Do features get crisper with scale? It's only gradual, argues Jacob Hilton

Responding to claims that features and circuits get crisper with scale, Jacob Hilton cites Gurnee & Tegmark's "Language Models Represent Space and Time" (arXiv:2310.02207), which shows linear spatial and temporal representations improving across Llama-2 model sizes (Figure 2).

But he argues this is only gradual improvement against exponentially growing model size — paired with his earlier point that an 88-node addition circuit scores 50% on faithfulness, the picture is that interpretability does not automatically keep pace with capability.
