**Top Story** The FDA has cleared the first software as a medical device with a patient-facing large language model (LLM), marking a significant milestone for clinical AI developers. This decision opens up a pathway for the development of AI-powered medical devices that can interact directly with patients. The clearance is a result of the growing recognition of the potential of AI in healthcare, and it is expected to have a major impact on the development of AI-based medical devices. This development matters because it highlights the increasing importance of AI in healthcare and the need for developers to create AI systems that are safe, effective, and transparent. As AI continues to play a larger role in healthcare, developers will need to ensure that their systems meet the highest standards of safety and efficacy, and this clearance is an important step in that direction. The implications of this decision are far-reaching, and it is likely to lead to the development of more AI-powered medical devices that can improve patient outcomes. **AI Models & Research** The introduction of interventional grounding audits is a significant development in the field of AI research. This black-box, step-level test of premise dependency is designed to evaluate the logical soundness of large language models' chain-of-thought reasoning. By using predicate substitution, this test can help developers identify potential flaws in their models' reasoning processes. Another important development is the proposal of LAPO, a self-generated process-supervision method for multi-turn search reasoning. This method can help distinguish between useful, redundant, and harmful intermediate interactions, which is essential for developing more effective AI systems. Additionally, the development of AI-native insurance frameworks for agentic AI is a crucial step towards creating more robust and reliable AI systems. This framework can help underwrite and automate insurance policies for autonomous AI systems, which is essential for their widespread adoption. **Developer Tools & Frameworks** The release of the Harness Handbook is a significant development for developers working with evolving agent harnesses. This handbook provides a comprehensive guide to making harnesses readable, navigable, and editable, which is essential for developing more effective AI systems. With this handbook, developers can create harnesses that are more flexible and adaptable, which can help improve the overall performance of their AI systems. Another notable release is the development of active shared context graphs for human-AI team science. This framework can help facilitate more effective collaboration between humans and AI systems, which is essential for tackling complex scientific problems. By using this framework, developers can create AI systems that are more transparent and explainable, which can help build trust and improve overall performance. **Industry & Business** The FDA's clearance of the first software as a medical device with a patient-facing LLM is a significant development for the healthcare industry. This decision is expected to have a major impact on the development of AI-powered medical devices, and it is likely to lead to increased investment in this area. The development of AI-native insurance frameworks for agentic AI is also a significant development for the insurance industry. This framework can help underwrite and automate insurance policies for autonomous AI systems, which is essential for their widespread adoption. As AI continues to play a larger role in various industries, the development of more robust and reliable AI systems will be crucial for their success. **Worth Watching** The study on AI advice suppressing people's willingness to say "I don't know" is a fascinating development that highlights the potential risks of over-reliance on AI systems. This study shows that even when AI advice is wrong, people may still be less likely to say "I don't know", which can have significant implications for decision-making and critical thinking. The development of probabilistic extensions of neuro-symbolic AGI robots is also an interesting area of research that has the potential to overcome the limitations of purely neural systems. By combining neural learning and symbolic reasoning, these robots can provide more transparent and explainable decision-making processes, which can help build trust and improve overall performance. Additionally, the set-shifting behavioral test for harnessed agents is a useful tool for evaluating the adaptability of AI systems, which is essential for developing more effective and reliable AI systems.

Interventional Grounding Audits: Black-Box Premise-Dependency Tests for LLM Chain-of-Thought via Predicate Substitution

Large language models produce chain-of-thought (CoT) reasoning that appears logically sound yet may not genuinely depend on its stated premises. We introduce interventional grounding audits, a black-box, step-level test of premise dependency: we intervene on a single premise by substituting its target predicate with a fresh symbol, re-run the model, and check whether each reasoning step's normalized conclusion (canonical predicate form) changes.

Networked Intelligence: Active Shared Context Graphs for Human-AI Team Science

Most AI-for-science systems focus on scaling a single reasoning process through better models, larger context windows, long-horizon agentic execution, or digital co-scientists working with one principal user. However, challenging scientific problems are rarely solved by one reasoner alone. They are solved by teams whose members bring different priors, experimental backgrounds, tacit knowledge, and domain-trained intuitions.

LAPO: Leave-One-Turn Attribution for Self-Generated Process Rewards in Multi-Turn Search Reasoning

Reinforcement learning for multi-turn search reasoning typically relies on terminal outcome rewards, which cannot distinguish useful, redundant, and harmful intermediate interactions. We propose LAPO, a self-generated process-supervision method based on backward leave-one-turn attribution. For each search turn, LAPO replaces the turn and its retrieval observation with a fixed [DELETE] placeholder and measures the resulting change in the current policy's mean log-likelihood of the gold answer.

AI advice suppresses people's willingness to say "I don't know", even when the advice is wrong and accuracy is incentivized

Knowing when to say "I don't know" is fundamental to human judgment, yet AI assistants offer a fluent answer to almost any question. In five experiments (N = 3,132; four preregistered, one direct replication), participants answered difficult questions and could always decline to respond. We engineered the questions so that AI advice was wrong, separating AI use from its accuracy.

Harness Handbook: Making Evolving Agent Harnesses Readable,Navigable, and Editable

The capability of a modern AI agent depends not only on its foundation model but also on its harness, which constructs prompts, manages state, invokes tools, and coordinates execution. As models, APIs, environments, and requirements evolve, the harness must be continually modified. Before such a change can be made, a developer or coding agent must identify all code locations that implement the target behavior.

AI-Native Insurance for Agentic AI: Pricing, Underwriting, and End-to-End Automation

Agentic AI introduces new insurance challenges because autonomous AI systems can make decisions, invoke tools, modify external environments, and interact with third-party services. This paper develops an AI-native mathematical framework for underwriting, pricing, and contract design for agentic AI deployments. A deployment is represented by a risk state that captures autonomy level, operational authority, permission exposure, governance maturity, and dependency concentration.

Learning Safe Agent Behaviour from Human Preferences and Justifications via World Models

We address the problem of safely training an agent policy and deploying a good and safe policy, in settings where the environment dynamics are unknown and no suitable reward function is available. In the context of safety-critical environments, we consider traditional reinforcement learning impractical and resort to the resource of human input. We introduce DROPJ, a human-centred method for both safe training and deployment.

Set-shifting Behavioral Test for Harnessed Agents

What happens to an LLM agent's tool choice when the reliable tool silently changes within an ongoing session? We borrow set-shifting from cognitive psychology to study how well agents adapt to hidden reliability shifts. Our benchmark mounts tool-skill libraries with redundancies, where many tools solve the same task but differ in hidden reliability. In our evaluation framework, a branched schedule shifts the reliable tool group at hidden boundaries and pairs every shift with a no-shift control.

Probabilistic Extension of Neuro-Symbolic AGI Robots based on Belnap's Typed Intensional FOL

Neuro-symbolic AI based on $IFOL_B$ is a way to combine neural learning and symbolic reasoning to overcome limitations of purely neural systems (like lack of interpretability and logical structure) with formal logical machinery for self-reference. In this paper we expand the cognitive power of $IFOL_B$ by using the probability computation for the currently unknown sentences, based on Nilsson's probability structure for the $IFOL_B$.
