The differences between the NLPModels.jl counters and CUTEst’s native counters come from how each system tracks function evaluations internally.
- NLPModels.jl increments its counters every time a Julia wrapper function is called, so it reflects exactly what the user code requests.
- CUTEst, on the other hand, sometimes counts extra internal calls (for things like Hessian, Jacobian, or constraint evaluations) or may skip counting certain evaluations, depending on whether the problem is constrained or unconstrained and how its Fortran backend is implemented.
- For example, in constrained problems, CUTEst might not increment the objective counter, or it might count an extra call for Jacobian or constraint evaluations due to its internal logic. These differences are expected and are documented in the test file.

@arnavk23 A counter for jtprod is missing.
Otherwise LGTM 👍

Sorry for the long delay @arnavk23, I was working on many projects recently.
