MetaOthello: A Controlled Study of Multiple World Models in Transformers In Progress

with Aviral Chawla, Juniper Lovato · arXiv preprint, 2026

We introduce MetaOthello, a suite of Othello game variants designed to investigate how transformers organize multiple world models within shared representations. We find that transformers trained on mixed-game data converge on a mostly shared board-state representation that transfers across variants.
