| class DeepseekV3Config(PretrainedConfig):
|
| r"""
|
| This is the configuration class to store the configuration of a [`DeepseekV3Model`]. It is used to instantiate an DeepSeek
|
| 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 DeepSeek-V3.
|
|
|
| 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 129280):
|
| Vocabulary size of the Deep model. Defines the number of different tokens that can be represented by the
|
| `inputs_ids` passed when calling [`DeepseekV3Model`]
|
| hidden_size (`int`, *optional*, defaults to 4096):
|
| Dimension of the hidden representations.

|
| Number of hidden layers in the Transformer decoder.

|
| Number of nextn predict layers in the DeepSeekV3 Model.
|
| num_attention_heads (`int`, *optional*, defaults to 32):
|
| Number of attention heads for each attention layer in the Transformer decoder.
|
| n_shared_experts (`int`, *optional*, defaults to None):
|
| Number of shared experts, None means dense model.
|
| n_routed_experts (`int`, *optional*, defaults to None):
|
| Number of routed experts, None means dense model.
|
| routed_scaling_factor (`float`, *optional*, defaults to 1.0):
|
| Scaling factor or routed experts.
|
| topk_method (`str`, *optional*, defaults to `gready`):
|
| Topk method used in routed gate.
|
| n_group (`int`, *optional*, defaults to None):
|
| Number of groups for routed experts.
|
| topk_group (`int`, *optional*, defaults to None):
|
| Number of selected groups for each token(for each token, ensuring the selected experts is only within `topk_group` groups).
|
| num_experts_per_tok (`int`, *optional*, defaults to None):
|
| Number of selected experts, None means dense model.
|
| moe_layer_freq (`int`, *optional*, defaults to 1):
|
| The frequency of the MoE layer: one expert layer for every `moe_layer_freq - 1` dense layers.
|
| first_k_dense_replace (`int`, *optional*, defaults to 0):
|
| Number of dense layers in shallow layers(embed->dense->dense->...->dense->moe->moe...->lm_head).

|
| Whether to compute the auxiliary loss for each individual sample.
|
| 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.
|

|
| 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.

|
| 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/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):
|

| 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.

|
| Whether to use a bias in the query, key, value and output projection layers during self-attention.
|
