Every feature, sortable

All features in this atlas, with statistics computed from the dictionary; lifecycle labels follow the paper's rules. Sort by when a feature peaked, filter by lifecycle, search by token. Click a row to open the feature page.

Each row is one crosscoder feature: a readout direction with one identity across the 32 checkpoints. By default the columns are its trajectory, lifecycle label, headline top tokens and most enriched concept list, sorted by vocab focus; "+ technical columns" adds peak step, vocab focus, the step-1,000 norm shift and more. Every column is defined on the About & data page.
