class Exaone4Config(PreTrainedConfig):
|
|
r"""
|
|
This is the configuration class to store the configuration of a [`Exaone4Model`]. It is used to
|
|
instantiate a EXAONE 4.0 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 EXAONE-4.0-32B [LGAI-EXAONE/EXAONE-4.0-32B](https://huggingface.co/LGAI-EXAONE/EXAONE-4.0-32B)
|
|
|
|
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 102400):
|
|
Vocabulary size of the EXAONE 4.0 model. Defines the number of different tokens that can be represented by the
|
|
`inputs_ids` passed when calling [`Exaone4Model`].
|
|
hidden_size (`int`, *optional*, defaults to 4096):
|
|
Dimension of the hidden representations.
|
|
intermediate_size (`int`, *optional*, defaults to `hidden_size * 4`):
|
|
Dimensionality of the MLP representations.
|
|
num_hidden_layers (`int`, *optional*, defaults to 32):
|
|
Number of hidden layers in the Transformer encoder.
|
|
num_attention_heads (`int`, *optional*, defaults to 32):
|
|
Number of attention heads for each attention layer in the Transformer decoder.
|
|
num_key_value_heads (`int`, *optional*):
|
|
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://huggingface.co/papers/2305.13245). If it is not specified, will default to
|
|
`num_attention_heads`.
|
|
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
|
The non-linear activation function (function or string) in the decoder.
|
|
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., 32768 for EXAONE 3.5).
|
|
initializer_range (`float`, *optional*, defaults to 0.02):
|
|
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
|
rms_norm_eps (`float`, *optional*, defaults to 1e-05):
|
|
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``.
|
|
bos_token_id (`int`, *optional*, defaults to 0):
|
|
Beginning of stream token id.
|
|
eos_token_id (`int`, *optional*, defaults to 2):
|
|
End of stream token id.
|
|
pad_token_id (`int`, *optional*):
|
|
The id of the padding token.
|
|
tie_word_embeddings (`bool`, *optional*, defaults to `False`):
|
|
Whether to tie weight embeddings
|
|
rope_parameters (`RopeParameters`, *optional*):
|
|
Dictionary containing the configuration parameters for the RoPE embeddings. The dictionary should contain
|
|
a value for `rope_theta` and optionally parameters used for scaling in case you want to use RoPE
|
|
with longer `max_position_embeddings`.
|
|
attention_dropout (`float`, *optional*, defaults to 0.0):
|
|
The dropout ratio for the attention probabilities.
|
|
sliding_window (`int`, *optional*):
|
|
The size of the sliding window for the sliding window attention.
|
|
sliding_window_pattern (`str`, *optional*):
|
|
The pattern to use for sliding window attention. Can be one of:
|
|
- `None`: No sliding window attention is used
|
|
- `int`: Every `sliding_window` layers, use global attention, else use local attention.
|
|
- `str`: A sequence of "L" (local attention) and "G" (global attention) characters that defines the
|
|
attention pattern. The pattern starts from layer 0 and repeats every `sliding_window` layers. The
|
|
final layer always uses global attention regardless of the pattern.
|
|
For instance, sliding_window_pattern="LLLG" same as sliding_window=4, which means:
|
|
- Layer 0, 1, 2: local attention,
|
|
- Layer 3: global attention,
|
|
...(repeated)
|
|
layer_types (`list`, *optional*):
|
|
Attention pattern for each layer. Prioritized over `sliding_window_pattern`.
|
|
|
|
Example:
|
|
|
|
```python
|
|
>>> from transformers import Exaone4Model, Exaone4Config
|
|
|
|
>>> # Initializing a EXAONE configuration
|
|
>>> configuration = Exaone4Config()
|
|
|
|
>>> # Initializing a model from configuration
|
|
>>> model = Exaone4Model(configuration)
|
|
|
|
>>> # Accessing the model configuration
|
|
>>> configuration = model.config
