Research Papers

Benchmarks & Evaluation

AutomationBench — A new benchmark specifically targeting real business workflow automation: agents must coordinate across CRM, inbox, calendar, and messaging systems while discovering APIs autonomously and adhering to policy documents — exposing gaps that task-success-only benchmarks miss.
Do Agents Dream of Root Shells? Partial-Credit Evaluation of LLM Agents in CTF Challenges — DeepRed is an open-source CTF benchmark placing LLM agents in isolated Kali attacker environments to evaluate realistic offensive capability with fine-grained partial-credit scoring, revealing where frontier models actually fail in cybersecurity contexts.
AI Scientists Produce Results Without Reasoning Scientifically — Across 25,000+ agent runs in eight scientific domains, LLM-based research agents consistently produce plausible-looking outputs while failing to adhere to core epistemic norms of scientific inquiry — raising alarms about autonomous AI in research settings.
Four-Axis Decision Alignment for Long-Horizon Enterprise AI Agents — Proposes a four-axis evaluation framework (accuracy, regulatory compliance, transparency, safety) for high-stakes agentic decisions in domains like loan underwriting and clinical review, showing that single task-success metrics hide critical failure modes.

Security & Adversarial

ARES: Adaptive Red-Teaming and End-to-End Repair of Policy-Reward Systems — Identifies a “systemic weakness” in RLHF where both the base LLM and its reward model fail simultaneously at unsafe behaviors — and proposes an adaptive red-teaming loop that repairs both policy and reward model in tandem.
How Adversarial Environments Mislead Agentic AI — Formalizes the “Trust Gap”: agents are benchmarked on capability in benign settings but never tested for what happens when tools lie. Introduces Adversarial Environmental Manipulation as a formal attack class on tool-integrated agents.
Beyond Explicit Refusals: Soft-Failure Attacks on Retrieval-Augmented Generation — Proposes DEJA (Deceptive Evolutionary Jamming Attack), which defeats RAG systems by inducing fluent-but-uninformative responses rather than overt refusals — making the attack harder to detect while still degrading system utility.
Owner-Harm: A Missing Threat Model for AI Agent Safety — Argues that safety benchmarks focus on generic criminal harm while ignoring a commercially critical category: agents harming their own deployers. Cites real incidents including Slack AI credential exfiltration (Aug 2024) and Microsoft 365 Copilot calendar-injection leaks (Jan 2024).

Compliance & Regulation

Position: No Retroactive Cure for Infringement During Training — Argues that post-hoc compliance techniques — machine unlearning, inference-time guardrails — cannot cure legal liability from unlawful data acquisition during training, because copyright compliance hinges on data lineage, not model outputs. Directly challenges the ML community’s favored mitigation strategies.
Detecting Data Contamination in Large Language Models — Studies state-of-the-art Membership Inference Attacks (MIAs) under black-box conditions for detecting whether copyrighted documents are in LLM training corpora, addressing a core evidentiary challenge in AI IP litigation.

Alignment & Safety

Reasoning Structure Matters for Safety Alignment of Reasoning Models — Shows that safety failures in large reasoning models stem from reasoning structure, not just content — and that targeted post-training (AltTrain) can achieve effective safety alignment by modifying how models reason, not just what they output.
Human-Guided Harm Recovery for Computer Use Agents — Formalizes “harm recovery” as a distinct problem: when an agent executing real computer tasks reaches a harmful state, how do you optimally steer it back to safety in alignment with human preferences? Proposes preference-aligned recovery grounded in human feedback.

Applications

SafetyALFRED: Evaluating Safety-Conscious Planning of Multimodal LLMs — Extends the ALFRED embodied agent benchmark with six categories of real-world kitchen hazards to evaluate whether multimodal LLMs proactively address safety risks during task execution — finding they largely do not.
Reinforcement Learning Improves LLM Accuracy and Reasoning in Disease Classification from Radiology Reports — A two-stage approach (SFT + GRPO) significantly outperforms supervised fine-tuning alone on radiology report classification across three datasets, showing RL post-training can recover reasoning quality lost during SFT.

Guardrails & Robustness

Towards Understanding the Robustness of Sparse Autoencoders — Tests whether integrating pretrained Sparse Autoencoders (SAEs) into transformer residual streams at inference time can defend against gradient-based jailbreaks — across Gemma and three other model families — without modifying weights.

Key Themes

Powerful AI models as attack surfaces: The Mythos breach and the Cohere Terrarium vulnerability both illustrate that frontier AI systems introduce new categories of security risk — both through unauthorized access and through the AI’s own sandbox infrastructure.
Agentic enterprise AI reaches inflection point: Google, OpenAI, and Anthropic all made major agent platform announcements in this window; the race to own enterprise automation workflows is accelerating with real product launches, not just demos.
Supply chain attacks intensifying: npm ecosystem worms, Docker Hub tampering, and DPRK job-scam propagation all point to developer infrastructure as a high-value, high-vulnerability target in 2026.
Post-quantum ransomware: Kyber ransomware’s adoption of Kyber1024 encryption signals that threat actors are already building defenses against future decryption — a concern for long-lived encrypted data.
AI accountability gap: Research this cycle highlights a persistent pattern: AI systems (agents, reasoning models, scientific agents) perform well on benign benchmarks while failing in adversarial or safety-critical real-world conditions — and compliance/legal frameworks lag far behind.
Japan mobilizes on AI security: The finance minister’s Mythos briefing with major banks reflects growing official recognition in Japan that next-generation AI models pose systemic financial sector risks.
