Candidate release — Mac Metal acceptance is pending. Linux native MLX validation passed. Mac inference, performance and broad model quality remain unverified.
Format
File size is not the unified-memory requirement. Leave room for the operating system, KV cache and runtime buffers. Compare the 3-bit, 4-bit, 6-bit and 8-bit candidates in the MLX collection.
Try with mlx-lm
On Apple Silicon, install the versions used to create this export. The following is a usage recipe awaiting Mac Metal acceptance:
Start a local API
The stock CLI options below were checked with mlx-lm 0.31.3. Mac Metal acceptance remains pending. HTTP inference checks for this release are recorded only for the new 6-bit and 8-bit exports.
In a second terminal:
Client base URL: http://127.0.0.1:8000/v1. Inference runs on your machine.
Conversion and validation
A lossless adapter stacks separate expert weights in numeric expert order before invoking the Qwen3.5 sanitizer exactly once. Quantization and serialization use native APIs; reload uses the stock loader without an adapter.
Passed Linux checks: strict stock reload; complete stored floating-value checks; native dequantization of every quantized row; tokenizer/template comparison; and one bounded cached greedy CPU generation with finite logits. The prompt “Compute 2+2. Answer briefly.” returned 4. This is a limited smoke test, not a quality benchmark or a Mac runtime result.
