+class MimiConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of an [`MimiModel`]. It is used to instantiate a
+    Mimi 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
+    [kyutai/mimi](https://huggingface.co/kyutai/mimi) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+

+        frame_rate (`float`, *optional*, defaults to 12.5):
+            Framerate of the model.
+        audio_channels (`int`, *optional*, defaults to 1):
+            Number of channels in the audio data. Either 1 for mono or 2 for stereo.
+        hidden_size (`int`, *optional*, defaults to 512):

+            Number of residual layers.
+        upsampling_ratios (`Sequence[int]`, *optional*):
+            Kernel size and stride ratios. The encoder uses downsampling ratios instead of upsampling ratios, hence it
+            will use the ratios in the reverse order to the ones specified here that must match the decoder order.
+            If not specified, will defaults to `[8, 6, 5, 4]`
+        kernel_size (`int`, *optional*, defaults to 7):
+            Kernel size for the initial convolution.
+        last_kernel_size (`int`, *optional*, defaults to 3):

+        dilation_growth_rate (`int`, *optional*, defaults to 2):
+            How much to increase the dilation with each layer.
+        use_causal_conv (`bool`, *optional*, defaults to `True`):
+            Whether to use fully causal convolution.
+        pad_mode (`str`, *optional*, defaults to `"constant"`):
+            Padding mode for the convolutions.
+        compress (`int`, *optional*, defaults to 2):
+            Reduced dimensionality in residual branches.
+        trim_right_ratio (`float`, *optional*, defaults to 1.0):
+            Ratio for trimming at the right of the transposed convolution under the `use_causal_conv = True` setup. If
+            equal to 1.0, it means that all the trimming is done at the right.
+        codebook_size (`int`, *optional*, defaults to 2048):
+            Number of discret codes in each codebooks.
+        codebook_dim (`int`, *optional*, defaults to 256):
+            Dimension of the unquantized codebook vectors. If not defined, uses `hidden_size`.

+        vector_quantization_hidden_dimension (`int`, *optional*, defaults to 256):
+            Intermediate representation dimension in the residual vector quantization space.
+        num_semantic_quantizers (`int`, *optional*, defaults to 1):
+            Number of semantic quantizer channels, or codebooks, in the semantic quantizer. Must be lower than `num_quantizers`.
+        upsample_groups (`int`, *optional*, defaults to 512):
+            If `frame_rate!=encodec_frame_rate`, indicates the number of groups used in the upsampling operation to go from one rate to another.
+        num_hidden_layers (`int`, *optional*, defaults to 8):
+            Number of hidden layers in the Transformer models.

+        num_key_value_heads (`int`, *optional*, defaults to 8):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `8`.
+        head_dim (`int`, *optional*, defaults to `hidden_size // num_attention_heads`):
+            The attention head dimension.

+        max_position_embeddings (`int`, *optional*, defaults to 8000):
+            The maximum sequence length that this model might ever be used with. Mimi's sliding window attention
+            allows sequence of up to 8000 tokens.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the LayerNorm normalization layers.
+        use_cache (`bool`, *optional*, defaults to `False`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        rope_theta (`float`, *optional*, defaults to 10000.0):
+            The base period of the RoPE embeddings.
+        sliding_window (`int`, *optional*, defaults to 250):
+            Sliding window attention window size. If not specified, will default to `250`.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        layer_scale_initial_scale (`float`, *optional*, defaults to 0.01):
+            Initiale scale of the residual rescaling operation done in the Transformer models.
+        attention_bias (`bool`, defaults to `False`, *optional*, defaults to `False`):
+            Whether to use a bias in the query, key, value and output projection layers during self-attention.
+    Example:
+
+    ```python
+    >>> from transformers import MimiModel, MimiConfig
+
+    >>> # Initializing a "kyutai/mimi" style configuration
+    >>> configuration = MimiConfig()
+
+    >>> # Initializing a model (with random weights) from the "kyutai/mimi" style configuration
+    >>> model = MimiModel(configuration)

+                blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
+                returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.
+
+                Two formats are allowed:
+                - a [`~cache_utils.Cache`] instance;
+                - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
+                shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
+                cache format.
+
+                The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
+                legacy cache format will be returned.
+
+                If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
+                have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
+                of shape `(batch_size, sequence_length)`.
+            use_cache (`bool`, *optional*):
+                If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+                `past_key_values`).
+            output_attentions (`bool`, *optional*):
+                Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+                tensors for more detail.
+            output_hidden_states (`bool`, *optional*):
+                Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+                more detail.
+            return_dict (`bool`, *optional*):

-            cache should not be used.
-        force_download (`bool`, *optional*, defaults to `False`):

-            Whether or not to delete incompletely received file. Attempts to resume the download if such a file exists.

-            The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a
-            git-based system for storing models and other artifacts on hf-mirror.com, so `revision` can be any
-            identifier allowed by git.

-            - a path to a *directory* potentially containing the file.

-            The name of the file to locate in `path_or_repo`.
-        cache_dir (`str` or `os.PathLike`, *optional*):
-            Path to a directory in which a downloaded pretrained model configuration should be cached if the standard
-            cache should not be used.
-        force_download (`bool`, *optional*, defaults to `False`):

-            Whether or not to delete incompletely received file. Attempts to resume the download if such a file exists.
-        proxies (`Dict[str, str]`, *optional*):
-            A dictionary of proxy servers to use by protocol or endpoint, e.g., `{'http': 'foo.bar:3128',
-            'http://hostname': 'foo.bar:4012'}.` The proxies are used on each request.
-        token (`str` or *bool*, *optional*):
-            The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated
-            when running `huggingface-cli login` (stored in `~/.huggingface`).
-        local_files_only (`bool`, *optional*, defaults to `False`):

-            In case the relevant files are located inside a subfolder of the model repo on hf-mirror.com, you can
-            specify the folder name here.
-        repo_type (`str`, *optional*):
-            Specify the repo type (useful when downloading from a space for instance).
