Revisiting Generalization Across Difficulty Levels: It's Not So Easy

The article's title suggests a critical examination of how well AI models, likely LLMs, generalize their knowledge across varying levels of task difficulty. The phrase "It's Not So Easy" implies that the research likely reveals limitations or challenges in this area, potentially highlighting a gap between theoretical capabilities and practical performance. The source, ArXiv, indicates this is a research paper, suggesting a rigorous, data-driven analysis.
