Emergent One-Third Scaling Law as Attention Tries to Concentrate

Yizhou Liu, Sara Kangaslahti, Jeff Gore

The neural scaling law relating longer training to better performance through a power law is central to today's large language models (LLMs), yet its origin remains debated. One re…

Thinking at the Right Size: Amortized Distillation Across Post-Trained LLMs

Yan Zhou, Sara Kangaslahti, Jonathan Geuter +4

Practical deployment of large language models (LLMs) requires families of post-trained variants---instruction-tuned, reasoning-tuned, and chat-style models---each at multiple sizes…

Understanding Layer Patching in Model Size Interpolation

Sara Kangaslahti, Jonathan Geuter, Nihal V. Nayak +3

Zero-shot model size interpolation aims to create new models of intermediate target sizes by combining existing models without additional training. Recent work on boomerang distill…

Inverse Depth Scaling From Most Layers Being Similar

Yizhou Liu, Sara Kangaslahti, Ziming Liu +1

Neural scaling laws relate loss to model size in large language models (LLMs), yet depth and width may contribute to performance differently, requiring more detailed studies. Here,…
