What is better method for using models from palette like 'Math/Add'? There are two ways:
1) Taking model from palette everytime we need it.
2) Taking one model when we need it. Next time we want to use such model, we take it from repository - so it's reused.
'Math/Add' will always take 2 numbers and return one number - so there won't be type compatibility problems in different actions.
If we have let's say 1000 uses of such model is there any performance difference?
