Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled-v2 (MLX 4-bit)
A 4-bit MLX quantization of Jackrong/Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled-v2, optimized for Apple Silicon.
About the Base Model
Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled-v2 is the second iteration of the reasoning-focused Qwen3.5-27B fine-tune. It's built on top of Qwen3.5-27B and fine-tuned with Unsloth using distilled reasoning data from Claude 4.6 Opus. This model has been #1 trending on HuggingFace for 3 weeks.
Key improvements in v2:
- More efficient chain-of-thought generation
- Improved reasoning across science, math, and instruction-following
- Trained on data from Jackrong/Qwen3.5-reasoning-700x
Why MLX?
MLX is Apple's native machine learning framework for Apple Silicon. On an M1 Ultra Mac Studio (128GB), this model runs at 28.9 tokens/sec compared to 19.9 tok/s for the equivalent GGUF Q4KM. That's a 45% speed improvement for free, just by using the right format for your hardware.
Benchmark Results
Controlled test: LM Studio, one model loaded at a time, 10 runs each with different prompts, 512 max tokens.
Hardware: M1 Ultra, 128GB unified memory.
