32
+ r"""
33
+ This is the configuration class to store the configuration of a [`XverseModel`]. It is used to instantiate an Xverse
34
+ model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
35
+ defaults will yield a similar configuration to that of the XVERSE-13B.
36
+
37
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
38
+ documentation from [`PretrainedConfig`] for more information.
39
+
40
+
41
+ Args:
42
+ vocab_size (`int`, *optional*, defaults to 100278):
43
+ Vocabulary size of the XVERSE model. Defines the number of different tokens that can be represented by the
44
+ `inputs_ids` passed when calling [`XverseModel`]
45
+ hidden_size (`int`, *optional*, defaults to 5120):
46
+ Dimension of the hidden representations.
47
+ intermediate_size (`int`, *optional*, defaults to 13824):
48
+ Dimension of the MLP representations.
49
+ num_hidden_layers (`int`, *optional*, defaults to 40):
50
+ Number of hidden layers in the Transformer encoder.
51
+ num_attention_heads (`int`, *optional*, defaults to 40):
52
+ Number of attention heads for each attention layer in the Transformer encoder.
53
+ hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
54
+ The non-linear activation function (function or string) in the decoder.
55
+ max_position_embeddings (`int`, *optional*, defaults to 8192):
56
+ The maximum sequence length that this model might ever be used with. Typically set this to something large
57
+ just in case (e.g., 512 or 1024 or 2048).
58
+ initializer_range (`float`, *optional*, defaults to 0.02):
59
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
60
+ rms_norm_eps (`float`, *optional*, defaults to 1e-6):
61
+ The epsilon used by the rms normalization layers.
62
+ use_cache (`bool`, *optional*, defaults to `True`):
63
+ Whether or not the model should return the last key/values attentions (not used by all models). Only
64
+ relevant if `config.is_decoder=True`.
65
+ tie_word_embeddings(`bool`, *optional*, defaults to `False`):
66
+ Whether to tie weight embeddings
67
+
68
+ Example:
69
+
70
+ ```python
71
+ >>> from transformers import XverseModel, XverseConfig
72
+
73
+ >>> # Initializing a Xverse XVERSE-13B style configuration
74
+ >>> configuration = XverseConfig()
75
+
76
+ >>> # Initializing a model from the XVERSE-13B style configuration
77
