AI makes AR more useful, and overcomes some core limitations of AR, which include a constrained field of view within which it is difficult to include more than one panel of UI buttons and interactions.
The inverse is also true: AR helps AI more concrete. In the context of data visualization, LLMs can identify how to process massive amounts of data quickly, identify patterns, and present insights, but the results are usually limited to text. On the other hand, AR can provide an interactive, immersive platform to visualize these insights and/or anchor the insights within the larger context of the scope of the data.
