Are you not better off with cheaper models like GLM 5.3 or GLM 5.3 Flash? As a lot of that work is repetitive and only needs a stronger model at later stages of cleanup, no?
Of course I don't run everything on Sol. But weaker models can only do very basic things. I have a round robin style workflow where each unit first gets 10 cycles of each luna medium -> high -> terra medium -> terra high -> Sol Medium -> Sol high -> Sol Ultra. And you can clearly see that luna and terra only get a small amount of real progress.
