	# AX Qwen3 Coder Next MLX 4-bit

	> Parameter count: approximately 79.67B logical parameters (80B total,
	> 3B active per token). `4-bit` is the quantization precision, not a 4B
	> model-size claim.

	This is a revision-pinned, transparent mirror of
	[mlx-community/Qwen3-Coder-Next-4bit](https://huggingface.co/mlx-community/Qwen3-Coder-Next-4bit)
	at commit `7b9321eabb85ce79625cac3f61ea691e4ea984b5`.

	The model weights, index, configuration, tokenizer, chat template, generation
	configuration, and tool-parser files are byte-identical to that upstream
	revision. AutomatosX did not fine-tune, merge, re-quantize, or otherwise alter
	the model artifacts. We add only mirror documentation, a copy of the declared
	Apache 2.0 license, and machine-readable provenance.

	## Model details

	- Base model: [Qwen/Qwen3-Coder-Next](https://huggingface.co/Qwen/Qwen3-Coder-Next)
	- Format: MLX Safetensors for Apple Silicon
	- Architecture: Qwen3NextForCausalLM, mixture of experts
	- Main quantization: 4-bit affine, group size 64
	- Quantization exceptions: router and shared-expert gate tensors remain 8-bit,
	as defined by the unchanged upstream config
	- Layers: 48
	- Experts: 512 total, 10 selected per token
	- Configured context limit: 262,144 tokens
	- Weight shards: 9, totaling 44,844,286,500 bytes
	- Upstream conversion tool: mlx-lm 0.30.5

	## Download

	~~~bash
	hf download AutomatosX/AX-Qwen3-Coder-Next-MLX-4bit \
	--local-dir ./AX-Qwen3-Coder-Next-MLX-4bit
	~~~

	## Use with MLX-LM

	~~~bash
	pip install mlx-lm
	mlx_lm.generate \
	--model AutomatosX/AX-Qwen3-Coder-Next-MLX-4bit \
	--prompt "Write a Python function that merges two sorted lists."
	~~~

	Applications should apply the included chat template for conversational or
	tool-using prompts.

	## Serve with AX Engine

	You can also serve the downloaded model through the OpenAI-compatible API in
	[AX Engine](https://github.com/defai-digital/ax-engine):

	~~~bash
	ax-engine serve ./AX-Qwen3-Coder-Next-MLX-4bit --port 31418
	~~~

	## Mirror policy and provenance

	This release is meant to group a required upstream artifact under the
	AutomatosX catalog, not to claim a new conversion. `UPSTREAM_README.md`
	preserves the original upstream model card. `ax_provenance.json` pins the
	source commit and records SHA-256 values and sizes for every mirrored artifact.

	The local Hugging Face cache contained an AX-generated `model-manifest.json`;
	it is not present in the pinned upstream repository and was deliberately not
	published here.

	This is a standard direct-decoding model. It does not contain an MTP head and
	no MTP conversion was applied.

	## License

	The upstream model metadata declares Apache License 2.0. See `LICENSE`, the
	upstream model card, and the base-model card for limitations and responsible-use
	guidance.
