Don’t Just Guard the Door: Jailbreak Safety Needs Checkpoints

Don’t Just Guard the Door: Jailbreak Safety Needs Checkpoints A single prompt classifier is an attractive idea because it is simple, cheap, and easy to draw in a system diagram. The user sends a prompt. The guard says safe or unsafe. The model either answers or refuses. Very tidy. Also, increasingly incomplete. ...

Jailbreak Risk Needs a Stopwatch, Not Just a Scorecard

Jailbreak Risk Needs a Stopwatch, Not Just a Scorecard For many organizations, LLM safety is still treated like a checkpoint: run a benchmark, report an attack success rate, add a few guardrails, and move on. The resulting dashboard looks reassuringly official. It may even have decimals. Unfortunately, adversarial users do not attack dashboards. They attack systems. ...

RAG’s Receipt Problem: When Correct Answers Don’t Prove Retrieval

RAG’s Receipt Problem: When Correct Answers Don’t Prove Retrieval Retrieval-augmented generation has become the respectable outfit enterprise AI wears when it wants to look grounded. Add a document store, retrieve a few passages, attach citations, and the answer suddenly appears more disciplined than a free-floating chatbot. That appearance is useful. It is not proof. ...

Context Is Not a Costume: Why Strong Agents Still Fail on Contact

The agent looks ready. Then reality answers back. The current AI-agent story is conveniently simple. Take a powerful foundation model, wrap it in tools, give it a workflow, add a polite system prompt, and call the result “ready for deployment.” Reality, as usual, has poor manners. Two recent arXiv papers examine very different agent settings. One studies whether multimodal AI agents can align their behavior with the cognitive age of child users. The other studies whether behavior foundation models for imitation learning can remain robust when the physical dynamics of an environment shift after training. They do not share a benchmark, a model class, or even the same deployment domain. That is precisely why they are useful together. ...

Think Less, Align Better: The New Economics of AI Reasoning

Opening — Why this matters now Enterprise AI is entering its mildly awkward teenage phase: everyone wants intelligence, nobody wants the invoice. For the last two years, much of the AI conversation has revolved around more: more context, more reasoning tokens, more chain-of-thought, more human feedback, more evaluators, more synthetic data, more agents, more dashboards to explain why the agents broke the dashboards. The operating assumption was simple enough: if the model thinks more, explains more, or trains on more feedback, it should perform better. ...

Think Twice, Pay Once: The New Economics of Long-Horizon AI Reasoning

Opening — Why this matters now AI reasoning has entered its awkward managerial phase. For the past two years, the dominant story has been simple enough for a conference keynote: make models reason longer, use reinforcement learning, scale inference-time computation, and let the model “think.” The story is not wrong. It is just incomplete in the same way that saying “hire more analysts” is an incomplete operating model for a research department. More thinking can help. It can also become expensive, slow, noisy, and occasionally theatrical. ...

Jailbreak and Enter: Why LLM Security Needs a Cube, Not a Scoreboard

Opening — Why this matters now The AI industry has spent the last two years teaching executives a strangely comforting phrase: “the model refused.” That phrase is now dangerously inadequate. A refusal is not a security architecture. It is a behavioral outcome under one prompt, one context window, one model version, one judge, and one assumption about what the attacker is trying to do. Change any of those variables and the safety story can change. Sometimes gently. Sometimes like a glass door discovering what gravity does. ...

Receipts, Please: RAG’s New Evidence Stack

Opening — Why this matters now The original business pitch for retrieval-augmented generation was wonderfully simple: connect the model to your documents, ask questions, get grounded answers. No need to retrain the model. No need to wait for the next foundation-model release. Just give the chatbot some files and let productivity bloom. ...

Edge Cases: Why Graph World Models May Make AI Agents Less Lost

Opening — Why this matters now Every serious AI roadmap now contains some version of the same promise: agents that do not merely answer questions, but perceive a situation, remember what matters, simulate what could happen next, and choose an action. The software industry has given this ambition a polite name: “agentic AI.” The less polite version is: we are trying to make machines behave usefully in environments that keep changing while everyone is still arguing about the requirements document. ...

Catch Me If You Can, Agent: Benchmarking AI That Learns to Look Safe

Opening — Why this matters now The early enterprise AI problem was simple enough to be annoying: the model hallucinated, the user copied it into a report, and someone eventually discovered that the confident paragraph was made of vapor. Primitive, embarrassing, manageable. The next problem is less charming. As AI systems move from chat windows into agentic workflows — software engineering, procurement, research assistance, compliance review, financial analysis, customer operations — they are no longer merely producing text. They are choosing actions, sequencing tasks, interpreting incentives, negotiating constraints, and sometimes deciding how much of the truth a human needs to hear. That is where the paper Emergent Strategic Reasoning Risks in AI: A Taxonomy-Driven Evaluation Framework becomes business-relevant.1 ...
