class GeoVConfig(PretrainedConfig):
    r"""
    This is the configuration class to store the configuration of a [`GeoVModel`]. It is used to instantiate a
    GeoV 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 GeoV
    [GeoV/GeoV-9b](https://huggingface.co/GeoV/GeoV-9b) architecture.

    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
    documentation from [`PretrainedConfig`] for more information.


    Args:
        vocab_size (`int`, *optional*, defaults to 65536):
            Vocabulary size of the GeoV model. Defines the number of different tokens that can be represented by the
            `inputs_ids` passed when calling [`GeoVModel`].
        hidden_size (`int`, *optional*, defaults to 5120):
            Dimension of the encoder layers and the pooler layer.
        num_hidden_layers (`int`, *optional*, defaults to 32):
            Number of hidden layers in the Transformer encoder.
        num_attention_heads (`int`, *optional*, defaults to 40):
            Number of attention heads for each attention layer in the Transformer encoder.
        intermediate_size (`int`, *optional*, defaults to 20480):
            Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
        rotary_emb_base (`int`, *optional*, defaults to 10000)
            base for computing rotary embeddings frequency
        max_position_embeddings (`int`, *optional*, defaults to 2048):
            The maximum sequence length that this model might ever be used with. Typically set this to something large
            just in case (e.g., 512 or 1024 or 2048).
        layer_norm_eps (`float`, *optional*, defaults to 1e-4):
            The epsilon used by the layer normalization layers.
        use_cache (`bool`, *optional*, defaults to `True`):
            Whether or not the model should return the last key/values attentions (not used by all models). Only
            relevant if `config.is_decoder=True`.
        use_extra_biases_ffn (`bool`, *optional*, defaults to `False`):
            Whether or not to have extra bias parameters in the final layer of FFN modules.
        Example:

    ```python
    >>> from transformers import GeoVConfig, GeoVModel

    >>> # Initializing a GeoV configuration
    >>> configuration = GeoVConfig()

    >>> # Initializing a model (with random weights) from the configuration
    >>> model = GeoVModel(configuration)  # doctest: +SKIP

    >>> # Accessing the model configuration
    >>> configuration = model.config  # doctest: +SKIP
