Isn't general relativity just a way to interpret reality instead of what reality is?

I mean, just a very accurate model of reality. But anything can be anything in any model, which is cool as long as the model has some kind of utility.

(?)

Or, are we accepting that objectively gravity is definetely not a force?

General Relativity describes gravity as the geometric result of space and time being the medium through which matter travels. Quantum Field Theory hasn't been able to describe gravity at the subatomic level though. So in conclusion I'd say we have no idea if the description of gravity we have using General Relativity is 'real' or just a really good prediction tool.

I'm also not really sure how we would differentiate between calling something reality and a perfectly predictive model.

I think you could say that most astronomers consider gravity geometry, not a force, but some physicists might not agree.
