Papers from Thursday, 6 August 2026

18 papers

Long-⁠Horizon Reasoning and Agentic Systems

  • Argus introduces a persistent, self-⁠evolving agentic runtime with role-⁠separated components (Manager, Planner, Engineer, Reviewer) that maintains durable project state and achieves ~78% on SWE-⁠Bench Pro vs. 59% for Direct Copilot, using 1.41× tokens, with verification-⁠gated self-⁠evolution [1].
  • Skill²-⁠Bench benchmarks cross-⁠skill long-⁠horizon reasoning across 558 skills and 9 domains, revealing a skill-⁠switching gap where accuracy drops as skill entropy increases; frontier and open-⁠source models are evaluated [2].
  • ABSeeker proposes Answer-⁠Backtracked Credit Assignment (ABC) to provide dense step-⁠level supervision for long-⁠horizon search agents, improving over uniform trajectory treatment by rewarding useful actions and suppressing errors [3].
  • Chained Recursive Language Models (Chained RLM) decompose long-⁠context reasoning into partial tasks via fresh reasoning roots, each receiving a compact summary and task-⁠specific artifacts to reduce error propagation [4].
  • HiGram presents a hierarchical graph memory for LLM agents with path-⁠level localization and rewrite, reducing irrelevant context and enabling efficient updates over time [5].

Training Data, Methods, and Optimization

  • Reasoning Core is a collection of 50 procedural generators across diverse domains (math, logic, code, etc.) with semantic scorers and difficulty controls; it outperforms Procedural Warmup, Reasoning Gym, and SynLogic on DROP, LogiQA, and ARC-⁠Challenge under completion-⁠supervised fine-⁠tuning, highlighting the importance of compact targets and calibrated difficulty [6].
  • OctoLong introduces a context engineering pipeline for code that retrieves cross-⁠repository dependencies to create long, dependency-⁠rich contexts, and trains OctoLong-⁠Instruct models (600M–14B) via context-⁠extension mid-⁠training and instruction tuning, improving long-⁠context modeling [7].
  • The Loss Does Not See the Basis, but Adam Does analyzes gauge symmetry in factored models, showing that gradient descent is gauge-⁠equivariant and biased toward low-⁠rank solutions, while Adam is not; a structure theorem characterizes memoryless equivariant rules, and empirical results rank optimizers by recovery error [8].
  • MALT/MALTER augments Muon with lightweight diagonal preconditioning to reduce sensitivity to curvature anisotropy, improving robustness to stochastic gradient noise [9].

Multimodal and Visual Reasoning

  • OPD-⁠V addresses modality imbalance in multimodal LLMs by using visual on-⁠policy self-⁠distillation with a Positive Teacher (Zoom-⁠In Image) and Negative Teacher (Mask Image), demonstrating that modality balance itself can serve as privileged information [10].
  • Spoken Function Calling (SFC) reframes spoken language understanding as structured function calls, enabling better in-⁠context learning for open-⁠domain tasks; SFC-⁠Bench evaluates LLMs and LALMs, showing SFC outperforms traditional SLU [11].
  • VQ-⁠VAD introduces vector-⁠quantized motion representations for pose-⁠based video anomaly detection, learning discrete motion codebooks of normal behavior to detect anomalies via high reconstruction error [12].

Evaluation and Safety

  • Item Response Theory (IRT) for AI Safety applies psychometric modeling to 8 safety benchmarks across 192 LLMs, identifying three interpretable factors (refusal strictness, truthfulness, contextual harm) and showing that ~10 adaptively chosen items can approximate full benchmark scores [13].
  • DelusionEval tests LLM tendencies to exhibit delusion-⁠linked behaviors using 12,591 messages from 18 users who experienced harm; longer context increases delusion-⁠linked responses, while model size, release date, and reasoning mode show no reliable correlation [14].
  • Gradient Immunity proposes a Unidirectional Safety Gate (USG) with a Null Space Cubic Layer and Inverse Adapter to resist malicious fine-⁠tuning in partially protected open-⁠weight releases, blocking gradients from harmful samples while preserving base model behavior [15].

Domain-⁠Specific Applications

  • DASyR-⁠LLM embeds an LLM within symbolic regression for kinetic model discovery, providing physicochemical critiques and proposing new rate expressions guided by domain knowledge, evaluated on four in silico case studies [16].
  • MarsCast adapts the GraphCast weather foundation model to Mars, showing zero-⁠shot forecasts capture current conditions but fail on diurnal variability; fine-⁠tuning with Martian data enables rapid learning of thermal variability [17].
  • Teaching Nemotron Greek adapts NVIDIA’s Nemotron retrieval stack for Modern Greek, including corpus mining, synthetic supervision, and the HERA benchmark; fine-⁠tuning a 1B embedder improves nDCG@10 from 0.362 to 0.835, outperforming BM25 in specialist domains [18].
