/// A question only OpenAI's own cloud asks. Its models took their instructions as "system" first,
/// then as "developer", and the early reasoning models took none at all, so that the instructions
/// had to travel as a message of the person instead. Every other provider has one way to send a
/// system prompt, and for their models the rules say nothing about this.
///
/// That the vendor's name is not in the members is on purpose: they say what the model accepts,
/// and the provider decides how to spell that in its request.
