I'm generally interested in adding more LLM providers, but my time is limited and i personally only use Claude, so the motivation is rather... limited.

I'd first have to refactor slightly to allow for more providers to be implemented without a hassle.

Yeah, open to PRs here or wait till I do it myself.
