Researchers have developed an effective distillation pipeline to transfer knowledge from large language models (LLMs) with quadratic attention to sub-quadratic architectures based on xLSTM. This method aims for lossless distillation, defined by comparable Win-and-Tie rates between student and teacher models. The pipeline includes an additional merging stage to combine linearized experts into a single model, successfully distilling models from the Llama, Qwen, and Olmo families. In many cases, the xLSTM students achieved performance close to, or even exceeding, their teacher LLMs on various downstream tasks, presenting a step towards more energy-efficient LLM replacements.

IMPACT This research offers a path towards more energy-efficient and cost-effective LLMs by enabling smaller, sub-quadratic models to retain much of the performance of larger, quadratic attention-based models.
RANK_REASON The cluster contains an academic paper detailing a new method for distilling LLMs into a different architecture. [lever_c_demoted from research: ic=1 ai=1.0]
