I'm having trouble understanding how to run a model graded eval

[mayalinetsky-kryon]

Hey,
I've read the documentations about how to run an eval, but I could not figure out how to run the ones under evals/registry/modelgraded (and specifically I want closedqa.yaml).

I'm interested in running a modelgraded eval on gpt-3.5-turbo with a custom system message.

How do I do that?
Where does the system message come in?

Hey, I've recently got 2 pull requests approved on this, check out gpt4facts and A is B, B is A pull requests. Something that also helps is to checkout merged pull requests that used modelgraded. There is also some documentation on them and I suggest reading the files on modelgraded to see what it is doing and how it works.

I also have hard time understanding how to use model graded eval, could someone please give a concrete example (like a command)?
