LLM Compression by Block Removal with Constrained Binary Optimization

arXiv:2602.00161v2 Announce Type: replace-cross Abstract: In this paper, we formulate the compression of large language models (LLMs) by optimally deleting transformer blocks (``block removal'') as a constrained binary optimization (CBO) problem that can be mapped to a physical system (Ising glass), whose energies are a strong proxy for downstream model performance. This formulation enables an efficient ranking of a large number of candidate block-removal configurations yielding many high-quality, non-trivial solutions beyond those only removing consecutive regions. Our method performs strongl

Why this matters
Why now

The proliferation of LLMs and the increasing computational demands they place on infrastructure make efficient compression methods critical for broader adoption and deployment.

Why it’s important

This research provides a novel, more effective method for compressing LLMs, which directly addresses the high computational and energy costs associated with large models.

What changes

The ability to significantly compress LLMs without substantial performance degradation alters the cost-benefit analysis for deploying these models, potentially enabling wider application and accessibility.
