## AI 摘要

微软研究院新研究表明，4B模型经SocialRL训练后可在谈判中胜过GPT-5系列模型。训练后78%的买家开场报价低于目标价，而未训练模型仅3%。Cascade RL与多教师蒸馏将专家整合为单一4B模型，平均效用0.627，高于GPT-5.1的0.619和GPT-5.2的0.613。

Very interesting new work from Microsoft Research.

They show that a 4B model can be tuned to out-negotiate the GPT-5 family of models.

The dispositions that make an assistant pleasant make it a poor delegate. They show that a friendly frontier model volunteers its principal's private information and concedes at the first sign of resistance.

SocialRL trains social reasoning directly in a 4B model across six principal-driven domains including negotiation, job interviews and marketplace haggling. After training, 78% of buyer openings anchor below target against 3% untrained.

Cascade RL and multi-teacher distillation consolidate the specialists into one 4B at 0.627 average utility, above GPT-5.1 at 0.619 and GPT-5.2 at 0.613.
