        ``supported_efforts`` lists the discrete effort levels the model accepts
        (e.g.

        ``["low", "medium", "high"]`` for OpenAI o-series). Empty for
        token-budget

        models such as Anthropic extended thinking and Gemini thinking, and for
        models

        that do not reason. ``default_effort`` is the effort applied when the
        request

        omits ``reasoning_effort``; ``null`` when the model has no discrete
        default.
