Google's Recommendations AI now in public beta

>Recommendations AI is based on technology that Google says it uses to deliver recommendations on its own products, including YouTube and Google Search. The cloud company says retailers can use the tool to replace or complement existing recommendation models.

Hopefully some people write their thoughts on this after exploring the API. I have a rather general interest in algorithimic-powered recommendations when compared to human curated, so it should be interesting to see how this functions. This is assuming that, despite Google using it across a number of service types, Recommendations AI is not solely aimed at product purchases.
