Qwen3.6-35B-A3B-Fast-MXFP4-MOE-GGUF
GGUF MXFP4 MoE quantization of unsloth/Qwen3.6-35B-A3B-NVFP4-Fast, a 35B parameter MoE model with 3B active parameters.
What is the "Fast" Variant?
Unsloth's NVFP4 Fast variant is a speed-optimized quantization that delivers 1.79x faster throughput than other NVFP4 quants. This GGUF extends that optimization to MXFP4 MoE format:
| Variant | MMLU-Pro | GPQA | AIME 2025 |
|---|---|---|---|
| Unsloth NVFP4 Fast | 85.58 | 87.75 | 91.67 |
| Unsloth NVFP4 | 85.85 | 86.74 | 92.29 |
| NVIDIA NVFP4 | 85.60 | 87.12 | 91.88 |
| BF16 | 85.75 | 86.36 | 92.50 |
MXFP4 MoE Format
This quantization uses a hybrid approach for optimal quality:
- Expert weights: MXFP4 (E2M1 microscaling, 4-bit)
- Non-expert weights (attention, embeddings, norms): Q8_0 (8-bit)
MXFP4 is an open standard supported by AMD, NVIDIA, and Microsoft, making it compatible with a wider range of hardware.
About the Model
Qwen3.6-35B-A3B is a multimodal MoE model from Alibaba's Qwen team:
- 35B total parameters, 3B active per token (256 experts, 8 active)
- 40-layer decoder with Gated DeltaNet + full attention hybrid
- 27-layer vision encoder (SigLIP-based) for image/video understanding
- 262K native context (extensible to 1M+ via YaRN)
- Multi-Token Prediction (MTP) for faster speculative decoding
- Agentic coding with SWE-bench Verified 73.4, tool calling support
