Configuration objects inherit from [PretrainedConfig] and can be used to control the model outputs. Read the documentation from [PretrainedConfig] for more information.

Parameters

• vocab_size (int, optional, defaults to 151936) – Vocabulary size of the Qwen-2 model. Defines the number of different tokens that can be represented by the inputs_ids passed to the forward method.

• hidden_size (int, optional, defaults to 4096) – Dimensionality of the encoder layers and the pooler layer.

• intermediate_size (int, optional, defaults to 22016) – Dimensionality of the “intermediate” (i.e., feed-forward) layer in the Transformer encoder.

• num_hidden_layers (int, optional, defaults to 32) – 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 encoder.

• num_key_value_heads (int, optional, defaults to 32) – Number of key and value heads for each attention layer in the Transformer encoder.

• hidden_act (str or function, optional, defaults to “silu”) – The non-linear activation function (function or string) to use in the encoder and pooler. If string, “gelu”, “relu”, “swish” and “gelu_new” are supported.

• max_position_embeddings (int, optional, defaults to 32768) – The maximum sequence length that this model might ever be used with. Typically set this to something large just in case (e.g., 2048 or 4096).

• rms_norm_eps (float, optional, defaults to 1e-6) – 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.

• tie_word_embeddings (bool, optional, defaults to False) – Whether to tie the weights of the input embeddings and the output embeddings.

• rope_theta (float, optional, defaults to 10000.0) – The theta value to use for rotary position embeddings.

• sliding_window (int, optional, defaults to 4096) – The sliding window size.

• max_window_layers (int, optional, defaults to 28) – The maximum number of layers to use for the sliding window attention.

• attention_dropout (float, optional, defaults to 0.0) – The dropout ratio for the attention probabilities.

• fcm_max_ratio (float, optional, defaults to 0.0) – The maximum ratio for Flash Attention.

• use_scan_mlp (bool, optional, defaults to False) – Whether to use the scan implementation for the MLP.

• scan_mlp_chunk_size (int, optional, defaults to 1024) – The chunk size to use when scanning the MLP.

• number_rep_kv (int, optional, defaults to 1) – Number of repetitions for the key and value vectors.

• bits (int, optional) – The number of bits to quantize the model to.

• scan_layers (bool, optional, defaults to True) – Whether to use the scan implementation for the layers.
