Medical Agent Controller

Quentin Marquet, Ouafae Moudni, Shakthivel Murugavel, Xavier Charles, Elise Racine

The Medical Agent Controller (MAC) is a multi-agent governance framework designed to safeguard AI-powered medical chatbots by intercepting unsafe recommendations in real time.

It employs a dual-phase approach, using red-team simulations during testing and a controller agent during production to monitor and intervene when necessary.

By integrating advanced medical knowledge and adversarial testing, MAC enhances patient safety and provides actionable feedback for continuous improvement in medical AI systems.

Strengths:

-Comprehensive Literature Review: The paper demonstrates a strong understanding of existing literature, particularly around AI hallucinations, biases, and medical AI risks.

-Novel Methodology: The multi-agent controller framework is innovative and addresses a critical gap in regulating medical AI chatbots.

-Clear Methodology: The experimental design and methodology are well-documented, with detailed explanations of the red team and controller agents.

-Real-World Impact: The framework was tested in a controlled production environment, demonstrating its practical applicability and low-latency performance.

-Societal Relevance: The paper effectively connects AI safety challenges to real-world implications in healthcare, such as patient safety and ethical concerns.

Areas for Improvement:

-Limitations and Negative Consequences: The paper does not explicitly discuss the limitations of the framework or potential negative consequences of its implementation. Adding this would strengthen the analysis.

-Conclusion Expansion: The conclusion could be expanded to include more actionable recommendations and future research directions, particularly around scalability and cross-cultural applicability.

Suggestions for Future Work:

-Conduct larger-scale experiments to validate the findings and improve generalizability.

-Explore cross-disciplinary approaches (e.g., ethics, policy) to broaden the societal impact of the research.

-Investigate the framework’s performance in diverse cultural and regulatory contexts.

Thank you for submitting your work on ‘Medical Agent Controller’ - it was interesting to read. Please see below for some feedback on your project:

1. Strengths of your proposal/ project:

- The paper is well referenced and well structured

- This is a topical area, which is in need of more attention from researchers and people in industry

- This appears to be a novel contribution

2. Areas for improvement

- This paper needs to more strongly delineate between ‘AI-driven medical chatbots’ - which are regulated as medical devices in the UK (which isn’t mentioned), and general purpose AI models that aren’t regulated as medical devices. Could you expand upon why ‘many health chatbots remain unclassified as medical devices’? (p.2).

- It is good that you provide a threat model. This could be more fleshed out (e.g., with a Theory of Change, and/or examples), and it would be helpful if you outlined the implications of these threats. E.g., what is the impact/ implication of bias and discrimination?

- More specifics would be better re: methods - e.g., ‘Through thousands of simulated conversations orchestrated by the Red Team Agent’ - how many thousand? What conversations - can you provide an example?

- It would be helpful to understand a bit more about the background of MAC - has it been used elsewhere, etc?

Cecilia Elena Tilli

Well written and clear. I like the pragmatic approach of designing a tool that seems like it could be combined with an arbitrary medical chatbot.

I would be even more excited if the project tried some more original approach - I feel a bit like you are playing it safe, sticking to rather established methods and well-known challenges. That said, the problem is real and important and the project seems well executed.

Local Learning Coefficients Predict Developmental Milestones During Group Relative Policy Optimization

In this work, we investigate the emergence of capabilities in reinforcement learning (RL) by framing them as developmental phase transitions. We propose that the individual components of the reward function can serve as direct observables for these transitions, avoiding the need for complex, derived metrics. To test this, we trained a language model on an arithmetic task using Group Relative Policy Optimization (GRPO) and analyzed its learning trajectory with the Local Learning Coefficient (LLC) from Singular Learning Theory. Our findings show a strong qualitative correlation between spikes in the LLC—indicating a phase transition—and significant shifts in the model's behavior, as reflected by changes in specific reward components for correctness and conciseness. This demonstrates a more direct and scalable method for monitoring capability acquisition, offering a valuable proof-of-concept for developmental interpretability and AI safety. To facilitate reproducibility, we make our code available at \url{github.com/ilijalichkovski/apart-physics}.

AI agentic system epidemiology

As AI systems scale into decentralized, multi-agent deployments, emergent vulnerabilities challenge our ability to evaluate and manage systemic risks.

In this work, we adapt classical epidemiological modeling (specifically SEIR compartment models) to model adversarial behavior propagation in AI agents.

By solving systems of ODEs describing the systems with physics-informed neural networks (PINNs), we analyze stable and unstable equilibria, bifurcation points, and the effectiveness of interventions.

We estimate parameters from real-world data (e.g., adversarial success rates, detection latency, patching delays) and simulate attack propagation scenarios across 8 sectors (enterprise, retail, trading, development, customer service, academia, medical, and critical infrastructure AI tools).

Our results demonstrate how agent population dynamics interact with architectural and policy design interventions to stabilize the system.

This framework bridges concepts from dynamical systems and cybersecurity to offer a proactive, quantitative toolbox on AI safety.

We argue that epidemic-style monitoring and tools grounded in interpretable, physics-aligned dynamics can serve as early warning systems for cascading AI agentic failures.

Momentum–Point-Perplexity Mechanics in Large Language Models

This work analyzes the hidden states of twenty different open-source transformer language models, ranging from small to medium size and covering five major architectures. The key discovery is that these models show signs of "energy conservation" during inference—meaning a certain measure combining changes in hidden states and token unpredictability stays almost constant as the model processes text.

The authors developed a new framework inspired by physics to jointly analyze how hidden states and prediction confidence evolve over time. They propose that transformers' behavior can be understood as following certain mechanical principles, much like how physical systems follow rules like conservation of energy.

Their experiments show that this conserved quantity varies very little between tokens, especially in untrained (random-weight) models, where it's extremely stable. In pre-trained models, the average energy drops more due to training, but there are larger relative fluctuations from token to token.

They also introduce a new method, based on this framework, for controlling transformer outputs by "steering" the hidden states. This method achieves good results—producing completions rated as higher in semantic quality, while still maintaining the same kind of energy stability.

Overall, the findings suggest that viewing transformer models through the lens of physical mechanics gives new, principled ways to interpret and control their behavior. It also highlights a key difference: random models behave more like balanced systems, while trained models make quicker, more decisive state changes at the cost of less precise energy conservation.
