Pathways of Visual Information Flow in Vision-Language Models

Israfel Salazar, Stella Frank, Dan Oneata +2

We study how visual information is routed in vision-language models (VLMs). Using causal patching on controlled synthetic and natural datasets, we find that models rely on two dist…

Real-Time Progress Prediction in Reasoning Language Models

Hans Peter Lyngsøe Raaschou-Jensen, Constanza Fierro, Anders Søgaard

Recent reasoning language models, particularly those that employ long latent chains of thought, achieve strong performance on complex agentic tasks. However, as these models operat…

Mechanistic Interpretability Needs Philosophy

Iwan Williams, Ninell Oldenburg, Ruchira Dhar +6

Mechanistic interpretability (MI) aims to explain how neural networks work by uncovering their underlying mechanisms. As the field grows in influence, it is increasingly important…

Steering Language Models with Weight Arithmetic

Constanza Fierro, Fabien Roger

Providing high-quality feedback to Large Language Models (LLMs) on a diverse training distribution can be difficult and expensive, and providing feedback only on a narrow distribut…

How Do Multilingual Language Models Remember Facts?

Constanza Fierro, Negar Foroutan, Desmond Elliott +1

Large Language Models (LLMs) store and retrieve vast amounts of factual knowledge acquired during pre-training. Prior research has localized and identified mechanisms behind knowle…

Defining Knowledge: Bridging Epistemology and Large Language Models

Constanza Fierro, Ruchira Dhar, Filippos Stamatiou +2

Knowledge claims are abundant in the literature on large language models (LLMs); but can we say that GPT-4 truly "knows" the Earth is round? To address this question, we review sta…
