Independent replication by Redwood Research confirmed the key results in the 'Demonstrating Superposition,' 'Superposition as a Phase Change,' and 'Geometry of Superposition – Uniform Superposition' sections of the Elhage et al. 2022 paper.
Summary
A second, independent research team reproduced the core findings showing that neural networks pack more internal features into their activations than they have neurons, including the specific geometric structure and phase-transition behavior of that packing. This matters because the superposition theory is no longer a single-lab claim but a verified foundation, so downstream reasoning about interpretability, feature extraction, and model behavior can safely build on it without worrying it might be an artifact.
