Qwen3.6-35B-A3B — MLX VQ (trained-codebook) @2.6 bpw, custom Metal kernel

Vector-quantized (AQLM-style, trained codebooks + GPTQ compensation) MLX build of Qwen/Qwen3.6-35B-A3B — to our knowledge the first trained-codebook VQ model served on Apple Silicon, via the bundled mx.fast.metal_kernel implementation (code/). 11.53 GB, measurably better than scalar quantization at the same size.

⚠️ Not loadable by stock mlx-lm / LM Studio / Ollama / oMLX — the experts use a VQ format that needs the bundled loader + Metal kernel (~400 lines of Python, mlx>=0.31 only, no compilation).

The scalar-vs-VQ tradeoff this build wins

build	size	think-ja PPL vs bf16	multilingual
GPTQ-3.5bpw (scalar)	15.35 GB	+6.6%	+6.9%
GPTQ-2.7bpw (scalar)	12.03 GB	+17.5%	+15.4%
VQ-2.4bpw — for 16 GB Macs	10.49 GB	+19.5%	+21.6%
this (VQ)	11.53 GB	+12.4%	+12.2%

Smaller and significantly better than the scalar 2.7bpw build — the point of codebook quantization at low bits.

Recipe

Experts (91.7% of params): per-(layer,tensor) bits {2bit: 69, 3bit: 11 tensors} chosen by Fisher/gxw MCKP; Qwen-native codebooks (d=4, K=256 / K=4096; k-means on group-normalized subvectors — GLM-fit books measurably transfer worse, so refit); GPTQ error compensation (pooled per-layer input Hessians, ja-centric calibration). Expert avg 2.38 bpw + fp16 group scales.
Spine: GPTQ 4bit gs64 (linear-attention qkv/z/out, attention q/k/v/o, shared experts), lm_head 6bit, routers 8bit, embeddings 4bit — inherited from the 2.7bpw scalar build.
Vision tower: unquantized bf16.
Format: switch_mlp.*.vq_codes (LSB-first packed 8/12-bit indices, int32) + vq_scales (fp16 per-128 group) + vq_codebooks.safetensors; metadata in config.json["vq"].

Speed (M-series, measured on 48 GB)

decode ~66 tok/s, prefill ~213 tok/s — fused Metal kernels (gate+up+SiLU in one dispatch; simdgroup-per-row GEMV with half4 loads).

Run (Apple Silicon, ≥16 GB unified memory)
