Question about Instant Pot Ceramic inner pot

The ceramic inner pot is specially designed for Instant Pot multicookers and does not fit multicookers from other brands such as the Ninja 14-in-1. Compatibility is limited to certain Instant Pot models.

I'm not entirely sure if it will fit your Ninja as the information does not confirm compatibility with other brands. It is best to check the dimensions and shape of the pot again directly with the manufacturer.
