where is the mtp?

[jamesben6688]

Hi,

I found the MTP config:

"mtp_num_hidden_layers": 1,
"mtp_use_dedicated_embeddings": false,

However, it seems that MTP is not implemented in https://github.com/huggingface/transformers/blob/main/src/transformers/models/qwen3_5/modeling_qwen3_5.py?

May I know where the mtp was implemented and used?
