Latest 100 papers on large language models: Sep. 14, 2025

The world of Large Language Models (LLMs) is advancing at a breathtaking pace, pushing the boundaries of what AI can achieve. From nuanced human-like reasoning to ultra-efficient deployment on edge devices, recent research showcases a vibrant ecosystem of innovation. This blog post delves into a selection of groundbreaking papers, revealing how researchers are tackling critical challenges and unlocking new capabilities for LLMs across diverse domains.

The Big Ideas & Core Innovations

Of the most profound themes emerging from recent research is the drive towards smarter, more efficient, and more reliable LLMs. We’re seeing innovations that enhance LLM reasoning, mitigate biases, and improve practical deployment. For instance, “The Illusion of Diminishing Returns: Measuring Long Horizon Execution in LLMs” by Akshit Sinha et al. demonstrates that even marginal gains in single-step accuracy can lead to exponential improvements in long-horizon task execution. This highlights the crucial role of scaling and reasoning in complex tasks, especially with “thinking models” like GPT-5. Complementing this, TORSO: Template-Oriented Reasoning Towards General Tasks from Minhyuk Kim et al. at Korea University introduces a template-oriented reasoning method that guides LLMs’ internal reasoning without task-specific prompts, improving generalization and efficiency.critical challenges in LLM deployment, ButterflyQuant: Ultra-low-bit LLM Quantization through Learnable Orthogonal Butterfly Transforms by Bingxin Xu et al. (USC, UCSB, Oumi & UCF) offers a novel solution for extreme quantization, achieving high performance even at 2-bit precision by adapting rotations to layer-specific outlier patterns. This innovation makes powerful LLMs viable for resource-constrained environments. Privacy and security are also paramount, with ENSI: Efficient Non-Interactive Secure Inference for Large Language Models by Hao Huang and Jinlong Chen from Tsinghua University, which introduces a framework for non-interactive secure inference using homomorphic encryption and GPU optimization. Further bolstering privacy, Towards Confidential and Efficient LLM Inference with Dual Privacy Protection introduces the CMIF framework, combining differential privacy with Trusted Execution Environments (TEE) to reduce communication overhead and enhance data protection.and ethical considerations are also at the forefront. PerFairX: Is There a Balance Between Fairness and Personality in Large Language Model Recommendations? by Chandan Kumar Sah from Beihang University, explores the trade-offs between demographic fairness and psychographic personalization, revealing how personality-aware prompts can improve user alignment but exacerbate disparities. In a similar vein, YouthSafe: A Youth-Centric Safety Benchmark and Safeguard Model for Large Language Models from Yaman Yu et al. at the University of Illinois, Urbana–Champaign, introduces a benchmark and a model specifically designed to detect and mitigate youth-specific risks in LLM interactions, significantly outperforming existing systems.
