LowRankArena is a standardized evaluation platform for SVD‑based low‑rank compression of large language models, unifying task versions, compression budgets, comparison regimes, and inference measurements. It provides a reproducible pipeline with over 3 TiB of released compressed checkpoints, enabling consistent comparisons across methods. An audit of five representative SVD techniques using LowRankArena shows that prior reported gains are highly conditional, with performance leaders and tiers shifting across backbones and keep ratios, and that nominal low‑rank savings often yield limited end‑to‑end speedups.

SkipCat introduces a rank‑maximized low‑rank compression framework for large language models, combining intra‑layer shared low‑rank projections and block‑skipping techniques to reduce redundancy and computational overhead. By allowing higher retained ranks while maintaining the same compression rate, SkipCat achieves a 7% accuracy improvement on zero‑shot tasks compared to prior low‑rank methods, all without additional fine‑tuning.

The paper introduces Low‑Rank Conditional Computation (LRCC), a method that adds token‑dependent computation to pretrained language models by training lightweight routers to select among nested low‑rank paths while keeping low‑rank factors frozen. LRCC is evaluated on Llama and Qwen models, showing improved predictive performance over static low‑rank compression, including a 7.6‑percentage‑point gain in downstream accuracy on Llama‑2‑7B. The study also demonstrates that LRCC enhances perplexity and downstream accuracy on Llama‑3.2‑1B at matched decoding latency and analyzes the routers’ path choices to assess token‑wise path usefulness.

The paper introduces Layer-wise Error Modeling Search (LEMS) and KFAC-SVD to improve low-rank SVD-based compression of large language models. LEMS addresses global rank allocation by using a layer-wise error surrogate and an ILP formulation, while KFAC-SVD enhances decomposition quality by employing token-wise statistics to avoid rank collapse. Experiments on Mistral, Qwen3, and Llama 3 show LEMS yields up to 4.8 pp zero‑shot accuracy gains and KFAC‑SVD achieves an average perplexity improvement of 15%.
