Qwen3.5-4B-MTP-BF16-GGUF

Qwen3.5-4B (qwen35 dense+ssm hybrid arch) with NextN/MTP head preserved, full bf16 precision (~8.3 GB). Source for further quantization. Built via the patched convert_hf_to_gguf.py from patched llama.cpp build with Qwen3.5/3.6 MTP support.

Files

File	Size	Purpose
`Qwen3.5-4B-MTP-bf16.gguf`	8.3 GB	Full-precision source. NextN tensors at `blk.32`.

Note on outlier weights

This model contains 3 tensors with extreme magnitudes (1e19 to 1e36):

blk.9.ssm_out.weight
blk.15.attn_output.weight
blk.24.ffn_gate.weight

These are genuine learned weights (forward pass numerically OK). They overflow the fp16 scale-block storage of certain k-quants (e.g. Q4_K_M). When quantizing downstream, keep them at bf16 via:

llama-quantize \
  --tensor-type "blk\.9\.ssm_out\.weight=bf16" \
  --tensor-type "blk\.15\.attn_output\.weight=bf16" \
  --tensor-type "blk\.24\.ffn_gate\.weight=bf16" \
  Qwen3.5-4B-MTP-bf16.gguf \
  Qwen3.5-4B-MTP-Q4_K_M.gguf \
  Q4_K_M

IQ4_XS does not need overrides — its imatrix-aware path masks the outliers.

Build pipeline

python convert_hf_to_gguf.py /path/to/Qwen3.5-4B \
    --outfile Qwen3.5-4B-MTP-bf16.gguf

Required adding the qwen35 pre-tokenizer chkhsh entry to convert_hf_to_gguf.py:1531 (vendored in the fork).
