Role-playing agent benchmarks fail to measure real user interactions

Researchers identify fundamental flaws in how role-playing agents are currently evaluated, showing that fixed dialogue histories and detached rubrics fail to capture real multi-turn conversational dynamics. The work addresses a critical gap in LLM benchmarking: existing evaluation frameworks don't account for how individual user preferences shape interaction outcomes, limiting our ability to reliably measure RPA capabilities or compare systems. This matters because RPAs represent a major consumer LLM use case, and broken evaluation metrics mean deployed systems may underperform in actual user settings. The paper proposes person-aligned simulation as an alternative, suggesting the field needs fundamentally different assessment approaches as role-playing becomes mainstream.

Copilot Word documents weaponized as self-replicating prompt injection vectors

Researcher Håkon Måløy has demonstrated a critical escalation in LLM attack surface: prompt injection vulnerabilities in Microsoft Word's Copilot integration can now self-replicate across documents. By embedding hidden instructions in source material, an attacker can trick Copilot into propagating malicious payloads into newly generated documents, creating a worm-like infection vector. This transforms prompt injection from a single-request exploit into a persistent, document-mediated attack that spreads through normal collaboration workflows. The finding exposes a fundamental tension in agentic AI systems: as models gain document manipulation capabilities, they become both more useful and more dangerous as infection vehicles.

World models gain mental state tracking for human behavior prediction

Researchers propose Mental World Modeling, a framework that extends traditional world models by treating agent beliefs, intentions, and social reasoning as first-class components rather than post-hoc interpretations. Current predictive systems track physical state evolution but miss the hidden mental variables that actually drive human behavior, leading to action predictions that fail despite accurate scene understanding. MWM couples physical and mental state tracking, enabling systems to simulate how actions reshape both what agents do and what they know or believe. This addresses a fundamental gap in embodied AI and multi-agent reasoning, with implications for robotics, dialogue systems, and human-AI interaction.
