Researchers introduce AdaDSF, a method that converts pre-trained LLMs into depth-sparse models without full retraining by using cosine similarity between layer inputs and outputs to identify redundant computation. A lightweight router selects informative tokens per layer, and a feature-preserving alignment objective maintains output quality. Evaluated on GPT-NeoX and Qwen2.5, AdaDSF reduces inference FLOPs while outperforming baselines including MoD, D-LLM, and DLO under comparable sparsity budgets.
