arXiv:2604.24938v3 Announce Type: replace Abstract: Depth pruning improves the inference efficiency of large language models by removing Transformer blocks. Prior work typically treats layer redundancy as an inherent structural property of pretrained networks, emphasizing importance criteria and search algorithms to identify removable layers. In this study, we empirically investigate depth pruning from a functional perspective. Evaluating representative LLM families across diverse calibration configurations and multiple search algorithms, we show that different configurations produce different
The research is emerging as the drive for more efficient LLMs collides with inherent architectural redundancies, pushing for novel optimization techniques.
This research suggests a fundamental shift in how LLMs can be optimized for inference, potentially making deployment more efficient and accessible for a wider range of applications.
The focus for LLM depth pruning is shifting from complex layer redundancy search to emphasizing calibration, simplifying optimization and potentially improving model performance and efficiency.

LLMs become more resource-efficient, leading to lower operational costs and broader adoption.
Increased accessibility and reduced cost of LLMs could accelerate the development and deployment of AI-driven applications and agents.
More efficient LLMs might enable new types of localized or edge AI applications, reducing reliance on centralized compute and impacting compute supply chains.
