In the team's tests, vision did not improve performance and sometimes worsened it by causing models to hallucinate nonexistent entities and make claims unrelated to the game state.

“As you said, adding this niches didn't improve things, and it sometimes made it even worse because they started hallucinating entities that weren't there and started doing often,”

“went on tangents that weren't actually real in the game state.”

“Right now, at least, the vision actually wouldn't improve.”
