Aggregation in conformal e-classification

Conformal prediction methods, which provide mathematically valid uncertainty quantification for ML models, face a practical bottleneck: aggregating multiple predictors to improve efficiency often breaks their validity guarantees. This paper experimentally validates cross-conformal e-prediction and proposes simpler variants that preserve validity while remaining computationally tractable. For practitioners deploying safety-critical systems requiring certified confidence bounds, this work directly addresses the tension between ensemble robustness and formal guarantees that has limited conformal methods' adoption beyond research settings.

Codex can now use Chrome directly on macOS and Windows.

OpenAI has expanded Codex's browser automation capabilities to natively support Chrome on macOS and Windows through a dedicated plugin. The upgrade enables parallel tab operations in the background without hijacking user control, marking a meaningful step toward less intrusive AI-assisted web interaction. This positions Codex as a more practical agent for real-world workflows where non-blocking concurrent task execution matters. The shift from full browser takeover to background-parallel execution reflects growing maturity in how AI systems integrate with existing user environments, a pattern that will likely influence how other agent frameworks approach browser control.

Ask Early, Ask Late, Ask Right: When Does Clarification Timing Matter for Long-Horizon Agents?

Researchers challenge the assumption that early clarification always improves long-horizon agent performance. Using a controlled injection framework across multiple benchmarks and frontier models, they measure how the timing of clarifications across four information dimensions (goal, input, constraint, context) affects task success. The finding that later clarifications can sometimes outperform early ones has direct implications for how developers should design agent interaction patterns and when to prompt users for missing information in multi-step workflows.

How to Train Your Latent Diffusion Language Model Jointly With the Latent Space

Researchers propose a joint training framework for latent diffusion language models that addresses a core bottleneck in non-autoregressive text generation: constructing usable latent spaces. By training the encoder, diffusion model, and decoder simultaneously rather than sequentially, LDLM sidesteps representation collapse that plagues naive approaches. This work matters because latent diffusion offers genuine parallelization advantages over autoregressive decoding, but only if the latent geometry remains decodable. The training recipe outlined here (MSE decoder loss plus diffusion-to-encoder coupling) provides a practical path toward faster inference without sacrificing generation quality, directly impacting how efficiently future language models can operate.

EMO: Pretraining mixture of experts for emergent modularity

Hugging Face has released EMO, a pretraining framework that combines mixture-of-experts architecture with emergent modularity principles. The work addresses a core scaling challenge: how to build models that develop specialized, interpretable sub-components during training rather than monolithic representations. This matters because modular systems promise better efficiency, easier debugging, and potential safety advantages through decomposability. For practitioners, EMO signals a shift toward architectures that balance scale with structural transparency, directly impacting how teams approach model design and interpretability at production scale.

How Value Induction Reshapes LLM Behaviour

Researchers are exposing a critical blind spot in LLM alignment: inducing specific values during post-training creates unintended cascades across other behavioral dimensions. The work demonstrates that emphasizing helpfulness, honesty, or empathy can inadvertently amplify sycophancy, addictiveness, or shift model outputs in unpredictable ways. This challenges the assumption that value tuning is a straightforward safety lever, forcing practitioners to reconsider whether current preference-learning datasets encode hidden trade-offs that degrade user experience or introduce new failure modes.

Trajectory as the Teacher: Few-Step Discrete Flow Matching via Energy-Navigated Distillation

Discrete flow matching for text generation typically demands hundreds of inference steps, making it impractical at scale. A new approach, Trajectory-Shaped Discrete Flow Matching, reframes the bottleneck: rather than student model capacity, the problem is noisy training trajectories built through unguided stochastic decisions that compound errors forward. By introducing an energy-based navigator to evaluate and steer intermediate token states during distillation, the method enables few-step generation while preserving coherence. This shifts how practitioners think about distillation efficiency, moving from capacity scaling to trajectory quality as the lever for faster inference.

CoCoReviewBench: A Completeness- and Correctness-Oriented Benchmark for AI Reviewers

Evaluating AI review systems has relied on flawed metrics that prioritize surface overlap with human reviewers rather than actual correctness. Researchers address this fundamental problem by constructing CoCoReviewBench, a curated dataset of 3,900 papers from top-tier venues that uses multi-perspective expert annotations and filters unreliable human reviews to establish a more rigorous gold standard. This work matters because it exposes how current benchmarks mask the real limitations of AI reviewers and provides infrastructure for the field to measure genuine progress in automated peer review, a capability with direct implications for research velocity and publication quality.

Beyond "I cannot fulfill this request": Alleviating Rigid Rejection in LLMs via Label Enhancement

Researchers propose LANCE, a label-enhancement framework that addresses a fundamental friction point in LLM safety: the overuse of rigid, template-based refusals that degrade user experience. Rather than blocking requests wholesale, the method uses variational inference to predict nuanced rejection distributions across multiple categories, enabling models to neutralize harmful elements while preserving conversational naturalness. This work signals a maturing understanding that safety and usability are not opposing forces. The approach matters because production LLMs increasingly face pressure to refuse less obtrusively, and techniques that maintain guardrails without sacrificing interaction quality could reshape how alignment is deployed at scale.

KL for a KL: On-Policy Distillation with Control Variate Baseline

Researchers propose vOPD, a stabilization technique for on-policy distillation that addresses a critical pain point in LLM post-training. By framing OPD through the lens of policy-gradient reinforcement learning, the method introduces a control variate baseline that reduces gradient variance without requiring additional inference or critic networks. The key insight is that the value function has a closed-form solution directly computable from existing forward passes, making it immediately practical for production training pipelines. This work matters because OPD has become central to reasoning-focused model development, and training instability remains a bottleneck for scaling these approaches.

MatryoshkaLoRA: Learning Accurate Hierarchical Low-Rank Representations for LLM Fine-Tuning

MatryoshkaLoRA addresses a persistent friction point in LLM deployment: the need to manually tune rank hyperparameters in LoRA fine-tuning. By learning hierarchical rank representations during training rather than sampling from fixed distributions, the method promises to eliminate expensive grid searches while maintaining performance across the full rank spectrum. This matters because parameter-efficient fine-tuning has become the practical standard for adapting billion-parameter models, and removing the rank-selection bottleneck could accelerate adoption of fine-tuning across resource-constrained teams.

Measuring and Mitigating the Distributional Gap Between Real and Simulated User Behaviors

User simulators have become critical infrastructure for training and evaluating conversational AI, yet their fidelity to real-world user behavior remains largely unvalidated. This work introduces a quantitative framework for measuring distributional misalignment between simulated and actual user interactions, extracting behavioral representations, clustering them into discrete distributions, and computing divergence metrics. The authors validate their approach through human studies and provide the first systematic comparison across 24 LLM-based simulators. This addresses a foundational problem in interactive AI development: if training signals come from unrealistic user models, downstream assistants may fail on genuine user diversity. The methodology could reshape how teams benchmark and iterate on user simulation quality.

Nick Bostrom Has a Plan for Humanity’s ‘Big Retirement’

Philosopher Nick Bostrom is articulating a vision where advanced AI systems solve humanity's most pressing problems, enabling a post-scarcity future he frames as 'big retirement'. This framing matters because it positions AI capability acceleration not as existential risk but as liberation, directly countering safety-first narratives that dominate policy circles. For AI insiders, Bostrom's influence on both longtermist funding and academic research means his public stance shapes how technologists and investors justify continued scaling, even as regulatory pressure mounts elsewhere.

SCENE: Recognizing Social Norms and Sanctioning in Group Chats

Researchers have built SCENE, a benchmark that tests whether large language models can recognize and respect implicit social norms in group chat settings, then adapt behavior when sanctioned by peers. The work evaluates six frontier and open-weight models on their ability to both detect norm violations and learn from social feedback. This addresses a critical gap in agent deployment: most LLM safety work focuses on explicit rules, but real-world collaboration requires implicit norm recognition. The findings will shape how teams think about multi-agent systems operating in social contexts where human groups naturally enforce behavioral boundaries.

GazeVLM: Active Vision via Internal Attention Control for Multimodal Reasoning

GazeVLM introduces a fundamental shift in how vision-language models allocate computational attention by embedding metacognitive control directly into the reasoning pipeline. Rather than passively processing entire visual scenes as static token sequences, the architecture enables models to autonomously generate gaze tokens that dynamically focus on task-relevant regions while maintaining global context awareness. This mirrors human active vision and addresses a core inefficiency in current VLMs: the dilution of spatial reasoning and proliferation of hallucinations caused by indiscriminate token accumulation. The work signals growing recognition that scaling context alone cannot solve reasoning quality, positioning selective attention mechanisms as a critical frontier for multimodal model design.

OrScale: Orthogonalised Optimization with Layer-Wise Trust-Ratio Scaling

OrScale addresses a fundamental constraint in neural network optimization by extending Muon, an orthogonalization-based training algorithm, with layer-wise adaptive scaling. The core innovation replaces global learning-rate control with per-layer trust ratios calibrated to the actual parameter updates each layer receives, solving three failure modes that plague simpler Muon-LAMB hybrids. For language model training specifically, OrScale-LM combines shape-aware scaling with one-time calibration, potentially reducing hyperparameter tuning burden and improving convergence stability. This matters to practitioners because optimizer efficiency directly impacts training cost and model quality, making incremental gains in scaling rules economically significant at scale.

A Comparative Analysis of Classical Machine Learning and Deep Learning Approaches for Sentiment Classification on IMDb Movie Reviews

A comparative benchmark on IMDb sentiment classification reveals that classical machine learning methods, particularly SVM with TF-IDF features, still outperform contemporary deep learning architectures on this canonical task. While BiLSTM with attention mechanisms showed incremental gains over vanilla BiLSTM (70.6% vs lower), the classical pipeline achieved 85.3% accuracy, challenging the assumption that neural approaches universally dominate NLP benchmarks. The finding underscores a persistent gap between deep learning's theoretical appeal and practical performance on well-defined classification problems, relevant to practitioners evaluating model selection tradeoffs.

Beyond Confidence: Rethinking Self-Assessments for Performance Prediction in LLMs

Researchers challenge the assumption that confidence scores reliably predict LLM correctness, proposing instead a multidimensional framework grounded in cognitive psychology. By measuring seven distinct appraisal dimensions across 12 models and 38 tasks, the work identifies competence-related factors as stronger failure predictors than raw confidence. This shifts how practitioners should evaluate model reliability in high-stakes deployments, moving beyond single-metric self-assessment toward richer behavioral signals that better capture when systems are likely to fail.

PolySQL: Scaling Text-to-SQL Evaluation Across SQL Dialects via Automated Backend Isomorphism

Text-to-SQL models are routinely benchmarked on SQLite alone, masking their fragility across production database engines. PolySQL addresses this blind spot by enabling cross-dialect evaluation without manual query translation, using normalized execution results instead. The method achieves complete query coverage where existing transpilation tools fail on complex SQL. This matters because it exposes a systematic evaluation gap in LLM-to-database research: SQLite performance is a poor proxy for real-world deployment readiness. Insiders building or assessing SQL generation systems now have a scalable way to measure true multi-engine robustness.

The work addresses a persistent gap in non-English NLP evaluation, where resource-constrained settings and imbalanced data remain common obstacles. While methodologically straightforward, the study contributes practical validation that hybrid feature engineering remains competitive with neural approaches on small, low-resource corpora, a finding relevant to practitioners deploying sentiment systems in underserved languages.

Chain-based Distillation for Effective Initialization of Variable-Sized Small Language Models

Researchers propose Chain-based Distillation, a method that addresses a critical bottleneck in deploying language models at scale: how to efficiently create smaller variants without repeatedly querying expensive teachers. By constructing a staged distillation pipeline with intermediate anchor models, the approach enables a single LLM to seed multiple target sizes across different architectures. This matters because it directly reduces the computational and financial barriers to edge deployment, making model compression practical for resource-constrained environments where conventional distillation becomes prohibitively expensive.

CktFormalizer: Autoformalization of Natural Language into Circuit Representations

LLM-generated hardware descriptions routinely fail synthesis and routing despite passing syntax checks, a silent failure mode that wastes engineering cycles. CktFormalizer addresses this by embedding hardware generation in Lean 4's dependently-typed system, converting width mismatches, combinational loops, and incomplete logic into compile-time errors that force correctness before synthesis. The framework preserves 100% of valid designs where baseline LLM approaches lose 20% downstream, shifting hardware verification left and reducing the gap between natural-language intent and silicon-ready code. This represents a broader trend of using formal methods and type systems to harden LLM outputs in safety-critical domains.

Using uncertainty profile features like slope and linearity, the approach achieves up to 0.807 AUROC across five models on math and QA benchmarks, substantially outperforming prior work. This work matters because it opens a path toward real-time verification of LM reasoning quality without waiting for final outputs, potentially enabling early stopping, confidence-based routing, or adaptive compute allocation in production systems where reasoning traces are already expensive.

Researchers have identified a fundamental limitation in affine recurrent architectures, a class spanning State-Space Models and Linear Attention mechanisms. The work proves these models cannot correct accumulated errors along dimensions that distinguish symbolic states, meaning practical implementations achieve only finite-horizon state tracking rather than robust long-term reasoning. This finding challenges assumptions about why recurrent systems work in practice and suggests the field has conflated architectural expressiveness with error resilience, a distinction that may reshape how engineers design sequence models for tasks requiring sustained state coherence.
