Qwen3-14b-MLX-Q5

Qwen3-14b-MLX-Q5 is an MLX Q5 checkpoint derived from Qwen/Qwen3-14B, intended for local text generation on Apple Silicon.

Intended use

• Local text generation and chat-style prompting on Apple Silicon
• MLX-LM experimentation with the declared upstream model family
• Offline or operator-controlled inference workflows

Out of scope

• Safety-critical decisions without domain expert review
• Claims of benchmark superiority not backed by published evaluation data
• Non-MLX runtime guarantees; this card documents the shipped HF checkpoint, not every possible serving stack

Training and conversion metadata

Parameter	Value
Repository	LibraxisAI/Qwen3-14b-MLX-Q5
Base model	Qwen/Qwen3-14B
Task	text-generation
Library	mlx
Format	MLX / Apple Silicon checkpoint
Quantization	Q5
Architecture	Qwen3ForCausalLM
Model files	2
Config model_type	qwen3

This card only reports metadata present in the Hugging Face repository, existing card frontmatter, or public config files. Missing benchmark, dataset, or training-run details are left explicit rather than reconstructed.

Tested inference path

**Inference for this checkpoint has been tested with LibraxisAI/mlx-batch-server.**
This is the recommended tested path for operator-controlled local inference on Apple Silicon.

Aspect	Status
Tested runtime	LibraxisAI/mlx-batch-server
Target hardware	Apple Silicon
Inference mode	Local / self-hosted
Hugging Face Hosted Inference	Disabled for this repository (inference: false)

This does not claim compatibility with every possible serving stack. It documents the path that has been exercised for this published checkpoint.

Usage

CLI

pip install mlx-lm

mlx_lm.generate \
  --model LibraxisAI/Qwen3-14b-MLX-Q5 \
  --prompt "Summarize the key signals in this document and list the next action items." \
  --max-tokens 400

Python

from mlx_lm import load, generate

model, tokenizer = load("LibraxisAI/Qwen3-14b-MLX-Q5")

prompt = "Summarize the key signals in this document and list the next action items."
response = generate(model, tokenizer, prompt=prompt, max_tokens=400)
print(response)

Multi-turn with the chat template

This checkpoint follows the tokenizer/chat-template contract inherited from Qwen/Qwen3-14B when the template is present in the repository:

from mlx_lm import load, generate

model, tokenizer = load("LibraxisAI/Qwen3-14b-MLX-Q5")

messages = [
    {"role": "user", "content": "Summarize the key signals in this document and list the next action items."},
]
prompt = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
response = generate(model, tokenizer, prompt=prompt, max_tokens=400)
print(response)

Example output

No public sample output is currently declared for this checkpoint.

Quantization notes

Aspect	Original/base checkpoint	This checkpoint
Lineage	Qwen/Qwen3-14B	LibraxisAI/Qwen3-14b-MLX-Q5
Runtime target	Upstream runtime format	MLX on Apple Silicon
Quantization	Base precision or upstream-declared format	Q5
Published quality delta	Not declared in public metadata	Not declared in public metadata

Limitations

• No public benchmarks for this checkpoint are declared in the model metadata.
• No public benchmark claims are made by this card unless listed in the frontmatter.
• Validate outputs on your own domain data before relying on this checkpoint.
• Memory use and speed depend heavily on the exact Apple Silicon generation, unified-memory size, and prompt length.
