Stanford Prof Anshul Kundaje on Weight Space Editing: Replicated Across Models, Limits Still Unclear

Stanford professor Anshul Kundaje shares an updated take on a weight space editing paper: he clarifies that the paper's baselines lacked extensive tuning (a point the paper could have made clearer), but the method does work and has now been replicated by several others across different model types. He sees it as early days—the chosen tasks were simple but well-chosen illustrations—and expects models could be trained to be much better at weight space editing now that the capability has been highlighted.
