Earlier quoted context omitted.
Indeed, this article, while interesting, seems to fall into the common trap of overly anthropomorphizing AI. It's a mistake to treat large language models as if they are humans with opinions. While I think many of us want to believe that these models possess some kind of innate intelligence, they are ultimately just algorithms.
I'm aware of this problem but find I lack the vocabulary to make myself concisely understood without anthropomorphizing. Do you have anything I can refer to for a better way to discuss these things?
The basic stylistic rules for avoiding anthropomorphizing are to avoid terms that ascribe intent and to frame your argument in terms of directly observable features.
In this case, I would drop "opinions" and provide explicit definitions for "smarter" and "better-trained". You seem to mean models that are more closely fitted due to more parameters and longer training, so I'll go with that.
Thus, I would rephrase the title as "How do AIs' responses on political topics change as their models become more closely fitted?"
