AI in a Role-Playing Game: How to Keep an LLM in Check (Beyond The Verge)
Beyond The Verge's developers have tackled the usual LLM problems in role-playing games: model drift, amnesia and rule violations. Their solution is radical: an authoritative backend built on FastAPI with PostgreSQL manages the inventory, the map and the game state, while the LLM only describes events. The model describes what happens, and the backend controls the state. As a result, the mechanics are deterministic and the game scales.

Beyond The Verge, a text-based role-playing game powered by an LLM, ran into a classic problem: models forget context, break the rules of the game and conjure items out of thin air.
Can a neural network run a role-playing game?
An LLM is generative by nature, while an RPG demands determinism. The model remembers only what fits in its context window, cannot tell imagination from game state, and may spontaneously break the game's logic.
How do you keep a model in check in a text game?
Beyond The Verge chose to take control of the mechanics away from the model rather than try to tame it, leaving the neural network only the job of generating descriptions.
