class Dots1Config(PreTrainedConfig):
|
|
r"""
|
|
This is the configuration class to store the configuration of a [`Dots1Model`]. It is used to instantiate a
|
|
`dots.llm1` model according to the specified arguments, defining the model architecture. Instantiating a
|
|
configuration with the defaults will yield a similar configuration to that of
|
|
[rednote-hilab/dots.llm1.base](https://huggingface.co/rednote-hilab/dots.llm1.base).
|
|
|
|
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 152064):
|
|
Vocabulary size of the model. Defines the number of different tokens that can be represented by the
|
|
`input_ids` passed when calling [`Dots1Model`].
|
|
hidden_size (`int`, *optional*, defaults to 4608):
|
|
Dimension of the hidden representations.
|
|
intermediate_size (`int`, *optional*, defaults to 10944):
|
|
Dimension of the MLP representations.
|
|
moe_intermediate_size (`int`, *optional*, defaults to 1408):
|
|
Dimension of the MoE representations.
|
|
num_hidden_layers (`int`, *optional*, defaults to 62):
|
|
Number of hidden layers in the Transformer decoder.
|
|
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*, defaults to 32):
|
|
Number of key/value heads for Grouped Query Attention. If `num_key_value_heads=num_attention_heads`, Multi
|
|
Head Attention (MHA) is used. If `num_key_value_heads=1`, Multi Query Attention (MQA) is used. Otherwise,
|
|
Grouped Query Attention (GQA) is used. If not specified, defaults to `num_attention_heads`.
|
|
n_shared_experts (`int`, *optional*, default=None):
|
|
Number of shared experts. None means dense model.
|
|
n_routed_experts (`int`, *optional*, default=None):
|
|
Number of routed experts. None means dense model.
|
|
n_group (`int`, *optional*, defaults to 1):
|
|
Number of groups for routed experts.
|
|
topk_group (`int`, *optional*, defaults to 1):
|
|
Number of selected groups for each token (selected experts only within `topk_group` groups).
|
|
num_experts_per_tok (`int`, *optional*, default=None):
|
|
Number of selected experts. None means dense model.
|
|
first_k_dense_replace (`int`, *optional*, defaults to 0):
|
|
Number of dense layers at the beginning of the model before the first MoE layer.
|
|
norm_topk_prob (`bool`, *optional*, defaults to `False`):
|
|
Whether to normalize the weights of the routed experts.
|
|
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
|
The non-linear activation function (function or string).
|
|
max_position_embeddings (`int`, *optional*, defaults to 2048):
|
|
Maximum sequence length the model might ever be used with.
|
|
initializer_range (`float`, *optional*, defaults to 0.02):
|
|
Standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
|
rms_norm_eps (`float`, *optional*, defaults to 1e-06):
|
|
Epsilon used by the RMS normalization layers.
|
|
use_cache (`bool`, *optional*, defaults to `True`):
|
|
Whether or not the model should return the last key/values attentions. Only relevant if `config.is_decoder=True`.
|

|
|
Whether to tie the input and output word 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_bias (`bool`, *optional*, defaults to `False`):
|
|
Whether to use a bias in the self-attention projections.
|
|
attention_dropout (`float`, *optional*, defaults to 0.0):
|
|
Dropout ratio for the attention probabilities.
|
|
routed_scaling_factor (`float`, *optional*, defaults to 1.0):
|
|
Scaling factor for routed experts.
|
|
sliding_window (`int`, *optional*, defaults to 4096):
|
|
Size of the sliding window for attention. If not specified, defaults to `4096`.
|
|
max_window_layers (`int`, *optional*, defaults to 62):
|
|
The number of layers using full attention. The first `max_window_layers` layers will use full attention, while any
|
|
additional layer afterwards will use SWA (Sliding Window Attention).
|
|
layer_types (`list`, *optional*):
|
|
Attention pattern for each layer.
|
|
pad_token_id (`int`, *optional*):
|
|
Padding token id.
|
|
bos_token_id (`int`, *optional*):
|
|
Beginning of stream token id.
|
|
eos_token_id (`int`, *optional*):
|
|
End of stream token id.
