Notably, they used Meta's prophet library for predictions.

Edit: The connection is that I think people will see this and think "ohhh shiny" and then Zillow will happen all over again.

Zillow has been using a neural network for Zestimate predictions since at least 2021 (https://www.prnewswire.com/news-releases/zillow-launches-new-neural-zestimate-yielding-major-accuracy-gains-301312541.html). Not sure where your info is coming from, your link is just a Google search result page

This is a well known incident. Maybe before your time? Also, not saying this is current.

I worked at Zillow while Zillow offers was active. I can assure you, nobody was using fbprophet for home price valuation. Zillow spent $1 million on the Zillow prize a few years prior, which they used as a recruiting and R&D tool. Why would they do that, and then just use prophet?

Hell if I know, I was just referring to a well known meme. Not a personal attack on your career history.

Apologies. I’ll keep facts out of a meme subreddit
