### The Feature

Hello,

I would like to have a list of available models for an api_base.

### Motivation, pitch

As of today, when you're doing a completion, you have to specify the model : https://docs.litellm.ai/docs/completion/input

But what if you don't know which models are available?

I currently work on [Amphi ETL](https://github.com/amphi-ai/amphi-etl), a python-based no-code ETL. I would like to develop a way to ask a LLM for each row of a dataframe. But as a developer, I don't know what model is available for the user (let's say i don't even know the said user). Therefore, what I have in mind is something like the user give the api_base, I send a request to retrieve the available models and propose the models to the user. This would be fantastic for me.

### What part of LiteLLM is this about?

SDK (litellm Python package)
