My approach to this problem is to just...not try them all.

As long as the model you're using solves the problems you have to your satisfaction, there is no need to try any other models, except for financial reasons maybe.

So I start with a relatively cheap model (GLM 5.3 flash for me) and as long as it accomplishes the task (it did so far) I don't have to change. And even if it can't do something, the first thing I change is see if I can give it more tools or better context (useful even if I switch models later) or trying a different approach to the problem.

If google/gemma-4-31b works, you don't need to overthink it.
