We provide an abstract characterization for the Cuntz semigroup of unital commutative AI-algebras, as well as a characterization for abstract Cuntz semigroups of the form Lsc(𝑋, N) for some 𝑇 1 -space 𝑋. In our investigations, we also uncover new properties that the Cuntz semigroup of all AI-algebras satisfies.
