The field of large language models is moving towards improving efficiency and reducing computational costs. Researchers are exploring various techniques such as funneling, pruning, and compression to achieve this goal. Notable papers include 'Revisiting Funnel Transformers for Modern LLM Architectures' which investigates the impact of funneling in contemporary transformer architectures, and 'Nemotron-H: A Family of Accurate and Efficient Hybrid Mamba-Transformer Models' which introduces a family of hybrid models that offer better or on-par accuracy compared to other state-of-the-art models while being up to 3x faster at inference. Another noteworthy paper is 'Entropy-Based Block Pruning for Efficient Large Language Models' which proposes an entropy-based pruning strategy to enhance efficiency while maintaining performance.
