    This is the configuration class to store the configuration of a [`FeynModel`]. It is used to instantiate a FeynModel
    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
    defaults will yield a similar configuration to that of the Gemma2-2B + Florence-2-Base + FeynModel V0.1.0.
