In this case there is enough implicit context to infer the correct meaning, but that is not always the case. However I still think it is phrased poorly as it does initially seem to imply your personal assistant has become an AI agent, but then I have to use additional knowledge I posses (that people can not become AI agents) to correct the interpretation. I think a better phrasing would be “I now use an AI agent as a personal assistant”. No confusion there. Your phrase can be understood, just like the article title, but it’s not well-written English IMO.
