OpenAI model setting

[brichet]

Description

It seems that the modalities setting is always sent when instantiating the openAI models (an empty array if not filled).

Some models complain because this settings should be set (e.g. chatgpt-4o-latest), probably because (1) it needs this settings or (2) it doesn't allow empty array.

Some models cannot be used because of this setting, that it does not allow at all (e.g. o4-mini).

Reproduce

Use one of the model above without setting the modalities.

Suggestion

Do not send optional settings if empty.
