Calibration Drift Under Reasoning: How Chain-of-Thought Budgets Induce Overconfidence in Large Language Models

Researchers discover that Chain-of-Thought reasoning in large language models can paradoxically increase overconfidence when reasoning budgets exceed task-specific thresholds, a phenomenon called Calibration Drift Under Reasoning (CDUR). The study shows that while extended reasoning initially improves accuracy, it eventually produces internally consistent but incorrect explanations that mislead models into false confidence, with implications for safe LLM deployment.

The Dunning-Kruger Effect in Large Language Models: An Empirical Study of Confidence Calibration

A new study reveals that large language models exhibit patterns similar to the Dunning-Kruger effect, where poorly performing AI models show severe overconfidence in their abilities. The research tested four major models across 24,000 trials, finding that Kimi K2 displayed the worst calibration with 72.6% overconfidence despite only 23.3% accuracy, while Claude Haiku 4.5 achieved the best performance with proper confidence calibration.

Towards Understanding The Calibration Benefits of Sharpness-Aware Minimization

Researchers demonstrate that Sharpness-Aware Minimization (SAM), a recently proposed neural network training method, significantly improves model calibration by reducing overconfidence in predictions. The study includes a new variant called CSAM that further enhances calibration performance across multiple datasets, with important implications for safety-critical AI applications.

GIScholarBench: Benchmarking LLM Overconfidence in GIS Research

Researchers introduced GIScholarBench, a benchmark testing whether large language models exhibit overconfidence when performing academic research tasks. Evaluating Claude, Gemini, and ChatGPT on 10,865 GIS papers, the study found all models generate confident outputs even when knowledge is incomplete, particularly in citation generation and research ideation tasks.
