support using a custom base_url for LLM APIs/ellmer providers

[balling-dev]

Hi,

Thanks a lot for pal (and gander). Would it be possible to add support (e.g. via options) to use a custom base_url for the LLM APIs (the ellmer providers) that support it?

My use case is using pal in an enterprise setting where I need to use a custom base_url for the LLM APIs. This works great today with ellmer (where I can pass base_url as an argument), but I cannot figure out a way to make pal use a custom base_url.

Thanks for your time and effort!

Best,

./ Kristoffer

@balling-dev, thanks for the issue!

This is indeed possible. As the options are currently set up, you would supply .pal_args = list(base_url = ...) and that argument will be passed to the function defined in .pal_fn. That said, those two options are about to be reformatted to just be one option that takes a plain ellmer Chat, so the inclusion of your base_url may be a bit clearer at that point.

Keep an eye on #81 for more!

@simonpcouch Ah yes, of course 😄 . Passing the base_url in .pal_args works great. Thank you so much. I will follow the config changes in #81.

Thanks!
