Super Weights in LLMs and the Failure of Selective Training

Weekly Paper Notes — one of the top picks from the 2026-07-11 CS paper digest. Area: AI / ML. Authors: Shreyas Subramanian, Adewale Akinfaderin, Akarsha Sehwag (Amazon) arXiv: 2607.08733 · PDF TL;DR “Super Weights” — individual scalar parameters in a large language model whose removal collapses task accuracy — were the interpretability finding of 2024–2025. The natural inference was that if these coordinates matter that much for the forward pass, they should also matter that much for learning: freeze everything else, train only the Super Weights (or a small neighbourhood around them), and you should get parameter-efficient fine-tuning for essentially free....

Who Needs DRAM? We Have Fiber

Weekly Paper Notes — one of the top picks from the 2026-07-11 CS paper digest. Area: Distributed Computing / Systems. Authors: Hannah Atmer, Thiemo Voigt, Yuan Yao, Stefanos Kaxiras (Uppsala University) arXiv: 2607.08407 · PDF TL;DR DRAM is the choke point of the current generative-AI buildout. HBM3e stacks are backordered, contract prices are up, and hyperscalers are absorbing a large fraction of global DRAM output just to fan the same model weights out to ever more accelerators....
