It’s machine learning, which people routinely called AI not so long ago.
I never heard people calling machine learning "AI" until large language models made it trivial to market it as such. Like, I remember back when Netflix, for instance, was going around advertising how machine learning (not AI) powers their recommendations.
ML was always marketed separately as AI/ML, with AI being things like CNNs/RNNs/BERTs and such. Always felt like a distinction without a difference.
