It’s fairly hard to come up with a nice abstract interface on this because different methods can work very differently or use very different information. But the closest to a common interface is DyadModelOptimizer, but in order for that to work it needs the ModelingToolkit.jl symbolic knowledge of the model, whereas SciMLSensitivity says “go ham on your own”, DiffEqParamEstim wants general diffeq models, etc.
