The Takeaway
While AI once showed a 'general factor' (g) where all skills improved together, recent reasoning models are breaking this trend. Instead of one all-knowing mind, we are moving toward a pack of 'specialized foxes' that are elite in specific tasks but lack a unified core.
From the abstract
In the psychological literature the term `general intelligence' describes correlations between abilities and not simply the number of abilities. This paper connects Spearman's $g$-factor from psychometrics, measuring a positive manifold, to the implicit ``$G$-factor'' in claims about artificial general intelligence (AGI) performance on temporally structured benchmarks. By treating LLM benchmark batteries as cognitive test batteries and model releases as subjects, principal component analysis is
