The Lantern Tavern during a storm
OpenAI Build Week Competition Demo

One scene. Any action. Consistent consequences.

This focused three-minute demo shows the core invention: GPT‑5.6 converts free-form player intent into structured atomic actions, a deterministic engine validates items and world state, and GPT‑5.6 narrates only the approved result.

Checking the AI runtime…
1. Interpret

Natural English becomes stable action IDs.

2. Resolve

The engine checks inventory, targets, skills, and persistent flags.

3. Remember

The changed tavern, NPC memory, and quest result are saved.

Try this exact action—or invent your own:

“Tie a rope to the pillar, spill lamp oil on the stairs, hide behind the bar, and lure the raiders into the trap.”
