Quantized for local Mac inference (Apple Silicon / Metal) by worthdoing

About

This is a GGUF quantized version of Qwen3.6-35B-A3B, optimized for running locally on Apple Silicon Macs with llama.cpp, Ollama, or LM Studio.

  • Original model: Qwen/Qwen3.6-35B-A3B
  • Parameters: 35B
  • Quantized by: worthdoing
  • Pipeline: corelm-model v1.0

Description

Qwen 3.6 MoE model. 35B total, 3B active (256 experts, 8 active). Multimodal with vision support.

Available Quantizations

File Quant BPW Size Use Case
qwen3.6-35b-a3b-Q4_K_M-worthdoing.gguf Q4_K_M 4.58 ~18.7 GB Recommended - Best quality/size ratio
qwen3.6-35b-a3b-Q5_K_M-worthdoing.gguf Q5_K_M 5.33 ~21.7 GB Higher quality, still fast

  2. Open LM Studio -> My Models -> Import
  3. Select the GGUF file and start chatting

Quantization Method

Our quantization pipeline (corelm-model v1.0) follows a rigorous multi-step process to ensure maximum quality and compatibility:

Step 1 — Download & Validation

  • Model weights are downloaded from HuggingFace Hub in SafeTensors format (.safetensors)
  • Legacy formats (.bin, .pt) are excluded to ensure clean, verified weights
  • Tokenizer, configuration, and all metadata are preserved

Step 2 — Conversion to GGUF F16 Baseline

  • The original model is converted to GGUF format at FP16 precision using convert_hf_to_gguf.py from llama.cpp
  • This lossless baseline preserves the full original model quality
  • Architecture-specific tensors (attention, FFN, embeddings, MoE routing) are mapped to their GGUF equivalents

Step 3 — K-Quant Quantization

  • The F16 baseline is quantized using llama-quantize with k-quant methods
  • K-quants use a mixed-precision approach: more important layers (attention, output) retain higher precision, while less sensitive layers (FFN) are compressed more aggressively
  • Each quantization level offers a different quality/size tradeoff:
Method Bits per Weight Strategy
Q4_K_M ~4.58 bpw Mixed 4/5-bit. Attention & output layers use Q5_K, FFN layers use Q4_K. Best balance of quality and size.
Q5_K_M ~5.33 bpw Mixed 5/6-bit. Attention & output layers use Q6_K, FFN layers use Q5_K. Higher quality with moderate size increase.
Q8_0 ~7.96 bpw Uniform 8-bit. All layers quantized to 8-bit. Near-lossless quality, largest file size.

Step 4 — Metadata Injection

  • Custom metadata is embedded directly in each GGUF file:
    • general.quantized_by: worthdoing
    • general.quantization_version: corelm-1.0
  • This ensures full traceability and provenance of every quantized file

Tools & Environment

  • llama.cpp: Used for both conversion and quantization — the industry-standard open-source LLM inference engine
  • Target platform: Apple Silicon Macs (M1/M2/M3/M4) with Metal GPU acceleration
  • Inference runtimes: Compatible with llama.cpp, Ollama, LM Studio, koboldcpp, and any GGUF-compatible runtime

Recommended Hardware

Quant Min RAM Recommended
Q4_K_M 24 GB Mac with 37 GB+ RAM
Q5_K_M 28 GB Mac with 43 GB+ RAM
Q8_0 42 GB Mac with 64 GB+ RAM
