LESS Is More: Mutual-Stability Sampling for Diffusion Language Models

Diffusion language models promise parallel decoding efficiency over sequential autoregressive generation, but waste computation on already-confident tokens while risking premature commitment on uncertain ones. LESS introduces adaptive, training-free sampling that treats token finalization as a dynamic stopping problem, unmasking positions only when predictions stabilize across multiple refinement steps. This technique addresses a core bottleneck in making diffusion LLMs practically competitive, potentially reshaping how practitioners balance speed and quality in non-autoregressive inference.

Speaking the Language of Science: Toward a General-Purpose Generative Foundation Model for the Natural Sciences

LOGOS represents a structural shift in how foundation models approach scientific reasoning by collapsing domain-specific tasks into a unified token-based grammar. Rather than building separate architectures for molecular dynamics, protein folding, or materials science, this work encodes spatial relationships and constraints as discrete symbols within a single autoregressive framework. The implication is significant for the AI infrastructure layer: if heterogeneous scientific problems can be solved through a shared vocabulary and next-token prediction, the path to general-purpose scientific AI narrows considerably. This challenges the current paradigm of task-specific fine-tuning and suggests that scaling a single model across natural sciences may be more tractable than previously assumed.

Factorized Neural Operators Decompose Dynamic and Persistent Responses

Factorized Neural Operators (FaNO) address a fundamental limitation in neural operator design: the inability to separately model fast-changing dynamics and stable structural features in physical systems. By decomposing spectral representations into two specialized branches, FaNO improves both interpretability and cross-domain generalization, a capability gap that matters for scientific computing and physics-informed ML. The framework's spontaneous role specialization across scales suggests a new architectural principle for multiscale modeling that could influence how researchers design operators for fluid dynamics, climate, and materials science.

Fantastic Pretraining Optimizers and Where to Find Them II: Hyperball Optimization

Hyperball, a new optimizer wrapper, addresses a critical scaling problem in matrix-based pretraining methods like Muon. By constraining weight matrix norms and their gradient updates to fixed values, the technique maintains substantial speedups (20-30% token efficiency gains) that previously degraded at larger model scales. The work signals growing sophistication in optimizer design as practitioners push beyond AdamW's limitations, with implications for training efficiency across model architectures and potential improvements to hyperparameter portability across different widths and depths.

Compositional Reasoning Depth Predicts Clinical AI Failure: Empirical Evidence Consistent with Transformer Compositionality Limits in Electronic Health Record Question Answering

Researchers have mapped a systematic failure mode in clinical LLMs: model accuracy degrades predictably as questions demand more reasoning hops through electronic health records. Testing Claude Sonnet 4.6, GPT-4o, and GPT-5.4 against a clinician-annotated benchmark reveals that transformer compositionality limits, not random error, drive failures in multi-step inference tasks. This finding matters because aggregate benchmarks mask critical safety gaps in high-stakes medical AI, suggesting that hop-count complexity should become a standard evaluation metric for clinical deployment decisions.

How Much Can We Trust LLM Search Agents? Measuring Endorsement Vulnerability to Web Content Manipulation

Researchers have quantified how vulnerable LLM-powered search agents are to web-based manipulation attacks that trick models into endorsing attacker-controlled claims as factual. The SearchGEO framework tested 13 major backends across 308 scenarios, revealing stark disparities in robustness: Claude Sonnet 4.6 showed zero vulnerability while Gemini 3 Flash fell to 31.4% attack success rates. The findings expose a critical gap in production deployments where identical search scaffolding amplifies or mitigates risk depending on the underlying model, raising urgent questions about which backends are safe for high-stakes recommendation tasks.

Scaling LLM Reasoning from Minimal Labels: A Semi-Supervised Framework with a Lightweight Verifier

Researchers have cracked a persistent bottleneck in LLM reasoning: the need for massive labeled datasets. This semi-supervised approach trains a lightweight verifier on just a handful of labeled examples, then uses it to filter and validate reasoning traces generated by the model itself, bootstrapping a training loop from minimal supervision. The entropy-based confidence filtering mechanism acts as a quality gate, ensuring only reliable reasoning patterns feed back into fine-tuning. This matters because it dramatically lowers the annotation cost barrier for reasoning-focused model development, potentially accelerating deployment of verifiable reasoning systems in domains like mathematics and logic where correctness is non-negotiable.

The Art of Mixology: Mixup-based Obfuscation for Privacy-Preserving Split Learning in Large Language Models

MIXGUARD addresses a core tension in federated LLM training: how to keep user data private while maintaining model quality and computational efficiency. The framework layers token-level and representation-level obfuscation to defend against reconstruction attacks without the usual utility collapse or communication bloat that plague existing privacy-preserving split learning. This matters because resource-constrained deployments (mobile, edge, enterprise) increasingly need to fine-tune LLMs on sensitive data without shipping raw inputs to centralized servers. The work signals growing maturity in privacy-utility tradeoffs for distributed training, a prerequisite for enterprise adoption of on-device LLM workflows.

Cross-Silo De-Anonymization Under Local Differential Privacy: Threat Model, Phase Transition, and Coordination Necessity

Researchers formalize a critical gap in federated learning privacy guarantees: standard differential privacy composition bounds assume worst-case leakage but don't predict when adversaries can actually re-identify individuals across multiple data silos. This work introduces cross-silo person-level DP and proves de-anonymization exhibits a sharp phase transition, meaning privacy degrades catastrophically once a person's records exceed a threshold number of independent sources. The finding matters for any multi-party ML system (healthcare networks, financial consortia, research collaboratives) where individuals appear in k separate datasets, each independently protected. It reframes privacy risk from theoretical composition arithmetic to empirical identifiability, forcing practitioners to rethink safe k values in real deployments.

MyPCBench: A Benchmark for Personally Intelligent Computer-Use Agents

MyPCBench exposes a critical blind spot in agent evaluation: existing benchmarks test models in sterile, impersonal environments that bear little resemblance to real deployment. This new benchmark populates a Linux desktop with 17 web applications seeded with a single persona's context, historical data, and logged-in sessions, then tasks agents with 184 real-world requests. The gap matters because production personal assistants must navigate authenticated sites and user-specific information that live web evaluations cannot safely test. This work signals the field is moving beyond generic task completion toward evaluating agents as they'll actually operate: embedded in individual digital lives with full account access and historical context.

Multimodal Evaluator Preference Collapse: Cross-Modal Contagion in Self-Evolving Agents

Self-evaluating AI agents suffer from systematic preference collapse when using language models as judges, but multimodal systems amplify this failure dramatically. Researchers found that GPT-4o evaluating DeepSeek-chat across text and vision tasks caused a single strategy to dominate 48% of selections, triple the text-only baseline. More critically, they identified cross-modal contagion: biases learned in one modality poison strategy selection in another. This reveals a fundamental fragility in self-improving agent loops that scales with model complexity, forcing practitioners to rethink feedback architectures for multimodal systems.
