Circuit Atlas
Prototype interface for exploring SAE feature clusters and their interactions across transformer layers.
Circuit Atlas is a prototype interface for making circuit-discovery work easier to inspect. The backend prepares a corpus of feature clusters and interactions; the frontend turns that into a navigable graph with constellation, circuit-board, and feature-detail views.
I would describe this as research tooling rather than a finished discovery system. The useful part is the shape of the interface: moving from thousands of low-level SAE features toward something you can browse, filter, and question. That connects directly to the dissertation problem, where interpretability work only becomes useful once there is a way to inspect the structure it finds.
