  It probably depends on the specific application, but I would imagine the models/data that various devices in the field are using are probably updated as part of some periodic maintenance schedule. They don't change significantly enough or quickly enough to demand online updates that frequently, but I suppose every device manufacturer/maintainer has their own way of doing it for whatever reasons they might have.

  In my own work, I've downloaded the dataset from NOAA and their tools to parse and work with this data to generate my own global 1-degree by 1-degree by 1-year "grid" for magnetic declination [0], along with some code [1] to read this data and be able to give you an estimated value for magnetic declination for any position on the globe for any time instant between 2020 and 2025. Before 2025, I will probably need to download the new data, run the tools again, and update my own dataset (to include values for 2025-2030 or whatever the case may be), but this will definitely be a manual process.
