> the training cutoff date isn't some absolute date from which they never allowed any new data to be trained on.

It's not a question of whether they are "allowed" to train on new data; the question is whether they have trained it on data containing information about current events. If you know they've implemented a Continuous Integration (CI) system for this, you should link to a source. However, I don't think this is true, as there would be no reason for a cutoff date otherwise.

> Instead there are bits and pieces of newer information captured in the updated models, but it's not a meaningful enough amount to ever rely on.

This seems more like an opinion of the technology's limitations in general, rather than an assessment of the likelihood that new information will be incorporated into its weights and biases.
