Huihui4-48B-A4B-vmlx-nvfp4

Huihui4-48B-A4B-vmlx-nvfp4 is an MLX vision-language checkpoint derived from huihui-ai/Huihui4-48B-A4B-abliterated, packaged for local multimodal prompting on Apple Silicon.

Intended use

Local image-and-text reasoning on Apple Silicon
Document, screenshot, chart, and visual question answering experiments
Operator-controlled multimodal prototyping where hosted inference is not desired

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
High-stakes visual interpretation without human review

Training and conversion metadata

Parameter	Value
Repository	`LibraxisAI/Huihui4-48B-A4B-vmlx-nvfp4`
Base model	`huihui-ai/Huihui4-48B-A4B-abliterated`
Task	`image-text-to-text`
Library	`mlx`
Format	MLX / Apple Silicon checkpoint
Quantization	NVFP4
Architecture	Gemma4ForConditionalGeneration
Model files	6
Config model_type	`gemma4`

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-vlm

python -m mlx_vlm.generate \
  --model LibraxisAI/Huihui4-48B-A4B-vmlx-nvfp4 \
  --image image.jpg \
  --prompt "Summarize the key signals in this document and list the next action items." \
  --max-tokens 256

Python

from mlx_vlm import generate, load

model, processor = load("LibraxisAI/Huihui4-48B-A4B-vmlx-nvfp4")
response = generate(
    model,
    processor,
    prompt="Summarize the key signals in this document and list the next action items.",
    image="image.jpg",
    max_tokens=256,
)
print(response)

Example output

No public sample output is currently declared for this checkpoint.

Quantization notes

Aspect	Original/base checkpoint	This checkpoint
Lineage	`huihui-ai/Huihui4-48B-A4B-abliterated`	`LibraxisAI/Huihui4-48B-A4B-vmlx-nvfp4`
Runtime target	Upstream runtime format	MLX on Apple Silicon
Quantization	Base precision or upstream-declared format	NVFP4
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.
