- What changed
- Researchers demonstrated that linear probe weights alone do not reliably identify causal features in language models, and introduced a sparse-autoencoder decomposition diagnostic to identify behaviorally causal features.
- Why you should care
- Linear probe accuracy alone is insufficient to establish causal behavioral drivers in language models.

- What to watch next
- Replication of sparse autoencoder feature decomposition across larger model families and additional safety datasets.
