Qwen3.8-27B-MTP-bf16

This is the MTP (multi-token-prediction) head of Qwen/Qwen3.8-27B.

The official model contains this head as 15 mtp.* tensors. We copied these 15 tensors from revision 1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0. We removed the mtp. prefix from each tensor name. Example: mtp.fc.weight is now fc.weight. We did not train the weights. We did not change the weights. The data type is bfloat16, the same as the official release.

Contents

• One fusion projection (fc.weight).
• One transformer layer with its norms.
• config.json with model_type: qwen3_5_mtp and block_size: 3.
• model.safetensors.index.json. Loaders read the head as its own model tree, so these two files are necessary.

This is not a standalone model

The head predicts draft tokens from the hidden states of its base model. It cannot generate text alone. Use it with the 4-bit reference model: EigenLabs/Qwen3.8-27B-4bit.

Role

The Qwen 3.8 MTP challenge uses this head for speculative decoding. The track is qwen3.8-27b-mtp-v1. The challenge repository is Layr-Labs/qwen-3.8-mtp-challenge. The challenge points to one fixed revision of this repository.
