Researchers extended a benchmark study on LLM agent cooperation across four frontier models (Claude Sonnet 4.6, Gemini 2.5 Flash, Gemini 3.1 Pro, GPT-5.4 Mini) using game theory simulations. While cooperative bias persists across providers, substantial divergence exists—Gemini models lean aggressive while GPT-5.4 Mini favors cooperation—suggesting provider identity, not model scale, drives equilibrium behavior.
Researchers introduce a strategy-level evaluation framework for large language models on mathematical reasoning tasks, revealing a significant gap between high answer accuracy and actual reasoning flexibility. While frontier models achieve 95-100% accuracy on single-solution prompts, they recover substantially fewer problem-solving strategies than human references when asked to generate multiple approaches, with only 39-71% coverage depending on the model and iteration count.
Researchers introduce the Metacognitive Probe, a diagnostic tool measuring five dimensions of LLM confidence behavior including calibration, epistemic vigilance, and reasoning validation. Testing on eight frontier models and 69 humans reveals significant within-model disparities—exemplified by Gemini 2.5 Flash scoring 88 on confidence calibration but only 41 on difficulty prediction—suggesting composite benchmarks mask pockets of overconfidence.
Researchers introduce WorldTest, a new evaluation protocol for assessing whether AI agents learn general-purpose world models capable of answering diverse environment-level queries.
