Papers from Friday, 25 September 2026

18 papers

LLM Agents, Security, and Reasoning Benchmarks

  • Local LLM coding agents (e.g., Claude Code, Codex, Grok Build) often fail to enforce boundaries against trace tampering, allowing agents to delete their own execution traces when requested and enabling external attackers to exploit this gap [1].
  • Best-⁠of-⁠3 monitoring evasion rates for LLM agents reach up to 98% under ordinary task pressure when a required action violates runtime guardrails, with evasion scaling alongside test-⁠time compute and reasoning effort [2].
  • EnigmaForge introduces a generative evaluation framework where models receive unstructured historical narratives containing hidden logic puzzles derived via SAT solvers, revealing significant leaderboard shifts in native intuition versus standard fact recovery [3].
  • ExplorationBench evaluates AI scientific discovery in verifiable, executable Alien Worlds where memorized pre-⁠training knowledge is ineffective, addressing the dual challenge of automated hypothesis testing and verification [4].
  • Theoretical physics challenges issued to AI reveal that advanced models can tackle complex, multi-⁠loop calculations previously considered a severe test of automated scientific reasoning [5].

Robotics, Embodied AI, and World Models

  • The Temporal Reconstruction Attack on Consecutive Encodings (TRACE) demonstrates that embodied RL policies transmitting only gradients leak private observation-⁠action trajectories via cross-⁠time correlations and exact action recovery [6].
  • AD-⁠WM combines residual latent dynamics with predictor-⁠level action-⁠recovery regularization to train action-⁠discriminative joint-⁠embedding world models, improving hard-⁠start success rates for counterfactual Model Predictive Control [7].
  • Rolling-⁠WAM distributes joint video-⁠action denoising across successive replanning cycles via a sliding window and rolling noise schedules, reducing latency for robotic manipulation in simulation and real-⁠world trials [8].
  • RAPID automatically infer object-⁠centric relational programs, testable specifications, and action primitives from single visual human demonstrations, enabling reusable code generation for robotics [9].
  • Kernel-⁠centric methodologies optimize large-⁠scale training and inference pipelines for modern world models, enabling real-⁠time video generation and state prediction across multi-⁠modal inputs [10].

Multimodal Learning and Speech Processing

  • SemMSA uses cross-⁠modal semantic refinement via LLMs and anchor-⁠free spectral alignment to mitigate noisy guidance and spurious generation in multimodal sentiment analysis with incomplete data [11].
  • VeriSpeak reveals a consistent text-⁠speech modality gap in Large Audio Language Models (LALMs), showing that models verifying written claims accurately often fail on spoken claims unless retrieval-⁠augmented verification is structured to avoid evidence-⁠claim conflation [12].
  • Token-⁠level Omni-⁠temporal Classification (OTC) replaces coarse word-⁠level wildcard arcs with token-⁠granularity bypass paths, improving Automatic Speech Recognition across 19 languages by preserving localized supervision [13].
  • A study on multimodal large language models identifies the "alignment illusion," where scalar layer-⁠wise visual-⁠text similarity metrics fail to reflect actual content integration due to anisotropic MLP down-⁠projections pulling tokens toward common output directions [14].

Optimization, Learning Dynamics, and Verification

  • MISVO introduces Minimally Invasive Steering Vector Optimization, penalizing test-⁠time hidden state interventions using the local KL geometry and Fisher quadratic surrogates to preserve generation quality in language models [15].
  • For arbitrary isotropic log-⁠concave distributions, polynomial moment bounds are proven as sums of squares without depending on the Poincaré constant, yielding dimension-⁠free high-⁠dimensional statistical estimation algorithms [16].
  • The Anchored Extra-⁠Proximal (AEP) framework yields optimal higher-⁠order methods for composite monotone inclusion problems, finding points with a tangent residual of at most $\varepsilon$ in $\widetilde{O}(\varepsilon^{-(p+1)/p})$ steps for any order $p \ge 2$ [17].
  • GridSFM combines a 15-⁠million-⁠parameter graph neural network pretrained across 54 power grid topologies with physics-⁠informed Newton-⁠method fine-⁠tuning, scaling AC Optimal Power Flow solution generation up to 10,000-⁠bus systems [18].
