Qwen3-VL-4B-Instruct-Unredacted-MAX-FP8

Qwen3-VL-4B-Instruct-Unredacted-MAX-FP8 is an FP8-compressed evolution built on top of Qwen3-VL-4B-Instruct-Unredacted-MAX. This variant preserves the unredacted abliterated training strategies of the original MAX release while applying BF16 · F8_E4M3 FP8 weight compression for improved efficiency. The result is a highly capable 4B vision-language model optimized for unrestricted, detailed reasoning and captioning across complex visual inputs, with reduced memory footprint and improved hardware throughput.

[!important] FP8 (8-bit floating point) weight and activation quantization using hardware acceleration on GPUs – FP8 W8A8. Quantization W8A8 FP8-dynamic recipe – examples.

Key Highlights

• FP8 Compressed (BF16 · F8_E4M3): Weights compressed using FP8 E4M3 format while retaining BF16 compute stability for efficient deployment.
• Unredacted MAX Training: Fine-tuned to significantly reduce refusal patterns and improve instruction adherence across diverse prompts.
• 4B Parameter Architecture: Based on Qwen3-VL-4B-Instruct-Unredacted-MAX, balancing strong reasoning performance with lower VRAM requirements compared to larger 8B variants.
• Unrestricted Multimodal Reasoning: Designed for deep analysis of artistic, forensic, technical, or abstract visual content without standard safety-driven refusals.
• High-Fidelity Captions: Produces dense, descriptive outputs suitable for dataset generation, metadata enrichment, or accessibility use cases.
• Dynamic Resolution Support: Retains Qwen3-VL’s ability to process varying image resolutions and aspect ratios effectively.

Quick Start with Transformers

from qwen_vl_utils import process_vision_info
import torch

# Load the 4B Unredacted MAX FP8 model
model = Qwen3VLForConditionalGeneration.from_pretrained(
    "prithivMLmods/Qwen3-VL-4B-Instruct-Unredacted-MAX-FP8",
    torch_dtype="auto",
    device_map="auto"
)

processor = AutoProcessor.from_pretrained(
    "prithivMLmods/Qwen3-VL-4B-Instruct-Unredacted-MAX-FP8"

        "content": [
            {
                "type": "image",
                "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
            },
            {"type": "text", "text": "Provide a detailed caption and reasoning for this image."},
        ],
    }
]

text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)

image_inputs, video_inputs = process_vision_info(messages)

inputs = processor(
    text=[text],
    images=image_inputs,
    videos=video_inputs,
    padding=True,
    return_tensors="pt",
).to("cuda")

generated_ids = model.generate(**inputs, max_new_tokens=256)

generated_ids_trimmed = [
    out_ids[len(in_ids):] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]

output_text = processor.batch_decode(
    generated_ids_trimmed,

Intended Use

• Advanced Red-Teaming: Evaluating multimodal robustness and probing behavioral edge cases.
• Complex Data Archiving: Generating detailed captions for medical, artistic, historical, or research datasets.
• Refusal Mechanism Research: Studying behavioral shifts in vision-language models after abliterated fine-tuning.
• Creative Storytelling: Producing detailed visual descriptions for narrative and world-building projects.

Limitations & Risks

Critical Note: This model is designed to minimize built-in refusal mechanisms.

• Sensitive Content Exposure: The model may generate explicit or controversial descriptions if prompted accordingly.
• User Responsibility: Generated outputs must be handled responsibly and used within ethical and legal boundaries.
• Hardware Requirements: While more memory-efficient due to FP8 compression, adequate VRAM is still required for high-resolution image processing and longer generations.
