Spaceqwen2.5 VL 3B Instruct

🚀 SpaceQwen2.5-VL-3B-Instruct

This multimodal vision - language model enhances spatial reasoning capabilities using data synthesis and expert model pipelines.

🚀 Quick Start

✨ Features

• Model Type: Multimodal, Vision - Language Model
• Architecture: Qwen2.5-VL-3B-Instruct
• Model Size: 3.75B parameters (FP16)
• Finetuned from: Qwen/Qwen2.5-VL-3B-Instruct
• Finetune Strategy: LoRA (Low - Rank Adaptation)
• License: Apache - 2.0

This model uses data synthesis techniques and publicly available models to reproduce the work described in SpatialVLM to enhance the spatial reasoning of multimodal models. With a pipeline of expert models, we can infer spatial relationships between objects in a scene to create VQA dataset for spatial reasoning.

📦 Installation

Transformers

Install qwen dependencies:

pip install qwen-vl-utils[decord]==0.0.8

💻 Usage Examples

Basic Usage

To run inference on a sample image:

from transformers import Qwen2_5_VLForConditionalGeneration, AutoTokenizer, AutoProcessor
from qwen_vl_utils import process_vision_info

model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "remyxai/SpaceQwen2.5-VL-3B-Instruct", torch_dtype="auto", device_map="auto"
)
processor = AutoProcessor.from_pretrained("remyxai/SpaceQwen2.5-VL-3B-Instruct")

messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "image": "https://raw.githubusercontent.com/remyxai/VQASynth/refs/heads/main/assets/warehouse_sample_2.jpeg",
            },
            {"type": "text", "text": "What is the height of the man in the red hat in feet?"},
        ],
    }
]

# Preparation for inference
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",
)
inputs = inputs.to("cuda")

# Inference: Generation of the output
generated_ids = model.generate(**inputs, max_new_tokens=128)
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, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)

Advanced Usage

Or run SpaceQwen2.5-VL-3B-Instruct using llama.cpp:

./llama-qwen2vl-cli -m /path/to/SpaceQwen2.5-VL-3B-Instruct/SpaceQwen2.5-VL-3B-Instruct-F16.gguf \
                    --mmproj /path/to/SpaceQwen2.5-VL-3B-Instruct/spaceqwen2.5-vl-3b-instruct-vision.gguf \
                    -p "What's the height of the man in the red hat?" \
                    --image /path/to/warehouse_sample_2.jpeg --threads 24 -ngl 99

Limitations & Ethical Considerations

⚠️ Important Note

• Performance may degrade in cluttered environments or camera perspective.
• This model was fine - tuned using synthetic reasoning over an internet image dataset.
• Multimodal biases inherent to the base model (Qwen2.5-VL) may persist.
• Not intended for use in safety - critical or legal decision - making.

💡 Usage Tip

Users are encouraged to evaluate outputs critically and consider fine - tuning for domain - specific safety and performance.
