PresenceBench: An Exploratory Evaluation of Large Language Model Adaptation to User State

Read the original on arXiv AI →

PresenceBench is a new tool for measuring how large language models adapt to a user’s functional state—readiness, flow, and stability—while maintaining task quality and safety. The study evaluated four models (Claude Sonnet 5, DeepSeek V4 Pro, Gemini 3.6 Flash, GPT‑5.6 Terra) across 18 single‑turn, six fixed‑three‑turn, and six simulated natural‑conversation scenarios, finding that providing a synthetic state improved human preference scores above chance for all models. However, the study could not conclusively determine whether improvements depended on the correct state (specificity) and noted that policy delivery reduced cost and token usage without proven efficiency gains or safety concerns.

Interlock: From Local Correctness to Task Completion in Long-Horizon Agents

Interlock is a framework that transforms long‑horizon tasks into typed completion graphs, linking evidence, decisions, and required effects through grounding, coupling, and realization edges. It compiles these graphs into a resettable workspace, a public request, and an evaluation rubric, and uses source‑coverage, public‑input, and agent‑as‑judge reviews to ensure that all mandatory requirements are met. Fine‑tuning Qwen3.6 backbones on Interlock‑generated trajectories improves pass rates on AutomationBench, JobBench, and Harvey LAB, showing that the synthesized experience benefits external task environments.

From Offline Proxies to Online Decisions: A Layered Engagement Evaluation Framework for Conversational AI

The paper presents a layered framework for evaluating conversational AI by aligning offline proxy signals with online A/B experiment outcomes. It introduces a three‑step alignment chain—behavioral label to product outcome, classifier to candidate behavior, and offline signal to experiment effect—alongside an audit protocol that compares confidence intervals and rankings. In a real‑world deployment, the composite proxy achieved 81.1% F1 versus 34.3% for the raw classifier, correctly predicting direction on all 113 contrasts and enabling efficient prioritization of candidate models before costly online testing.

ObserverBench: Testing Mechanistic Estimates for Intervention and Control

ObserverBench is a benchmark framework that evaluates whether internal mechanistic estimators—called observers—are suitable for guiding interventions, control, or safety actions in language models. It separates estimation accuracy from the loss incurred by the chosen action, showing that accurate predictions do not always lead to better decisions. Experiments on GPT‑2‑small, Qwen2.5‑7B, Gemma‑2‑9B‑it, and Qwen3.5‑9B demonstrate that observers trained on action loss can reduce deployment loss, while traditional metrics like AUROC may rank monitors differently from actual performance.

Uncertainty Quantification for Computer-Use Agents: A Benchmark across Vision-Language Models and GUI Grounding Datasets

arXiv:2606. 25760v1 Announce Type: new Abstract: Computer-use agents turn vision-language model (VLM) predictions into executable GUI clicks, so reliable uncertainty estimates are essential for rejection, calibration, miss-severity ranking, and spatial safety regions.
