I think the `objective_bound` is valid. And when it is solved to optimal, the 2 values coincides.  
I find a new problem, please see my new topic.[Gurobi12 reports obj\_value \< obj\_bound in a Min-Program?](https://discourse.julialang.org/t/gurobi12-reports-obj-value-obj-bound-in-a-min-program/126849)
