Qwen3-VL-8B-Instruct-Unredacted-MAX-FP8

Qwen3-VL-8B-Instruct-Unredacted-MAX-FP8 is an FP8-compressed evolution built on top of Qwen3-VL-8B-Instruct-Unredacted-MAX. This variant leverages BF16 · FP8 (F8_E4M3) precision formats to significantly reduce memory footprint and improve inference efficiency, while preserving the unredacted multimodal reasoning strengths of the original architecture. The result is a highly capable 8B vision-language model optimized for unrestricted, detailed reasoning and captioning across complex visual inputs, with enhanced hardware efficiency.

[!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

• BF16 · FP8 (F8_E4M3) Compression: Transformer Engine–based FP8 quantization reduces VRAM usage and improves throughput while maintaining strong multimodal reasoning fidelity.
• Unredacted MAX Training: Retains the abliterated fine-tuning strategy designed to minimize internal refusal behaviors and improve instruction adherence.
• 8B Parameter Architecture: Built on top of Qwen3-VL-8B-Instruct-Unredacted-MAX, delivering stronger reasoning capacity while benefiting from FP8 efficiency gains.
• 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.
• Optimized Deployment: FP8 compression enables smoother deployment on Hopper and compatible GPU architectures.

# Load the 8B Instruct Unredacted MAX FP8 model
model = Qwen3VLForConditionalGeneration.from_pretrained(
    "prithivMLmods/Qwen3-VL-8B-Instruct-Unredacted-MAX-FP8",
    torch_dtype="auto",

                "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)

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 lighter than larger full-precision variants, the 8B FP8 architecture still requires compatible GPU support and sufficient VRAM for high-resolution image processing and extended generations.
