10
+ r"""
11
+ This is the configuration class to store the configuration of a [`DeepseekV3Model`]. It is used to instantiate an DeepSeek
12
+ model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
13
+ defaults will yield a similar configuration to that of the DeepSeek-V3.
14
+
15
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
16
+ documentation from [`PretrainedConfig`] for more information.

+ `inputs_ids` passed when calling [`DeepseekV3Model`]

34
+ Number of attention heads for each attention layer in the Transformer decoder.
35

36
+ Number of shared experts, None means dense model.

47
+ num_experts_per_tok (`int`, *optional*, defaults to None):
48
+ Number of selected experts, None means dense model.
49
+ moe_layer_freq (`int`, *optional*, defaults to 1):

51
+ first_k_dense_replace (`int`, *optional*, defaults to 0):
52

64
+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
65
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
66
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
67
+ by meanpooling all the original heads within that group. For more details checkout [this
68
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
