Causal Chain of Thought: Mitigating Attention Leakage via Context Isolation

Gabriele Dominici, Teague McMillan, Fazl Barez +2

Chain-of-thought (CoT) prompting elicits step-by-step rationales that appear to explain model predictions, but there is no guarantee these steps causally drive the final answer. In…

Position: Don't Just "Fix it in Post": A Science of AI Must Study Training Dynamics

Stella Biderman, Mohammad Aflah Khan, Niloofar Mireshghallah +3

What would it mean to have a scientific understanding of AI? Models are not static objects: they are snapshots of time-evolving processes shaped by data, objectives, architectures,…

Running the Gauntlet: Hard Agentic Tasks

Mykola Vysotskyi, Runqi Lin, Grzegorz Biziel +21

As agentic systems continue to evolve and are widely deployed in real-world scenarios, there is a growing demand to faithfully evaluate their capabilities. However, current benchma…

Make Mechanistic Interpretability Auditable: A Call to Develop Guidelines via Continuous Collaborative Reviewing

Michael Lan, Narmeen Fatimah Oozeer, Chaithanya Bandi +4

While mechanistic interpretability (MI) has produced important insights into neural network internals, the field has yet to establish a standardized system to audit experiments. As…

Interpretability Can Be Actionable

Hadas Orgad, Fazl Barez, Tal Haklay +9

Interpretability aims to explain the behavior of deep neural networks. Despite rapid growth, there is mounting concern that much of this work has not translated into practical impa…

Curveball Steering: The Right Direction To Steer Isn't Always Linear

Shivam Raval, Hae Jin Song, Linlin Wu +4

Activation steering is a widely used approach for controlling large language model (LLM) behavior by intervening on internal representations. Existing methods largely rely on the L…

AutoControl Arena: Synthesizing Executable Test Environments for Frontier AI Risk Evaluation

Changyi Li, Pengfei Lu, Xudong Pan +2

As Large Language Models (LLMs) evolve into autonomous agents, existing safety evaluations face a fundamental trade-off: manual benchmarks are costly, while LLM-based simulators ar…

Position: Token Taxes Can Mitigate AI's Economic Risks

Lucas Irwin, Tung-Yu Wu, Fazl Barez

AI-driven automation threatens to erode government tax bases, lower living standards, and disempower citizens--risks that mirror the 40-year stagnation of wages during the first in…

Old Habits Die Hard: How Conversational History Geometrically Traps LLMs

Adi Simhi, Fazl Barez, Martin Tutek +2

How does the conversational past of large language models (LLMs) influence their future performance? Recent work suggests that LLMs are affected by their conversational history in…

Same Answer, Different Representations: Hidden instability in VLMs

Farooq Ahmad Wani, Alessandro Suglia, Rohit Saxena +6

The robustness of Vision Language Models (VLMs) is commonly assessed through output-level invariance, implicitly assuming that stable predictions reflect stable multimodal processi…

Full-Stack Alignment: Co-Aligning AI and Institutions with Thick Models of Value

Joe Edelman, Tan Zhi-Xuan, Ryan Lowe +30

Beneficial societal outcomes cannot be guaranteed by aligning individual AI systems with the intentions of their operators or users. Even an AI system that is perfectly aligned to…

HACK: Hallucinations Along Certainty and Knowledge Axes

Adi Simhi, Jonathan Herzig, Itay Itzhak +7

Hallucinations in LLMs present a critical barrier to their reliable usage. Existing research usually categorizes hallucination by their external properties rather than by the LLMs'…
