Bits per Joule: A Thermodynamic Framework for Intelligence Efficiency (and What It Means for Scaling Ceilings and FOOM)
TL;DR A new paper, "Thermodynamic Limits of Physical Intelligence", establishes energy-efficiency benchmarks for learning and control in physical systems. Paper results: * We propose two bits-per-joule metrics—thermodynamic epiplexity per joule (learning efficiency) and empowerment per joule (control efficiency)—under explicit accounting conventions. * In closed-cycle benchmarking with boundary closure, epiplexity acquisition...
