Description

By using default config.json with a codestral API key (not the general one), I get an error popup: "message":"Unauthorized" on each completion attempt:

This can be fixed by adding: "apiBase": "https://codestral.mistral.ai/v1" to the tabAutocompleteModel

But according to documentation (https://docs.continue.dev/autocomplete/model-setup), I understand that i should set apiBase only when using the general API.

Here i understand that https://codestral.mistral.ai/v1 is the default value when using codestral:
https://github.com/continuedev/continue/blob/main/core/llm/llms/Mistral.ts#L23

But somehow, this does not seems to be taken into account.

I do not know if the code should be fixed to use it as default apiBase, or if the documentation should be modified to be more explicit about setting apiBase when using codestral

This make the default configuration not working out of the box.
This issue is not present in 0.9.241 and was introduced in 0.9.242.

(with 0.9.241, there is no need to set apiBase in tabAutocompleteModel)

To reproduce

1. Install continue >= 0.9.242
2. rm ~/.continue/config.json to force a default config
3. set your codestral apiKey
4. ask for completion by writing code
