a solid educational tool for developers learning about structured inference, but not a major industry signal.
