Neuron Explorer: 3D visualization of per-layer Transformer neuron activations

arthurcolle · x · 2026-10-27

The author shares a screenshot of Neuron Explorer, an interpretability workbench that lays out Transformer layers as a 3D corridor. It supports feature search (e.g. "files"), per-layer neuron connection graphs, logit-lens views per layer, and a side panel showing live token/neuron activation details for the current chat. No accompanying text or project link is given in the post.
