-class FalconConfig(PretrainedConfig):
-    r"""
-    This is the configuration class to store the configuration of a [`FalconModel`]. It is used to instantiate a Falcon
-    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
-    [tiiuae/falcon-7b](https://huggingface.co/tiiuae/falcon-7b) 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 65024):
-            Vocabulary size of the Falcon model. Defines the number of different tokens that can be represented by the
-            `inputs_ids` passed when calling [`FalconModel`]
-        hidden_size (`int`, *optional*, defaults to 4544):
-            Dimension of the hidden representations.
-        num_hidden_layers (`int`, *optional*, defaults to 32):
-            Number of hidden layers in the Transformer decoder.
-        num_attention_heads (`int`, *optional*, defaults to 71):
-            Number of attention heads for each attention layer in the Transformer encoder.
-        initializer_range (`float`, *optional*, defaults to 0.02):
-            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
-        use_cache (`bool`, *optional*, defaults to `True`):
-            Whether the model should return the last key/values attentions (not used by all models). Only relevant if
-            `config.is_decoder=True`.
-        layer_norm_epsilon (`float`, *optional*, defaults to 1e-5):
-            The epsilon used by the layer normalization layers.
-        hidden_dropout (`float`, *optional*, defaults to 0.0):
-            The dropout probability for MLP layers.
-        attention_dropout (`float`, *optional*, defaults to 0.0):
-            The dropout probability for attention layers.
-        num_kv_heads (`int`, *optional*):
-            Number of key-value heads to use per attention layer. If unset, defaults to the same value as
-            `num_attention_heads`.
-        alibi (`bool`, *optional*, defaults to `False`):
-            Whether to use ALiBi positional biases during self-attention.
-        new_decoder_architecture (`bool`, *optional*, defaults to `False`):
-            Whether to use the new (Falcon-40B) decoder architecture. If `True`, the `multi_query` and `parallel_attn`
-            arguments are ignored, as the new decoder always uses parallel attention.
-        multi_query (`bool`, *optional*, defaults to `True`):
-            Whether to use multi-query attention in the decoder. Ignored when `new_decoder_architecture` is `True`.
-        parallel_attn (`bool`, *optional*, defaults to `True`):
-            Whether to compute attention in parallel with the feedforward layer. If False, they are consecutive
-            instead, as in the original Transformer architecture. Ignored when `new_decoder_architecture` is `True`.
-        bias (`bool`, *optional*, defaults to `False`):
-            Whether to use bias on Linear layers.
-        bos_token_id (`int`, *optional*, defaults to 11):
-            The id of the "beginning-of-sequence" token.
-        eos_token_id (`int`, *optional*, defaults to 11):
-            The id of the "end-of-sequence" token.
-    Example:
-    ```python
-    >>> from transformers import FalconModel, FalconConfig
-    >>> # Initializing a small (2-layer) Falcon configuration
-    >>> configuration = FalconConfig(num_hidden_layers=2)
-    >>> # Initializing a model from the small configuration
-    >>> model = FalconModel(configuration)
-    >>> # Accessing the model configuration
-    >>> configuration = model.config
