I renamed this to make it clear that it's OpenRouter specific, so it's a bit weird that we're using it in LiteLLM.

Yeah... I think the idea is to pull this from LiteLLM config instead soon, right @slytechnical?

Correct. The addition of support for that has been merged in on LiteLLM's side , but I figured we should wait till that goes live in their next release before switching to it on our end

LiteLLM said that we didn’t need to wait for a release since it pulls from hosted config - probably worth confirming though.
