UC San Diego Paper Adds Theory of Mind to 7B Agent
The reward-shaping trick means theory of mind gets baked into the weights rather than bolted on at inference, so negotiation and cooperation gains come with zero added serving cost. Agent builders working on multi-agent negotiation or role-play can borrow this training recipe directly. Compared with the usual memory-summary heuristics, an explicit partner-model reward targets the exact failure mode of misreading intent.
