Usage

python

from transformers import AutoModelForCausalLM, AutoProcessor
import torch

# Load model
model = AutoModelForCausalLM.from_pretrained(
    "qwen3_vl_8b_grpo_sld",
    device_map="auto",
    torch_dtype=torch.float16,
    trust_remote_code=True
)

processor = AutoProcessor.from_pretrained("qwen3_vl_8b_grpo_sld", trust_remote_code=True)

# Prepare inputs
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "path/to/sld_diagram.png"},
            {"type": "text", "text": "Locate the component TSS in this diagram"}
        ]
    }
]

text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = processor(text=text, images=image, return_tensors="pt").to(model.device)

# Generate
outputs = model.generate(**inputs, max_new_tokens=512)
result = processor.decode(outputs[0], skip_special_tokens=True)
print(result)

Model Performance

This model was trained using GRPO to optimize for:

Accurate bounding box prediction (IoU score)
Efficient component search (minimal steps)
Centered component detection (component in crop center)

Limitations

Trained specifically on electrical SLD diagrams
Best performance on components similar to training data
Requires high-resolution input images for accurate detection
