The paper introduces the concept of LLM Parkinsonism, describing how large language models can persist in low‑value actions after completing their objectives. It proposes a Global Executive Control (GEC) architecture that separates action generation from project‑level oversight, achieving comparable success to candidate‑set control while significantly reducing token usage and complexity. Experimental results on a 24,000‑episode benchmark show GEC cuts mean token use by 36.4% and limits token consumption at the 40,000‑token ceiling by 18.7%, eliminating pre‑completion drift.

The paper applies the AICON reactive gradient‑descent framework, originally designed for robotic manipulation, to the Tower of London cognitive test. AICON, without any lookahead planning or human cognition knowledge, reproduces the fine‑grained difficulty ordering of 24 problems better than structural task parameters and generalizes to held‑out problems. It outperforms a planning baseline for groups with reduced planning capacity (e.g., Parkinson’s patients) while the baseline better captures healthy controls, indicating that reduced planning capacity shifts human behavior toward a reactive mode similar to AICON’s failure patterns.
The paper introduces the Agent-Editing World Model (AEWM), a new approach that models how reasoning and actions influence future task progress instead of simulating tool responses. AEWM includes an Action Judge that classifies decisions as Critical, Exploratory, or Noisy, and a State Revision mechanism that edits noisy reasoning–action continuations from the same observed history. The integrated system, EditAct, directly updates the underlying state during real execution, leading to significant performance gains across multiple benchmarks and agent backbones.
GRASP is a multi-stage planning framework that separates planning into specialized modules: GenPlan for global macro-guidelines, RevPlan for exploring localized strategies, and VerPlan for multi-criteria evaluation. This strategy-aware approach yields state‑of‑the‑art accuracy on diverse datasets, outperforming direct LLM planners by up to 30.8% on ZebraLogic and reducing multi‑task degradation. GRASP’s context isolation and macro‑regularization also give it a 14.5% edge over frontier reasoning models like GPT‑5‑mini.
GRASP is a multi-stage planning framework that improves the reliability of large language models on complex tasks. It separates planning into three specialized modules—GenPlan for global macro-guidelines, RevPlan for exploring localized strategies, and VerPlan for multi-criteria evaluation—allowing context isolation and strict macro-regularization. Experiments show GRASP outperforms direct LLM planners by significant margins on datasets such as Natural Plan Calendar Scheduling, ZebraLogic, and SciBench Math, and it mitigates performance collapse in multi-task and dual-task settings.

LM‑X is a generalist vision‑language‑action policy that augments action prediction with three online, explicitly supervised signals: return‑to‑go (RTG) for task progress, event‑to‑go (ETG) for the next semantic transition, and heteroscedastic action flow for local reliability. By conditioning action generation on these signals, LM‑X embeds explainability directly into control rather than as a post‑hoc explanation. After a 20‑day pretraining run on 64 GPUs, LM‑X outperforms an action‑only backbone by 16.0 points and a single‑head variant by 10.8 points, and achieves 74.1 % success on 50 RoboTwin2.0 tasks and 68.6 % on seven real‑robot tasks, surpassing the GR00T N1.7 baseline.
