Can Light-Connected AI Enable Bigger Brains?

Our founder, Jeff Shainline, sat down with Sunny Bains' Brains and Machines podcast to talk through the physics behind Great Sky's superconducting neural networks — from Josephson junctions and single-photon detectors to why operating at 4 Kelvin is a feature, not a drawback.

The conversation covers the fundamentals of our hardware platform, how we're scaling from thousand-parameter chips toward wafer-scale systems, and why we believe optical communication at the single-photon level is the only path to truly brain-scale computing. Jeff also shares projections on cost and energy efficiency for large language models and video analysis, and previews the physical limits that shape everything we're building toward.
