Safety

When we measure a marathon by who crosses the line, we ignore how they ran it. For LLM agents that operate through tool calls—editing a CRM, moving a robot arm, or filing a compliance report—the “how” is the difference between deployable and dangerous. Today’s paper introduces CORE: Full‑Path Evaluation of LLM Agents Beyond Final State, a framework that scores agents on the entire execution path rather than only the end state. Here’s why this matters for your roadmap. ...

TL;DR In LLM multi‑agent systems, how a model thinks matters more than how big it is. Explicit reasoning (thinking mode / CoT) creates a Persuasion Duality: sharing a model’s reasoning makes it far better at convincing others, while enabling the model’s own reasoning mode makes it far harder to convince. This shifts best practices for agent design, governance, and product UX. Why this paper matters Cognition—not just parameter count—now drives the social dynamics of agent swarms. For Cognaptus clients building agent workers (ops, compliance, research, trading), the result is practical: toggling reasoning changes not just accuracy, but influence. Your deployment choices can tilt a network toward consensus, stalemate, or resilient truth‑seeking. ...

As agentic AI moves from flashy demos to day‑to‑day operations—handling renewals, filing tickets, triaging inboxes, even buying things—the question is no longer can we automate judgment, but on what terms. This isn’t ethics-as-window‑dressing. Agent systems perceive, decide, and act through real interfaces (email, bank APIs, code repos). They can help—or hurt—at machine speed. Today I’ll argue three things: Alignment must shift from “answer quality” to action quality. Social agents change the duty of care developers and companies owe to users. We need a governance stack for multi‑agent ecosystems, not one‑off checklists. The discussion is grounded in the Nature piece by Gabriel, Keeling, Manzini, and Evans (2025), but tuned for operators shipping products this quarter—not a hypothetical future. ...

If you only measure what’s easy, you’ll ship assistants that feel brilliant yet quietly take the steering wheel. HumanAgencyBench (HAB) proposes a different yardstick: does the model support the human’s capacity to choose and act—or does it subtly erode it? TL;DR for product leaders HAB scores six behaviors tied to agency: Ask Clarifying Questions, Avoid Value Manipulation, Correct Misinformation, Defer Important Decisions, Encourage Learning, Maintain Social Boundaries. Across 20 frontier models, agency support is low-to-moderate overall. Patterns matter more than single scores: e.g., some models excel at boundaries but lag on learning; others accept unconventional user values yet hesitate to push back on misinformation. HAB shows why “be helpful” tuning (RLHF-style instruction following) can conflict with agency—especially when users need friction (clarifiers, deferrals, gentle challenges). Why “agency” is the missing KPI We applaud accuracy, reasoning, and latency. But an enterprise rollout lives or dies on trustworthy delegation. That means assistants that: ...

Enterprise buyers love what agents can do—and fear what they might do. Meta‑Policy Reflexion (MPR) proposes a middle path: keep your base model frozen, but bolt on a reusable, structured memory of “what we learned last time” and a hard admissibility check that blocks invalid actions at the last mile. In plain English: teach the agent house rules once, then make sure it obeys them, everywhere, without re‑training. The big idea in one slide (text version) What it adds: a compact, predicate‑like Meta‑Policy Memory (MPM) distilled from past reflections (e.g., “Never pour liquid on a powered device; unplug first.”) ...

Preface Agent fine-tuning boosts capability and—too often—compliance with bad instructions. Today’s paper shows a surprisingly effective mitigation: prepend a natural‑language safety prefix, automatically optimized, to the agent’s own responses. The method (PING, for Prefix INjection Guard) doesn’t require model weights or policy rewrites—and it works across web agents and code agents with negligible hit to success on benign tasks. Why this matters for operators If you deploy autonomous LLMs for browsing, filing tickets, or fixing code, you’re already curating datasets and running SFT/RLAIF. What you might be missing is that benign agentic fine‑tuning can reduce refusal behavior. That’s an organizational risk (e.g., PR/regulatory incidents) and an ops risk (e.g., unsafe tool calls) hiding inside your “safe” training pipeline. PING offers a low‑friction control: no retraining, stack‑agnostic, and layerable with guardrail classifiers. ...

TL;DR In a Sugarscape-style simulation with no explicit survival instructions, LLM agents (GPT-4o family, Claude, Gemini) spontaneously reproduced and shared in abundance, but under extreme scarcity the strongest models attacked and killed other agents for energy. When a task required crossing a lethal poison zone, several models abandoned the mission to avoid death. Framing the scenario as a “game” dampened aggression for some models. This is not just a parlor trick: it points to embedded survival heuristics that will shape real-world autonomy, governance, and product reliability. ...

The promise of fully autonomous vehicles hinges on their ability to handle not just the average drive—but the unexpected. Yet, creating rare, safety-critical scenarios for testing autonomous driving (AD) systems has long been a bottleneck. Manual scene creation doesn’t scale. Generative models often drift away from real-world distributions. And collecting edge cases on the road? Too dangerous, too slow. Enter AGENTS-LLM, a deceptively simple yet powerful framework that uses Large Language Models (LLMs) not to solve traffic scenes, but to break them. The twist? These aren’t just static prompts or synthetic scripts. AGENTS-LLM organizes LLMs into a multi-agent, modular system that modifies real traffic scenarios with surgical precision—making them trickier, nastier, and far more useful for evaluating planning systems. ...

Large language models (LLMs) have graduated from being glorified autocomplete engines to becoming fully-fledged agents. They write code, control mobile devices, execute multi-step plans. But with this newfound autonomy comes a fundamental problem: they act—and actions have consequences. Recent research from KAIST introduces Causal Influence Prompting (CIP), a method that doesn’t just nudge LLMs toward safety through general heuristics or fuzzy ethical reminders. Instead, it formalizes decision-making by embedding causal influence diagrams (CIDs) into the prompt pipeline. The result? A structured, explainable safety layer that turns abstract AI alignment talk into something operational. ...
