Qwen3.6-35B-Abliterated-Claude-4.7-200k โ€” NVFP4 Blackwell GGUF

Architecture-specific format for NVIDIA Blackwell GPUs (sm_120/sm_121).

What is NVFP4?

NVFP4 is a native FP4 quantization format that engages the Blackwell FP4 tensor cores. On a DGX Spark / GB10, this delivers ~23% faster generation compared to Q4_K_M GGUF.

Note: This model has the MTP (Multi-Token Prediction) layer removed to work around a qwen35moe handler bug in Ollama v0.30.11. Normal single-token generation is unaffected.

Performance (GB10 DGX Spark)

Metric Q4_K_M NVFP4 Improvement
Generation 71.42 tok/s 87.65 tok/s +23%
File size 23 GB 19 GB -17%

Requirements

  • Hardware: NVIDIA Blackwell GPU (GB10, RTX 5090, etc.) โ€” sm_120 or sm_121
  • Software: Ollama v0.30.11+ (CUDA v13 backend)
  • Other GPUs: Will fall back to CPU or standard CUDA โ€” not recommended

Usage

ollama pull wickgraveyard/qwen35b-nvfp4-blackwell
ollama run wickgraveyard/qwen35b-nvfp4-blackwell

Conversion Method

This model was converted from Q4_K_M GGUF using llama-quantize with --prune-layers 40 (to remove the MTP layer) and --tensor-type-file for NVFP4 mapping.
