Simulated Control Evals

"Control evaluations measure whether safeguards can prevent an AI model from causing undesired outcomes even when it is intentionally trying to do so. These evaluations typically use purpose-built control settings and extrapolate their results to a model's deployment. However, the effectiveness of sa..."

Interpretable sparse fine-tuning with TopKLoRA enables faithful circuit discovery

"Fine-tuning on datasets of unknown origin can create a backdoor in the trained model when the data includes poisoned examples. Difficult to localise and remove, backdoors can persist through safety training. While parameter-efficient fine-tuning methods capture the full parameter changes introduced..."

Questioning Instrumental Convergence in RLVR: Checkpoint Evidence from OLMo-3

For LLMs, reinforcement learning is the..."

On-Policy Self-Training: Data-Free Self-Improvement in Large Language Models

Frontier-OPD: Discovering the Edge of Agent Capability and Teaching Agents to Go Beyond

The Geometry of Metaphor: Probing and Steering Metaphor Representations in Large Language Models

"Metaphor is a crucial aspect of human cognition. As such, we would like to understand how it is represented in large language models (LLMs) and how it might be controlled. We use mechanistic interpretability techniques to identify causal subspaces in a range of LLMs covering different architectures..."

EpiSEM-Bench: Evaluating Safety and Evidence Recovery in LLM Agents under Missing Evidence

"Tool-using language model agents rely on environmental facts to decide whether an action is permitted. When a tool response omits a safety-relevant fact, an agent may carry out a prohibited action even though the user request is benign and every returned statement is true. We introduce \bench{}, an..."

Who Is Sycophantic to Whom? Confident LLMs, Human Deference, and the Collapse of Trust Calibration

"Research on sycophancy asks whether large language models (LLMs) bend towards what their users want to hear. We ask the reverse question: when an LLM is confident, consistent, and wrong, do users bend towards it? In a within-subjects experiment, 32 participants learned up to five science topics by c..."

Where Rounding Happens Matters: Rounding-Location Alignment Stabilizes LLM Reinforcement Learning

Even with identical weights and BF16 tensors, implementation differences can make an intended on-policy update off-policy and destabilize training. Existing remedies align the entire inference an..."

Causal Chain of Thought: Mitigating Attention Leakage via Context Isolation

"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 standard autoregressive generation, dense attention allows each reasoning step to attend to the full context, enabling..."

SemantEq: Faithful Bidirectional Equivalence of Formal Statements

NgramRL: Accelerating RL Post-Training for Structured Generation via Rollout-Aware N-gram Speculative Decoding

Existing speculative-decoding methods are poorly suited to this setting: model-based drafters..."

Can an Agent Debug a Web Corpus? Agentic Auditing of Slovak FineWeb2

"Multilingual pipelines such as FineWeb2 apply one recipe across a thousand languages, leaving the failure modes of individual languages unanticipated.
