LLM Evaluation & Benchmarks

  • ConceptGuard introduces a benchmark for context-⁠sensitive unlearning in LLMs, focusing on dual-⁠use concepts to evaluate removal of harmful behaviors while preserving benign knowledge, addressing gaps in prior disjoint forget/retain set approaches [1].
  • AI4AI-⁠Bench targets recursive self-⁠improvement by testing LLM agents' ability to rewrite training algorithms within a fixed time budget, isolating algorithmic design from data collection or hyperparameter tuning [2].
  • Phantom Gains audits self-⁠improvement claims by differencing noisy estimates against a frozen control, exposing measurement artifacts (e.g., inference batching, expansion statistics) and proposing exact per-⁠problem tests against pooled baselines [3].
  • FormalTCS benchmarks end-⁠to-⁠end frontier formal TCS research with 175 instances from 2025–2026 papers, revealing autoformalization as the sharpest bottleneck (11.5 vs. 28.6 Pass@8 for proof generation) [4].
  • OenoBench offers a wine-⁠domain knowledge benchmark with 3,266 MCQs, source-⁠anchored facts, and LLM-⁠audited pipelines, showing accuracy spans of 53%–84% across 16 frontier models [5].
  • SOP-⁠Bench evaluates AI agents on real-⁠world standard operating procedures (SOPs) from industries like healthcare, logistics, and finance, highlighting challenges in interpreting implicit instructions, leveraging domain knowledge, and making judgment calls [6].

LLM Capabilities & Methods

  • MidTool proposes a mid-⁠training data synthesis pipeline for agentic tool use, combining web/PDF/code data with API/MCP supervision to teach tool affordances, argument grounding, and workflow composition, improving Qwen3 models after post-⁠training [7].
  • IAR (Inject, Align, Recover) is a three-⁠stage post-⁠training framework for retrieval-⁠free document knowledge internalization, separating injection, QA alignment, and general ability recovery to improve domain-⁠specific and general performance [8].
  • Daedalus-⁠150M introduces a convolution-⁠attention hybrid architecture optimized for CPU inference, using short convolutions to limit memory growth and outperforming larger baselines on a 5-⁠task benchmark [9].
  • RuleMaze benchmarks rule-⁠compliant visual spatial planning for MLLMs, using Language-⁠Logic-⁠Function Hybridization to auto-⁠generate rules and validators, and proposing disentangled rule representations for better generalization [10].

Agentic Systems & Reasoning

  • Pandora’s Router/Bidder formalizes model routing as a Pandora’s Box problem, deriving closed-⁠form value-⁠of-⁠information policies to decide whether refining value estimates is worth the cost for heterogeneous AI systems [11].
  • Learning When to Think trains a 1.5B model to adaptively choose reasoning modes (NoThink/Short/Long) via GRPO with shaped rewards and token caps, showing modes emerge without collapse and sort problems by difficulty [12].
  • Break It Down, Pass It On studies cross-⁠task skill transfer in LLM agents, finding subtask-⁠level skills outperform task-⁠level ones, and text skills transfer better than code, with specificity/abstractness as key properties [13].
  • Task-⁠CoEvolve optimizes LLM agent harnesses via adaptive validation task selection, focusing evaluation on tasks where candidate harnesses disagree to reduce costs while maintaining discriminative power [14].

Safety, Fairness & Governance

  • InsufficiencyBench evaluates LLM legal advice on underspecified queries, formalizing missing-⁠element categories (switch/gating/fatal prerequisite) and showing frontier models achieve ≤0.46 F2 on identifying missing information [15].
  • ContractScrub introduces the first benchmark for legal contract scrubbing, testing LLMs on error detection (e.g., defined terms, references, inconsistencies) in handcrafted contracts [16].
  • Auditing Cross-⁠Lingual Fairness in Watermarking proposes a framework with calibrated thresholds, threshold-⁠independent metrics, and typological decomposition, revealing scheme-⁠specific failures across 11 languages and 4 scripts [17].
  • MemTrapBench evaluates cognitive traps in LLM memory use, showing that retrieved memories can distort reasoning (Reasoning Fixation, Belief Distortion), with all tested memory strategies underperforming no-⁠memory baselines by >10% [18].

Domain-⁠Specific Applications

  • G-⁠CARL addresses patient-⁠oriented medical report interpretation with a grounded, checklist-⁠aligned RL framework, combining retrieval for claim verification with context-⁠aware alignment to balance factuality and communication [19].
  • BERT-⁠LER integrates laboratory test results as discrete tokens with percentile binning in a BERT-⁠style EHR model, paired with Integrated Gradients for explainability, showing strong performance on EHRShot and asthma severity tasks [20].
  • QUASAR presents a quantum-⁠classical hybrid (CNN + VQC) for X-⁠band SAR satellite physical-⁠layer authentication, achieving data efficiency (10% training data) while matching classical baselines [21].

Theoretical & Algorithmic Advances

  • Relation-⁠based token mixing introduces Full/Flash/Linear Relation primitives as alternatives to attention, showing lower validation NLL than MHA at matched scales and strong throughput (76.4–84.9% of FlashAttention) [22].
  • Discrete Diffusion Inference-⁠Time Control proposes nested sequential Monte Carlo (NSMC/FA-⁠NSMC) for steering text generation in discrete diffusion LMs, outperforming best-⁠of-⁠n and bootstrap SMC on toxicity/fluency tasks [23].
