Libraries

How to use CodeGoat24/WorldReward-qwen35-9b with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="CodeGoat24/WorldReward-qwen35-9b")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("CodeGoat24/WorldReward-qwen35-9b")
model = AutoModelForMultimodalLM.from_pretrained("CodeGoat24/WorldReward-qwen35-9b", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Usage

git clone https://github.com/CodeGoat24/WorldReward
cd WorldReward && pip install -e .

python examples/run_single_pair.py \
    --input-image  my_data/scene.jpg \
    --left-video   my_data/system_x.mp4 \
    --right-video  my_data/system_y.mp4 \
    --caption      "A sunlit street lined with colorful European-style buildings." \
    --actions      forward,forward,left+camera_down \
    --frames-per-action 8 \
    --show-reasoning

Inference needs vLLM new enough to register Qwen3_5ForConditionalGeneration:

python -c "from vllm.model_executor.models.registry import ModelRegistry as R; \
           print('Qwen3_5ForConditionalGeneration' in R.get_supported_archs())"

Results

Three-way agreement with human labels on WorldReward-Bench (760 pairs, %). All pairs count: a pair labelled tie is correct only if the model also predicts tie.
