Full story

A team of researchers has developed a system called Twin that can learn game rules and goals from scratch, without human intervention. This breakthrough could have significant implications for artificial general intelligence (AGI). The system uses a frontier coding agent to write an executable world model for completing continual learning tasks, such as the ARC-AGI-3 games. Traditional approaches to this problem require hand-engineering custom models for each task, but Twin can construct its own models from simulation and interaction alone. The system's inductive prior over grid games is strong enough to recover the true transitions of the game and the goal on nearly all levels. Replay validation happens in a twin world model, which enforces that an action is not taken without a valid reason.
