Indentify parameters in an ODEProblem

Alternatively, you can do something like

# `copy` also works for `MTKParameters`, but `deepcopy` works for everything
newp = deepcopy(parameter_values(prob))
setp(sys, [syms...])(newp) # ideally cache the result of `setp(...)`
remake(prob, p = newp)

If the types of the variables don’t change.
