New research from Yann LeCun and collaborators at NYU. It's a really good read for anyone working on efficient Transformer inference. The paper dissects two recurring phenomena in Transformer language models: massive activations (where a few tokens exhibit extreme outlier values, and attention sinks (where certain tokens attract disproportionate attention regardless of semantic relevance). They show the co-occurrence is largely an architectural artifact of pre-norm design, not a fundamental property. Massive activations function as implicit model parameters. Attention sinks modulate outputs locally. Why does it matter? These phenomena directly impact quantization, pruning, and KV-cache management. Understanding their root cause could enable better engineering decisions for efficient inference at scale. Paper: https://t.co/wfzeDpfu4x
