Researchers propose using thermodynamic phase-transition theory to understand the dynamics of language model alignment. They introduce a case study based on material crystallization, identifying three phases: a high-entropy liquid phase in pretrained models, a nucleation phase during supervised fine-tuning where behavior collapses to a seed distribution, and a settling phase with reinforcement learning that redistributes probability but maintains concentration. The study suggests this physical framework can offer insights into the origins and limitations of alignment-induced structure in models. AI
