Thanks all for the suggestions, these were super helpful. I’ve created a new topic to specifically ask about adjoints for non-numeric types: [Adjoint sensitivities for non-numeric types in ModelingToolkit.jl](https://discourse.julialang.org/t/adjoint-sensitivities-for-non-numeric-types-in-modelingtoolkit-jl/132082).
