Curveball Steering: The Right Direction To Steer Isn't Always Linear

This paper challenges the Linear Representation Hypothesis by demonstrating that LLM activation spaces exhibit significant geometric distortion, leading to the proposal of "Curveball steering," a nonlinear intervention method using polynomial kernel PCA that outperforms traditional linear approaches by better respecting the intrinsic geometry of the model's feature space.

Beyond Scaling: Assessing Strategic Reasoning and Rapid Decision-Making Capability of LLMs in Zero-sum Environments

This paper introduces the Strategic Tactical Agent Reasoning (STAR) benchmark, a multi-agent framework for evaluating LLMs in zero-sum environments, which reveals a critical trade-off where reasoning-intensive models excel in turn-based settings but often underperform in real-time scenarios due to latency, highlighting the need to balance strategic depth with rapid execution.
