If someone starts running this model couldn’t you just run the model yourself to predict the order?

I’m sure that there is market microstructure stuff/front running practicalities that would make this harder than it sounds but still you wouldn’t completely be in the dark.

But how would doing that constitute front running?

Front running has a specific definition in terms of market regulation (see my other comment) and what you describe is not front-running.
