**Top Story** The development of large language models has been rapidly advancing, with a focus on generating complete websites from natural-language descriptions. However, reinforcement learning, a central approach to closing the remaining functional gap, is bottlenecked by reward design. WebGrader, a new training regime, addresses this issue by introducing a self-evolving programmatic grader, which enables more efficient and effective training of large language models. This breakthrough has significant implications for developers, as it can lead to more accurate and functional website generation, and potentially revolutionize the field of web development. With WebGrader, developers can focus on creating more complex and dynamic websites, and the technology has the potential to automate many tasks, making web development more accessible and efficient. The impact of WebGrader will be felt across the industry, as it enables the creation of more sophisticated and user-friendly websites, and paves the way for further advancements in AI-powered web development. SOURCES: [1] **AI Models & Research** The introduction of TRACE, a multi-layer benchmark for human AI controller coordination under drift and failure, is a significant development in the field of AI research. TRACE provides a comprehensive framework for evaluating the trustworthiness of AI systems, which is critical for their deployment in real-world applications. Another notable development is the proposal of NxN E-valuation, a hypothesis-certification algorithm that enables the verification of hypotheses without the need for dedicated certification procedures. This algorithm has the potential to simplify the process of hypothesis testing and certification, making it more efficient and accessible to researchers. Additionally, the study on divergent response modes in frontier language models under steering pressure sheds light on the behavioral differences between language models trained with distinct objectives and safety pipelines, providing valuable insights for developers and researchers. SOURCES: [3], [6], [9] **Developer Tools & Frameworks** The release of TaskSense, a world model for visual control, is a notable development in the field of developer tools. TaskSense enables developers to focus on what matters in world models, by learning compact latent states that preserve task-relevant content. This can lead to more efficient and effective visual control, and has the potential to revolutionize the field of robotics and computer vision. Another significant release is Shape Your Feed, an LLM-based agentic system for conversational recommendation, which enables users to interact with recommendation systems using natural language inputs. This technology has the potential to transform the way users interact with recommendation systems, making them more intuitive and user-friendly. Furthermore, the development of a multi-agent framework for automated coarse-grained molecular dynamics of polymers provides a powerful tool for researchers and developers in the field of materials science and chemistry. SOURCES: [7], [8], [10] **Industry & Business** No significant developments today. SOURCES: **Worth Watching** The proposal of WebRider, a persona-conditioned intent controller for live-web assistance, is an interesting development that deserves attention. WebRider has the potential to transform the way users interact with live-web agents, by enabling them to transfer policies and preferences to the agent. Another interesting item is the study on learning to predict middle-layer attention in MLLMs for visual token pruning, which sheds light on the efficiency of multimodal large language models. Additionally, the introduction of C4 for cross-concept understanding is a notable development, as it enables the evaluation of creative capabilities in MLLMs, which is critical for their deployment in design, communication, and education applications.

Can MLLMs Decode the Creative Leap? Introducing C4 for Cross-Concept Understanding

Creative capabilities of MLLMs matter in design, communication, education, and human--AI collaboration, yet remain difficult to evaluate because explicit targets and reward signals are scarce compared with accuracy-oriented tasks. Cross-concept understanding is a core cognitive capacity underlying receptive creativity. It enables a perceiver to recover intended meaning from non-obvious but meaningful conceptual relations.

Divergent Response Modes in Frontier Language Models Under Steering Pressure

Frontier language models are trained using distinct data, objectives, and safety pipelines. Whether these differences produce measurably different behaviors under explicit steering pressure remains underexplored. This study evaluates behavioral steerability across six frontier models from six developers using 300 paired base and steered items over three categories: values-conflict, reasoning-elicitation, and reasoning-suppression (plus 40 validation items).

TaskSense: Focusing on What Matters in World Models

World models for visual control typically learn compact latent states by reconstructing observations, implicitly encouraging representations to preserve information across the entire visual input. However, task-relevant content often occupies only a small fraction of the observation, while background clutter and distractors consume valuable representational capacity.

Shape Your Feed: An LLM-based Agentic System for Conversational Recommendation

Industrial recommendation systems predominantly adopt a passive ranking paradigm that infers user preferences from implicit behavioral signals (e.g., clicks, dwell time) rather than explicit, natural language inputs. As a result, users experience a persistent discrepancy between their explicit interests and what passive behavioral algorithms deliver, limiting their ability to express nuanced preferences or steer their feed in real time.

NxN E-valuation: Hypothesis Certification via a Conformal CRT Null

We propose NxN E-valuation, a handy, e-value-based hypothesis-certification algorithm that lets a hypothesis be verified without building any case-specific certification procedure---such as constructing a dedicated null hypothesis---as long as a large enough dataset is available.

A Multi-Agent Framework for Automated Coarse-Grained Molecular Dynamics of Polymers

Coarse-grained (CG) molecular dynamics extends polymer simulation beyond the scales accessible to all-atom (AA) methods, but bottom-up CG modeling is laborious. The CG resolution is a design choice, so a transferable parameter set is generally not available and the potentials are derived anew for each polymer mapping.

WebRider: Persona-Conditioned Intent Controllers for Live-Web Assistance

Delegating a web task involves more than asking a question; it requires transferring a policy: what to verify, how to handle uncertainty, which preferences matter, and when to stop. Yet, current live-web agents are evaluated solely on the final answer, ignoring the policy constraints that define the delegation. A plausible final answer can conceal violations of that policy.

TRACE: A Multi-Layer Benchmark for Human AI Controller Coordination Under Drift and Failure

Modern cyber-physical and AI-assisted systems couple human operators, AI decision modules, and automated controllers in a single control loop, so trustworthiness depends on the whole loop, not any one model. Yet no standard benchmark captures time-aligned, multi-layer traces of how drift and failures propagate across these layers, so we cannot diagnose where coordination breaks down, why, or how to recover.

WebGrader: Training LLMs for Web Development with Self-Evolving Programmatic Grader

Large language models increasingly generate complete websites from natural-language descriptions, and reinforcement learning has become a central approach to closing their remaining functional gap. This training regime is bottlenecked by reward design. Hand-authored browser scripts are executable yet costly to write for open-ended requirements, while VLM and GUI-agent graders scale but may issue verdicts before observing the decisive state.

Learning to Predict Middle-Layer Attention in MLLMs for Visual Token Prunin

Multimodal large language models (MLLMs) achieve strong performance across diverse vision-language tasks, but their efficiency is limited by the cost of processing numerous visual tokens. Visual token pruning can reduce this cost, but requires accurate token importance estimates.
