Research Papers

Benchmarks & Evaluation

AISafetyBenchExplorer: A Metric-Aware Catalogue of AI Safety Benchmarks Reveals Fragmented Measurement and Weak Benchmark Governance — Catalogues the rapidly expanding LLM safety benchmark landscape and finds fragmented metrics, inconsistent coverage, and weak governance; calls for coordinated benchmark stewardship before safety claims can be trusted.
HazardArena: Evaluating Semantic Safety in Vision-Language-Action Models — Introduces a benchmark to evaluate whether VLA robot models can recognize and refuse semantically unsafe instructions, filling a critical gap where existing evaluations focus only on task success.
The Long-Horizon Task Mirage? Diagnosing Where and Why Agentic Systems Break — Systematic analysis of where LLM agents fail on long-horizon tasks; finds that apparent benchmark progress masks fundamental planning brittleness in real-world extended action sequences.

Security & Adversarial

Every Picture Tells a Dangerous Story: Memory-Augmented Multi-Agent Jailbreak Attacks on VLMs — Demonstrates that vision-language models can be jailbroken through persistent memory across multi-agent pipelines, exposing attack surfaces unique to multimodal agentic systems.
TEMPLATEFUZZ: Fine-Grained Chat Template Fuzzing for Jailbreaking and Red Teaming LLMs — A fuzzing framework that targets chat prompt templates to discover jailbreak pathways, revealing that many safety defenses are template-format dependent rather than semantically robust.
WebAgentGuard: A Reasoning-Driven Guard Model for Detecting Prompt Injection Attacks in Web Agents — Proposes a VLM-based guard layer that reasons about both visual and textual webpage content to detect prompt injection before a web agent acts on malicious instructions.
DeepSeek Robustness Against Semantic-Character Dual-Space Mutated Prompt Injection — Studies attacks combining semantic rewriting and character-level mutations against DeepSeek models, showing that single-dimensional defenses are insufficient against cross-space adversarial prompts.

Compliance & Regulation

ContextLens: Modeling Imperfect Privacy and Safety Context for Legal Compliance — Addresses the challenge that privacy and safety violations are context-dependent, proposing a framework for reasoning about incomplete contextual signals to support legal compliance in AI systems.
LLM-Redactor: An Empirical Evaluation of Eight Privacy-Preserving Techniques for LLM Requests — Evaluates eight approaches for redacting sensitive content before it reaches cloud LLM APIs, with practical guidance for coding agents and enterprise applications handling PII.

Alignment & Safety

Preventing Safety Drift in Large Language Models via Coupled Weight and Activation Constraints — Shows that fine-tuning degrades safety alignment even with benign data, and proposes a technique coupling weight and activation constraints during training to preserve refusal behaviors.
Malice in Agentland: Down the Rabbit Hole of Backdoors in the AI Supply Chain — Demonstrates that fine-tuning AI agents on web-browsing or tool-use interaction data introduces backdoor vulnerabilities, representing a new category of AI supply-chain attack vectors.

Applications

Development, Evaluation, and Deployment of a Multi-Agent System for Thoracic Tumor Board — Describes a production multi-agent clinical AI system that generates patient case summaries for multidisciplinary cancer tumor board review, with evaluation against expert physician assessments.

Guardrails & Robustness

Can We Watermark Low-Entropy LLM Outputs? — Examines the fundamental limits of watermarking for deterministic or low-entropy LLM outputs (such as code and structured data), finding that provably undetectable watermarking is infeasible in these regimes.
ASGuard: Activation-Scaling Guard to Mitigate Targeted Jailbreaking Attacks — Proposes an inference-time activation-scaling mechanism that detects and suppresses jailbreak attempts even when simple linguistic reformulations defeat alignment-based refusals.

Hyperscaler infrastructure bets: Microsoft’s $10B Japan commitment, Amazon’s Globalstar acquisition, and Meta-Broadcom’s MTIA expansion all signal that AI infrastructure competition has moved from model quality to geopolitical and hardware positioning.
AI safety benchmark fragmentation: AISafetyBenchExplorer exposes that the proliferation of safety benchmarks has outpaced governance, making it hard to compare or trust safety claims across models and vendors.
Physical AI beyond robotics: NVIDIA and Hitachi’s framing of trains and power plants as AI deployment targets signals that “physical AI” is expanding well beyond humanoid robots into critical national infrastructure.
