Enables fused QKV projections. For self-attention modules, all projection matrices (i.e., query, key, value) are fused. For cross-attention modules, key and value projection matrices are fused.

> This API is 🧪 experimental.

Parameters:

sample_size (int) : The width of the latent images. This is fixed during training since it is used to learn a number of position embeddings.

patch_size (int) : Patch size to turn the input data into small patches.

in_channels (int, optional, defaults to 4) : The number of channels in the input.

num_mmdit_layers (int, optional, defaults to 4) : The number of layers of MMDiT Transformer blocks to use.

num_single_dit_layers (int, optional, defaults to 32) : The number of layers of Transformer blocks to use. These blocks use concatenated image and text representations.

attention_head_dim (int, optional, defaults to 256) : The number of channels in each head.

num_attention_heads (int, optional, defaults to 12) : The number of heads to use for multi-head attention.

joint_attention_dim (int, optional) : The number of encoder_hidden_states dimensions to use.

caption_projection_dim (int) : Number of dimensions to use when projecting the encoder_hidden_states.

out_channels (int, defaults to 4) : Number of output channels.

pos_embed_max_size (int, defaults to 1024) : Maximum positions to embed from the image latents.
