Towards Physical Intuitions for Alignment Dynamics: A Case Study With Randomness Crystallization

arXiv:2606.29933v1 Announce Type: new Abstract: The alignment of language models is typically studied through the lens of capability benchmarks, but the dynamics of how models change during post-training remain poorly understood. We argue that the physical sciences, and thermodynamic phase-transition theory in particular, offer a principled and underexplored vocabulary for reasoning about these dynamics. As a case study, we instantiate this position through the lens of material Crystallization, which is a well-studied thermodynamic phase transition. For tasks like random number generation, thi

Why this matters
Why now

The increasing complexity and opacity of large language models necessitate new theoretical frameworks to understand their emergent behaviors, particularly during post-training alignment processes.

Why it’s important

A deeper, physics-inspired understanding of AI alignment dynamics could lead to more robust, controllable, and predictable AI systems, impacting their deployment across critical applications.

What changes

This research introduces a novel theoretical lens, drawing from thermodynamics, for analyzing AI alignment, potentially shifting the methodology from empirical benchmarks to more principled theoretical models.
