Just for clarity on this comment and a separate one, Niantic is a Google spin out company and appears to still be majority shareholder: https://en.wikipedia.org/wiki/Niantic,_Inc.#As_an_independen...
Google actually has released weights for some of their models, but judging by the fact that this model is potentially valuable, they likely will not allow Niantic for this
I kept wondering why a Google spinoff was named after a river and community in Connecticut, one of the least Googley locales in the country.
The connection is a ship, built in Connecticut, which brought gold rushers to San Francisco and was run aground and converted to a hotel there: https://en.m.wikipedia.org/wiki/Niantic_(whaling_vessel)
The company was named after the ship.
