    **Important:** when using JSON mode, you **must** also instruct the model to
    produce JSON yourself via a system or user message. Without this, the model may
    generate an unending stream of whitespace until the generation reaches the token
    limit, resulting in a long-running and seemingly "stuck" request. Also note that
