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.

Reinforced Planning with Latent World Models (RP1) is a novel method that learns to evaluate imagined outcomes via a critic and to improve multi‑step plans through an optimizer trained offline on world‑model roll‑outs. It is the first approach to fully learn plan improvement and can be attached to any pretrained latent world model. In experiments on visual navigation, arm reaching, and robotic manipulation, RP1 outperforms hand‑designed search algorithms, achieving near‑perfect success while using far fewer roll‑outs and running up to 67× faster than the strongest alternative.

Reinforced Planning with Latent World Models introduces RP1, a neural planner that learns to evaluate imagined outcomes via a critic and improve multi‑step plans through an optimizer trained offline on world‑model roll‑outs. Unlike existing planners that are hand‑designed or only inform policies, RP1 fully learns to refine plans and can be attached to any pretrained latent world model. In experiments on visual navigation, arm reaching, and robotic manipulation, RP1 outperforms hand‑designed search algorithms, achieving near‑perfect success while using 1,000× fewer roll‑outs and up to 67× faster inference.
