Nvidia-Qwen3.6-27B-NVFP4 - GGUF

Quantized GGUF versions of nvidia/Qwen3.6-27B-NVFP4. These were generated using llama.cpp (b9859).

Nvidia-Qwen3.6-27B-NVFP4-A.gguf: The FFN and attention layers are NVFP4 quantized. The MTP draft layer is preserved at BF16. This was generated from BF16-Attn using a modified llama-quantize to re-quantize the BF16-upcast attention layers to NVFP4.
Nvidia-Qwen3.6-27B-NVFP4-BF16-Attn.gguf: The NVFP4 FFN layers are preserved, while the FP8 attention layers are upcast to BF16. This is the default conversion for BF16 because GGUF files do not support FP8. This was generated using convert_hf_to_gguf.py.

Quantizations provided

File	Quantization	Size
Nvidia-Qwen3.6-27B-NVFP4-A.gguf	NVFP4 FFN and attention	17.9 GB
Nvidia-Qwen3.6-27B-NVFP4-BF16-Attn.gguf	NVFP4 FFN, BF16 attention	28.2 GB

Perplexity test

I tested perplexity using llama-perplexity and Salesforce's wikitext-2-raw-v1.

File	Ctx	PPL
Nvidia-Qwen3.6-27B-NVFP4-A.gguf	512	7.6619 ± 0.05299
Nvidia-Qwen3.6-27B-NVFP4-BF16-Attn.gguf	512	7.4814 ± 0.05157

Evaluation

The following models were evaluated for a fair comparison of capability, size and speed.

Model	Quantization	Size	Reason
unsloth/Qwen3.6-27B-MTP-GGUF	UD-Q4_K_XL	17.9 GB	Closest non-NVFP4 in size to NVFP4.
unsloth/Qwen3.6-27B-MTP-GGUF	UD-Q6_K_XL	26 GB	Closest non-NVFP4 in size to BF16-Attn.
unsloth/Qwen3.6-27B-NVFP4	NVFP4¹	25.4 GB	Alternative NVFP4 quant.

1: unsloth/Qwen3.6-27B-NVFP4 does not provide a GGUF. I used llama.cpp's conversion which passes through Unsloth's NVFP4 tensors.
