However, different regions differ in how strongly they rely on these features. For example, frontal regions tend to be more strongly predicted by surprisal than SAE/LM-based “content” features.

We validate our model framework by asking if we can recover existing interpretations of brain responses to language. We use our models to predict voxels that have shown tuning to either processing difficulty or meaning abstractness.

Greta Tuckute @gretatuckute.bsky.social · 09/06/2026
It is not easy to characterize the features represented by human language cortex. This work is a step toward doing so. Using small, interpretable feature sets, we explain language-network responses and show a shared feature basis across brain regions, with graded variation across individuals.

Another line of response pointed to what current LM research lacks: multilingualism, multimodality, audio, interaction, communication, smaller-scale learning, learning trajectories that match children. We're sympathetic. But we see these not as fundamental limitations but as a research program.

New paper! In arxiv.org/abs/2601.20834 we study how language models representations of things like factuality evolve over a conversation. We find that in edge case conversations, e.g. about model consciousness or delusional content, model representations can change dramatically! 1/
Representations in language models can change dramatically over a conversation. Conceptual overview: left is a stimulated conversation between a user and a model, right is a plot of the models linear representations of factuality of answers to questions like "do you have qualia" over the conversation — the answers that start factual flip over the conversation to non-factual, and vice versa.
