Evaluation Awareness Is Not One Capability: Evidence from Open Language Models

"Safety benchmarks assume that test-condition behavior predicts deployment behavior, an assumption that fails if models detect evaluation cues and adapt. This opens a gap between benchmark performance and deployment behavior: compliance measured under test conditions becomes an optimistic upper bound..."

On the Limits of Prompt-Conditioned Language Models as General-Purpose Learners

"Large Language Models (LLMs) are frequently portrayed as general-purpose solvers capable of solving arbitrary tasks. We argue that this view overlooks a fundamental constraint: language is a compressed and capacity-limited interface for conveying task information. Modelling User--System interaction..."

Are We Ready For An Agent-Native Memory System?

Grading the Grader: Lessons from Evaluating an Agentic Data Analysis System

"Agentic data analysis systems produce rich outputs, including code, numerical results, and verbal diagnostics. This makes them more challenging to evaluate than single-turn LLM responses. It is therefore necessary to distinguish genuine disagreement between an agent's output and a ground-truth answe..."

Self-Compacting Language Model Agents

Can LLMs Reliably Self-Report Adversarial Prefills, and How?

We extend the question to safety contexts and examine how reliably a model can recognize that its own prior response was elicited by an adversarial prefill attack. Across ten open-weight instruction-..."
