Overthinking Large Language Models: New DoS Threat to Reasoning Models Unveiled

The paper introduces a black‑box hierarchical genetic algorithm that automatically perturbs the logical structure of reasoning questions to induce excessive chain‑of‑thought in large language models, dramatically inflating output tokens (up to 26.1× on MATH) and creating a DoS‑style resource‑exhaustion attack, with extensive experiments across multiple models demonstrating the vulnerability and its transferability.

DECS Cuts Overthinking in Models: Halve Inference Tokens and Raise Accuracy

DECS, a novel training framework introduced by researchers from Fudan, Shanghai Jiao Tong, and the Shanghai AI Lab, theoretically exposes the flaws of length‑penalty rewards and, through token‑level reward decoupling and dynamic batch scheduling, reduces inference token counts by over 50% while improving accuracy across multiple benchmarks.

Why LLMs Overthink and How Developers Can Control Inference Depth

Developers notice that large language models often enter an "overthinking" mode that slows down simple coding tasks, prompting calls for adjustable inference depth controls so models can switch between quick checks and deep analysis based on task risk level.
