Libraries

How to use baidu/Qianfan-OCR with Transformers:

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

pipe = pipeline("image-text-to-text", model="baidu/Qianfan-OCR")
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)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("baidu/Qianfan-OCR")
model = AutoModelForMultimodalLM.from_pretrained("baidu/Qianfan-OCR", 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=256)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Layout-as-Thought: structured layout recovery for complex documents

#11

The Layout-as-Thought mechanism is an elegant solution to the end-to-end vs pipeline dilemma. Traditional OCR systems chain detection→recognition→comprehension modules, which introduces error propagation and latency. Your single-model approach with optional ⟨think⟩ tokens recovers layout analysis without sacrificing the unified architecture.

Two practical questions for production deployment:

The thinking phase adds structured bounding boxes and reading order — have you benchmarked the latency impact? For real-time document processing at scale, is the overhead acceptable, or should thinking be reserved for complex layouts only?
The 192-language support is impressive. How does performance degrade on low-resource scripts (Arabic, Thai, Devanagari) compared to Latin/CJK? In multilingual document pipelines, script mixing often causes alignment issues.

The 1.024 PPS with W8A8 quantization on A100 is strong — for edge deployment on constrained hardware (mobile, embedded), do you have benchmarks for INT4 or INT8 variants?

Looking forward to testing against Arabic document layouts with mixed RTL/LTR content.
