Scaling Laws for Economic Productivity: Experimental Evidence in LLM-Assisted Translation [PDF]

open access: yesarXiv
This paper derives "scaling laws"--empirical relationships between the training compute of Large Language Models (LLMs) and their performance--for economic outcomes. In a preregistered online experiment, 300 professional translators completed 1,800 tasks using one of 13 LLMs (or a control).

Electrically Controlled Metal‐Insulator Heterogeneous Evolution for Infrared Switch and Perfect Absorption

open access: yesAdvanced Science, EarlyView.
Electrically controlled optical switch and perfect absorption are achieved in the long wavelength infrared range by modulating the proton‐mediated metal‐insulator phase mixture of a single layer of SmNiO3 on an opaque sapphire substrate. Such an infrared switch is reversible and tunable over a broad temperature and wavelength range, which could shed ...
