I am using cProfile to profile gurobi. Unfortunately, the calls to Model.optimize() do not seem to appear, despite having the largest cumulative time.

Is there any solution besides manually profiling specfic lines with timeit?

  I found this package which provides profiling by line. Contrary to cProfile, it does show Model.optimize() as the most time-consuming line.

  You could try wrapping the call to Model.optimize() in a simple function:

  import gurobipy as gp
  import cProfile
  
  def main():
      m = gp.Model()
  
      # Build model here
  
      optimize(m)
  
  def optimize(model):
      model.optimize()
  
  cProfile.run('main()')
