Paper

This model was produced by INTERLACE, a layer-pruning framework for Vision-Language Models. 10% of the transformer layers in Qwen/Qwen3-VL-8B-Instruct were removed using triplet-based similarity analysis, and the remaining model was fine-tuned on 1% of FineVision for a single epoch.

94.0% average relative performance retained | 10% layers dropped (3 of 36) | 33 layers remaining

🚀 Usage

python

from transformers import AutoModelForImageTextToText, AutoProcessor

model = AutoModelForImageTextToText.from_pretrained(
    "pmadinei/Interlace-Qwen3-VL-8B-10pc",
    dtype="auto",
    device_map="auto",
    attn_implementation="flash_attention_2",
)
processor = AutoProcessor.from_pretrained("Qwen/Qwen3-VL-8B-Instruct")

messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "path/to/image.jpg"},
            {"type": "text", "text": "Describe this image in detail."},
        ],
    }
]

inputs = processor.apply_chat_template(
    messages, tokenize=True, add_generation_prompt=True,
    return_dict=True, return_tensors="pt",
).to(model.device)

output = model.generate(**inputs, max_new_tokens=512)
print(processor.decode(output[0], skip_special_tokens=True))
