            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("PeiyangLiu/CoE-Wiki-CoE-8B")
model = AutoModelForImageTextToText.from_pretrained("PeiyangLiu/CoE-Wiki-CoE-8B")
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]:]))

CoE-Wiki-CoE-8B

CoE-Wiki-CoE-8B is an 8B vision-language checkpoint fine-tuned for Chain-of-Evidence question answering on Wiki-CoE. Given a question and candidate evidence screenshots, the model is trained to produce a structured answer with an evidence chain.

This checkpoint is intended for research on multimodal QA, visual evidence selection, and evidence-grounded reasoning over document-like screenshots.

Expected input and output

The model expects:

a natural-language question
candidate screenshot images that may contain the supporting evidence

The expected output is a JSON-style response with:

evidence_chain: the selected supporting screenshots and localized evidence
answer: the final answer

For exact prompt formatting and evaluation scripts, see the project code.

Usage

from transformers import AutoProcessor, AutoModelForImageTextToText
import torch

model_id = "PeiyangLiu/CoE-Wiki-CoE-8B"

processor = AutoProcessor.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForImageTextToText.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)

Use the same image preprocessing and prompt format as the CoE repository for reproducible results.
