OneDecision-VisionGuard-27B-SFT-MLX

OneDecision-VisionGuard-27B-SFT is a dense 27-billion-parameter multimodal image classification model based on Qwen/Qwen3.8-27B and trained on the ImageShield-OneDecision-Classification content-safety guardrail dataset. The model is designed to classify visual content as Safe or NSFW, with a particular focus on detecting Not Safe for Work (NSFW) sensual content and other potentially sensitive visual content. OneDecision-VisionGuard-27B-SFT performs detailed visual analysis of dress codes, clothing exposure, poses, framing, and visual settings to support conservative content-safety classification.

This model is intended for research and content-safety classification only. Any outputs generated by this model are the sole responsibility of the user. The authors and hosting platform disclaim all liability for generated content. Users must ensure safe, ethical, and lawful usage.

BF16 Variant (Base Weights)

The unquantized BF16 weights are located directly in the root of the repository:

CLI (Terminal)

python -m mlx_vlm generate \
  --model prithivMLmods/OneDecision-VisionGuard-27B-SFT-MLX \
  --max-tokens 256 \
  --temperature 0.0 \
  --prompt "Analyze the provided image and classify the visual content as Safe or NSFW based on clothing exposure, pose, and setting." \
  --image <path_to_image>

Python API

from mlx_vlm import load, generate
from mlx_vlm.prompt_utils import apply_chat_template
from mlx_vlm.utils import load_config

model_path = "prithivMLmods/OneDecision-VisionGuard-27B-SFT-MLX"

config = load_config(model_path)

image = ["<path_to_image>"]
prompt = "Analyze the provided image and classify the visual content as Safe or NSFW based on clothing exposure, pose, and setting."
formatted_prompt = apply_chat_template(processor, config, prompt, num_images=len(image))

output = generate(
    model,
