5/ The passage defines and clarifies what the report means by AGI, ASI, and a theoretical upper bound called UAI, emphasizing that intelligence is treated as a continuum rather than a sharply defined threshold.
AGI (Artificial General Intelligence): Defined as roughly median human-level intelligence across most cognitive tasks. Even this level of AI would already be superhuman in many narrow domains, but still not fully general. It corresponds to a “competent human-equivalent” system.
ASI (Artificial Superintelligence): A system that is broadly and significantly more capable than humans across nearly all domains of interest. Unlike narrow superhuman systems (e.g., AlphaGo or AlphaFold), ASI would outperform not just individuals but large groups of human experts across almost all tasks. It may also consist of many interacting AI instances working in parallel.
UAI (Universal AI): A theoretical upper limit of intelligence defined in formal terms (via the Legg-Hutter framework and AIXI). It represents the maximally intelligent possible agent in principle, but is not computable in practice. ASI is viewed as an approximation that can progressively approach this limit.
