r"""
This is the configuration class to store the configuration of a [`ArcticModel`]. It is used to instantiate an
Arctic 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 #TODO(rsamdani): add what model has the default config..
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 32000):
Vocabulary size of the Arctic model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`ArcticModel`]
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the hidden representations.
intermediate_size (`int`, *optional*, defaults to 14336):

Number of attention heads for each attention layer in the Transformer encoder.
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`.
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 `4096*32`):

allows sequence of up to 4096*32 tokens.
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 rms 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`.
pad_token_id (`int`, *optional*):
The id of the padding token.
bos_token_id (`int`, *optional*, defaults to 1):
The id of the "beginning-of-sequence" token.

The dropout ratio for the attention probabilities.
num_experts_per_tok (`int`, *optional*, defaults to 2):
The number of experts to root per-token, can be also interpreted as the `top-p` routing
parameter

class ExaoneConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a :class:
`~transformers.ExaoneModel`. It is used to instantiate a GPT Lingvo 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
Configuration objects inherit from {class}`~transformers.PretrainedConfig`
and can be used to control the model outputs. Read the documentation from :
class:`~transformers.PretrainedConfig` for more information.
Args:
vocab_size ({obj}`int`, `optional`, defaults to 50257):
Vocabulary size of the GPT Lingvo model. Defines the number of
different tokens that can be represented by the {obj}`inputs_ids`
passed when calling {class}`~transformers.ExaoneModel`. Vocabulary
size of the model.
Defines the different tokens that can be represented by the
`inputs_ids` passed to the forward method of :class:
`~transformers.EXAONEModel`.
hidden_size ({obj}`int`, `optional`, defaults to 2048):
Dimensionality of the encoder layers and the pooler layer.
num_layers ({obj}`int`, `optional`, defaults to 24):
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://arxiv.org/pdf/2305.13245.pdf). If it is not
specified, will default to `num_attention_heads`.
rotary_pct (`float`, *optional*, defaults to 0.25):
percentage of hidden dimensions to allocate to rotary embeddings
intermediate_size ({obj}`int`, `optional`, defaults to 8192):
Dimensionality of the "intermediate" (i.e., feed-forward) layer in
the Transformer encoder.
activation_function ({obj}`str` or {obj}`function`, `optional`,
defaults to {obj}`"gelu_new"`):
The non-linear activation function (function or string) in the
encoder and pooler. If string, {obj}`"gelu"`, {obj}`"relu"`,
{obj}`"selu"` and {obj}`"gelu_new"` are supported.
embed_dropout ({obj}`float`, `optional`, defaults to 0.0):
The dropout probabilitiy for all fully connected layers in the
embeddings, encoder, and pooler.
attention_dropout ({obj}`float`, `optional`, defaults to 0.0):
The dropout ratio for the attention probabilities.
max_position_embeddings ({obj}`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., 512 or 1024 or 2048).
type_vocab_size ({obj}`int`, `optional`, defaults to 2):
The vocabulary size of the {obj}`token_type_ids` passed when calling
{class}`~transformers.EXAONEModel`.
initializer_range ({obj}`float`, `optional`, defaults to 0.02):
The standard deviation of the truncated_normal_initializer for
initializing all weight matrices.
layer_norm_epsilon ({obj}`float`, `optional`, defaults to 1e-5):
The epsilon used by the layer normalization layers.
use_cache ({obj}`bool`, `optional`, defaults to {obj}`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``.
gradient_checkpointing ({obj}`bool`, `optional`,
defaults to {obj}`False`):
If True, use gradient checkpointing to save memory at the expense
of slower backward pass.
Example::
>>> from transformers import ExoneModel, ExaoneConfig
>>> # Initializing a EXAONE configuration
>>> configuration = ExaoneConfig()
>>> # Initializing a model from configuration
>>> model = ExoneModel(configuration)
>>> # Accessing the model configuration

logger = logging.get_logger(__name__)
class JAISConfig(PretrainedConfig):
"""
This is the configuration class to store the configuration of a
[`JAISModel`]. It is used to instantiate a JAIS model according to the
specified arguments, defining the model 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 50257):
Vocabulary size of the JAIS model. Defines the number of different
tokens that can be represented by the
`inputs_ids` passed when calling [`JAISModel`].
n_positions (`int`, *optional*, defaults to 1024):
The maximum sequence length that this model might ever be used
with. Typically set this to something large just in case
(e.g., 512 or 1024 or 2048).
n_embd (`int`, *optional*, defaults to 768):
Dimensionality of the embeddings and hidden states.
n_layer (`int`, *optional*, defaults to 12):
Number of hidden layers in the Transformer encoder.
n_head (`int`, *optional*, defaults to 12):
Number of attention heads for each attention layer in the
Transformer encoder.
n_inner (`int`, *optional*, defaults to None):
Dimensionality of the inner feed-forward layers. `None` will set
it to 4 times n_embd
activation_function (`str`, *optional*, defaults to `"gelu"`):
Activation function, to be selected in the list
`["relu", "silu", "gelu", "tanh", "gelu_new", "swiglu"]`.
resid_pdrop (`float`, *optional*, defaults to 0.1):
The dropout probability for all fully connected layers in
the embeddings, encoder, and pooler.
embd_pdrop (`float`, *optional*, defaults to 0.1):
The dropout ratio for the embeddings.
attn_pdrop (`float`, *optional*, defaults to 0.1):
The dropout ratio for the attention.
layer_norm_epsilon (`float`, *optional*, defaults to 1e-5):
The epsilon to use in the layer normalization layers.
initializer_range (`float`, *optional*, defaults to 0.02):
The standard deviation of the truncated_normal_initializer for
initializing all weight matrices.
scale_attn_weights (`bool`, *optional*, defaults to `True`):
Scale attention weights by dividing by sqrt(hidden_size)..
use_cache (`bool`, *optional*, defaults to `True`):
Whether or not the model should return the last key/values
attentions (not used by all models).
scale_attn_by_inverse_layer_idx (`bool`, *optional*,
defaults to `False`):
Whether to additionally scale attention weights by
`1 / layer_idx + 1`.
reorder_and_upcast_attn (`bool`, *optional*, defaults to `False`):
Whether to scale keys (K) prior to computing attention
(dot-product)
and upcast attention dot-product/softmax to float() when training
with mixed precision.
position_embedding_type (`str`, *optional*, defaults to `"learned"`):
Positional embedding can be either `"alibi"` or `"learned"`.
mup_width_scale (`float`, *optional*, defaults to 1.0):
muP parameter to scale learning rate and initializers. Calculated
as (`d_model,0 / d_model`), where
`d_model` is the model's width and `d_model,0` is the proxy
model's width.
mup_embeddings_scale (`float`, *optional*, defaults to 1.0):
muP parameter to scale token and position embeddings.
mup_output_alpha (`float`, *optional*, defaults to 1.0):
muP parameter to scale output logits
(`output_logits_scale = mup_output_alpha * mup_width_scale`).
mup_scale_qk_dot_by_d (`bool`, *optional*, defaults to `False`):
Scale attention weights by dividing by hidden_size instead of
sqrt(hidden_size). Need to set scale_attn_weights to `True` as
well.
alibi_scaling (`dict`, *optional*):
Dictionary containing the scaling configuration for ALiBi
embeddings. Currently only supports linear
scaling strategy. Can specify either the scaling `factor` (must be
a float greater than 1) for fixed scaling
or `train_seq_len` for dynamic scaling on input samples with
sequence length > `train_seq_len`. The expected
formats are `{"type": strategy name, "factor": scaling factor}` or
`{"type": strategy name,
"train_seq_len": training sequence length}`.
architectures (`list`, *optional*, defaults to ['JAISLMHeadModel']):
architecture names for Jais.
Example:
```python
>>> from transformers import JAISConfig, JAISModel
>>> # Initializing a JAIS configuration
>>> configuration = JAISConfig()
>>> # Initializing a model (with random weights) from the configuration
>>> model = JAISModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config

"""Nemotron model configuration"""
from transformers import PretrainedConfig
from transformers.utils import logging
logger = logging.get_logger(__name__)
class NemotronConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a
[`NemotronModel`]. It is used to instantiate an Nemotron 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 Nemotron-8B.
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 256000):
Vocabulary size of the Nemotron model. Defines the number of
different tokens that can be represented by the
`inputs_ids` passed when calling [`NemotronModel`]
hidden_size (`int`, *optional*, defaults to 6144):
Dimension of the hidden representations.
intermediate_size (`int`, *optional*, defaults to 24576):

(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 `num_attention_heads`.
hidden_act (`str` or `function`, *optional*, defaults to `"relu2"`):

The standard deviation of the truncated_normal_initializer for
initializing all weight matrices.

The epsilon used by the 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`.

Whether to use a bias in up_proj and down_proj layers in the MLP
layers.

"""Solar model configuration"""
from transformers import PretrainedConfig
from transformers.utils import logging
logger = logging.get_logger(__name__)
class SolarConfig(PretrainedConfig):
r"""
This is the configuration class to store
the configuration of a [`SolarModel`].
It is used to instantiate an LLaMA 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 LLaMA-7B.
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 32000):
Vocabulary size of the LLaMA model.
Defines the number of different tokens
that can be represented by the `inputs_ids`
passed when calling [`SolarModel`]
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the hidden representations.
intermediate_size (`int`, *optional*, defaults to 11008):
Dimension of the MLP representations.
num_hidden_layers (`int`, *optional*, defaults to 32):
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*):
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
`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.
Solar 1 supports up to 2048 tokens,
Solar 2 up to 4096, CodeSolar up to 16384.
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-06):
The 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 (not used by all models). Only
relevant if `config.is_decoder=True`.
pad_token_id (`int`, *optional*):
Padding token id.
bos_token_id (`int`, *optional*, defaults to 1):
Beginning of stream token id.
eos_token_id (`int`, *optional*, defaults to 2):
End of stream token id.
pretraining_tp (`int`, *optional*, defaults to 1):
Experimental feature. Tensor parallelism rank
used during pretraining.
Please refer to [this
document](https://huggingface.co/docs/
transformers/main/
perf_train_gpu_many#tensor-parallelism)
to understand more about it. This value is
necessary to ensure exact reproducibility
of the pretraining results.
Please refer to [this
issue](https://github.com/pytorch/pytorch/issues/76232).
tie_word_embeddings (`bool`, *optional*, defaults to `False`):
Whether to tie weight embeddings
rope_theta (`float`, *optional*, defaults to 10000.0):
The base period of the RoPE embeddings.
rope_scaling (`dict`, *optional*):
Dictionary containing the scaling configuration for
the RoPE embeddings.
Currently supports two scaling
strategies: linear and dynamic.
Their scaling factor must be a float greater than 1.
The expected format is
`{"type": strategy name, "factor": scaling factor}`.
When using this flag, don't update
`max_position_embeddings` to the expected new maximum.
See the following thread for more information on how
these scaling strategies behave:
https://www.reddit.com/r/LocalLLaMA/comments/14mrgpr/
dynamically_scaled_rope_further_increases/. This is an
experimental feature, subject to breaking
API changes in future versions.
attention_bias (`bool`, *optional*, defaults to `False`):
Whether to use a bias in the query, key, value
and output projection layers during self-attention.
attention_dropout (`float`, *optional*, defaults to 0.0):
The dropout ratio for the attention probabilities.
mlp_bias (`bool`, *optional*, defaults to `False`):
Whether to use a bias in up_proj, down_proj and gate_proj
layers in the MLP layers.
sliding_window (`int`, *optional*, defaults to 2047):
Sliding window attention window size. If not specified,
will default to `2047`.
