Paper of the Day
World Model Implanting for Test-time Adaptation of Embodied Agents (2025-09-04)
Authors: Minjong Yoo, Jinwoo Jang, Sihyung Yoon, Honguk Woo
Institution: Accepted at the Forty-second International Conference on Machine Learning, 2025
This paper introduces a groundbreaking approach to solving a persistent challenge in embodied AI: enabling agents to adapt to novel environments without extensive retraining. The significance lies in its innovative "world model implanting" framework (WorMI) that combines LLM reasoning capabilities with domain-specific world models through test-time composition.
The researchers demonstrate how their method allows embodied agents to quickly adapt to new domains by implanting and removing specialized world models as needed, maintaining high performance across environments without costly retraining. Their evaluations show superior performance compared to existing adaptation methods, particularly in challenging scenarios with significant domain shifts, establishing a new paradigm for flexible, resource-efficient embodied AI systems.
Notable Research
The Personality Illusion: Revealing Dissociation Between Self-Reports & Behavior in LLMs (2025-09-03)
Authors: Pengrui Han, Rafal Kocielnik, Peiyang Song, et al.
This study reveals a significant dissociation between how LLMs describe their own personality traits and how they actually behave, finding that personality self-reports from models like GPT-4 and Claude have little to no correlation with their behavior in realistic social simulations.
How many patients could we save with LLM priors? (2025-09-04)
Authors: Shota Arai, David Selby, Andrew Vargo, Sebastian Vollmer
The researchers present a novel framework for using LLM-informed prior distributions in hierarchical Bayesian modeling of clinical trials, demonstrating that this approach could significantly reduce the number of patients needed for trials while maintaining statistical power.

Authors: Petr Průcha, Michaela Matoušková, Jan Strnad
This research compares traditional Robotic Process Automation (RPA) with LLM agent-based automation (AACU) across enterprise workflows, providing valuable insights into where LLM agents excel and where traditional automation remains more effective.
Delta Activations: A Representation for Finetuned Large Language Models (2025-09-04)
Authors: Zhiqiu Xu, Amish Sethi, Mayur Naik, Ser-Nam Lim
The paper introduces "Delta Activations," a novel method to represent finetuned models as vector embeddings by measuring shifts in internal activations relative to a base model, enabling better organization and understanding of the growing ecosystem of specialized LLMs.
LOOKING AHEAD
As we enter the final months of 2025, the convergence of multimodal LLMs with embodied AI is accelerating beyond expectations. The recent breakthroughs in low-latency neural architectures suggest that by Q1 2026, we'll see the first generation of truly responsive AI assistants capable of real-time reasoning across visual, auditory, and tactile inputs. Several major labs have hinted at Q4 releases that will significantly reduce the computational requirements for these systems.
Meanwhile, the regulatory landscape continues to evolve, with the EU's AI Act Phase II implementation deadline approaching in early 2026. Companies are racing to establish compliance frameworks, particularly around the new "continuous learning disclosure" requirements for systems deployed in high-risk domains. Those who strategically address these challenges now will likely emerge as leaders in the more regulated—but potentially more trusted—AI ecosystem of 2026.
