"""DeepSeekV3 model configuration""" from ...configuration_utils import PretrainedConfig from ...modeling_rope_utils import rope_config_validation DEEPSEEK_PRETRAINED_CONFIG_ARCHIVE_MAP = {} 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. e.g. [bzantium/tiny-deepseek-v3](https://huggingface.co/bzantium/tiny-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 7168): Dimension of the hidden representations. intermediate_size (`int`, *optional*, defaults to 18432): Dimension of the MLP representations. moe_intermediate_size (`int`, *optional*, defaults to 2048): Dimension of the MoE representations. num_hidden_layers (`int`, *optional*, defaults to 61): Number of hidden layers in the Transformer decoder. num_attention_heads (`int`, *optional*, defaults to 128): Number of attention heads for each attention layer in the Transformer decoder. num_key_value_heads (`int`, *optional*, defaults to 128): 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`. n_shared_experts (`int`, *optional*, defaults to 1): Number of shared experts. n_routed_experts (`int`, *optional*, defaults to 256): Number of routed experts. routed_scaling_factor (`float`, *optional*, defaults to 2.5): Scaling factor or routed experts. kv_lora_rank (`int`, *optional*, defaults to 512): Rank of the LoRA matrices for key and value projections. q_lora_rank (`int`, *optional*, defaults to 1536): Rank of the LoRA matrices for query projections. qk_rope_head_dim (`int`, *optional*, defaults to 64): Dimension of the query/key heads that use rotary position embeddings. v_head_dim (`int`, *optional*, defaults to 128): Dimension of the value heads. qk_nope_head_dim (`int`, *optional*, defaults to 128): Dimension of the query/key heads that don't use rotary position embeddings. n_group (`int`, *optional*, defaults to 8): Number of groups for routed experts. topk_group (`int`, *optional*, defaults to 4): 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 8): Number of selected experts, None means dense model. first_k_dense_replace (`int`, *optional*, defaults to 3): Number of dense layers in shallow layers(embed->dense->dense->...->dense->moe->moe...->lm_head). \--k dense layers--/ norm_topk_prob (`bool`, *optional*, defaults to `True`): 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) in the decoder. max_position_embeddings (`int`, *optional*, defaults to 4096): The maximum sequence length that this model might ever be used with. 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 0): Beginning of stream token id. eos_token_id (`int`, *optional*, defaults to 1): 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): 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. rope_interleave (`bool`, *optional*, defaults to `True`): Whether to interleave the rotary position embeddings. attention_bias (`bool`, defaults to `False`, *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. ```python >>> from transformers import DeepseekV3Model, DeepseekV3Config >>> # Initializing a Deepseek-V3 style configuration >>> configuration = DeepseekV3Config() >>> # Accessing the model configuration >>> configuration = model.config ```""" model_type = "deepseek_v3" keys_to_ignore_at_inference = ["past_key_values"] base_model_tp_plan = { # TODO: only replicate attention layers when > first_k_dense_replace "layers.*.mlp.experts.*.gate_proj": "local_colwise", "layers.*.mlp.experts.*.up_proj": "local_colwise", "layers.*.mlp.experts.*.down_proj": "local_rowwise", "layers.*.mlp.experts.*": "local", # each expert is wrapped in a module list "layers.*.mlp.shared_experts.gate_proj": "local_colwise", "layers.*.mlp.shared_experts.up_proj": "local_colwise", "layers.*.mlp.shared_experts.down_proj": "local_rowwise", "layers.*.mlp.shared_experts": "local", "layers.*.mlp.gate_proj": "local_colwise", "layers.*.mlp.up_proj": "local_colwise", "layers.*.mlp.down_proj": "local_rowwise", "layers.*.mlp": "gather", # This is the only moment where results are gathered } base_model_pp_plan = { "embed_tokens": (["input_ids"], ["inputs_embeds"]), "layers": (["hidden_states", "attention_mask"], ["hidden_states"]), "norm": (["hidden_states"], ["hidden_states"]), } def __init__( self, vocab_size=129280, hidden_size=7168, intermediate_size=18432, moe_intermediate_size=2048, num_hidden_layers=61, num_attention_heads=128, num_key_value_heads=128, n_shared_experts=1, n_routed_experts=256, routed_scaling_factor=2.5, kv_lora_rank=512, q_lora_rank=1536, qk_rope_head_dim=64, v_head_dim=128, qk_nope_head_dim=128, n_group=8, topk_group=4, num_experts_per_tok=8, first_k_dense_replace=3, norm_topk_prob=True, hidden_act="silu", max_position_embeddings=4096, initializer_range=0.02, rms_norm_eps=1e-6, use_cache=True, pad_token_id=None, bos_token_id=0, eos_token_id=1, pretraining_tp=1, tie_word_embeddings=False, rope_theta=10000.0, rope_scaling=None, rope_interleave=True, attention_bias=False, attention_dropout=0.0, **kwargs, ): self.vocab_size = vocab_size self.max_position_embeddings = max_position_embeddings self.hidden_size = hidden_size self.intermediate_size = intermediate_size self.moe_intermediate_size = moe_intermediate_size self.num_hidden_layers = num_hidden_layers self.num_attention_heads = num_attention_heads self.n_shared_experts = n_shared_experts self.n_routed_experts = n_routed_experts self.routed_scaling_factor = routed_scaling_factor self.kv_lora_rank = kv_lora_rank self.q_lora_rank = q_lora_rank self.qk_rope_head_dim = qk_rope_head_dim self.v_head_dim = v_head_dim self.qk_nope_head_dim = qk_nope_head_dim self.qk_head_dim = qk_nope_head_dim + qk_rope_head_dim self.head_dim = qk_rope_head_dim self.n_group = n_group self.topk_group = topk_group self.num_experts_per_tok = num_experts_per_tok self.first_k_dense_replace = first_k_dense_replace self.norm_topk_prob = norm_topk_prob self.rope_interleave = rope_interleave # for backward compatibility if num_key_value_heads is None: num_key_value_heads = num_attention_heads self.num_key_value_heads = num_key_value_heads self.hidden_act = hidden_act self.initializer_range = initializer_range self.rms_norm_eps = rms_norm_eps self.pretraining_tp = pretraining_tp self.use_cache = use_cache self.rope_theta = rope_theta self.rope_scaling = rope_scaling self.attention_bias = attention_bias self.attention_dropout = attention_dropout # Validate the correctness of rotary position embeddings parameters # BC: if there is a 'type' field, copy it it to 'rope_type'. if self.rope_scaling is not None and "type" in self.rope_scaling: self.rope_scaling["rope_type"] = self.rope_scaling["type"] rope_config_validation(self) super().__init__( pad_token_id=pad_token_id, bos_token_id=bos_token_id, eos_token_id=eos_token_id, tie_word_embeddings=tie_word_embeddings, **kwargs, ) __all__ = ["DeepseekV3Config"]
