Lower toxicity scores may hide changes in representational harm rather than its removal. Safety evals need topic and demographic analysis alongside surface-form classifiers.

Verifiable by Construction: Claim-Level Evaluation of Verbatim Citation in Clinical Question Answering

Molecular Déjà Vu: Digit-Level Retrieval of Published Values in Frontier Language Models
arXiv · 2026-09-04

Molecular benchmark accuracy can reflect retrieval of published values rather than prediction. Contamination audits should test digit-level recall and repeat runs across reasoning settings.

When LLM Decompilers Recompile More and Preserve Less

Legibility is Not Interpretability: Comparing Judged and Actual Importance in Chain-Of-Thought Reasoning
arXiv · 2026-09-03

Readable chain-of-thought is not a reliable map of which steps caused a correct answer. Treat step-level LLM critiques as partial signals, especially on already-correct traces.

SWE-Gate: Passing Functional Tests Is Not Enough for Software Engineering Agents
arXiv · 2026-09-03

SWE-Gate shows why green tests are an incomplete agent-eval signal: 221 of 644 functionally passing repairs still violated constraints derived from code review.

From Deceptive Outputs to Deceptive Mechanisms: A Causal Framework for Language-Model Deception Research
arXiv · 2026-09-03

A causal framework separates deceptive-looking model output from the mechanism producing it, giving agent evaluators a stricter basis for claims about intent or agency.

User Feedback Provides a Unique Signal that LLMs Can not Detect
arXiv · 2026-09-02

User feedback helps models repair targeted faults, but LLM judges often miss those repairs. Agent evals should retain human feedback and avoid treating model preference as ground truth.

Beyond Scores: Understanding LLM-as-a-Judge Mechanisms in Summarization Evaluation
arXiv · 2026-09-01

Mechanistic tests suggest two open LLM judges route local errors early and form ratings late, giving eval builders concrete layers and components to probe for judge failures.
